Frequently asked questions

Everything you need to know about translating and converting with qlot.

Platform features

Q.Which file formats are supported?
qlot supports Microsoft Word (.docx), PowerPoint (.pptx), Excel (.xlsx), PDF, and Hangul Word Processor (.hwpx) formats. Tables, images, fonts, bullet points, and other formatting elements are preserved throughout the translation process.
Q.Which languages are supported?
qlot supports translation across more than 200 languages, including Korean, English, Chinese, Japanese, German, French, Spanish, Russian, and Vietnamese.
Q.What are the Preview plan limits?
Preview lets you evaluate qlot on your own documents before subscribing. Review the first 5 translated pages across up to 3 files, with files up to 64MB, 1 glossary, and 1-day result access. Paid plans unlock complete, unwatermarked files, monthly credits, and Excel translation.
Q.How accurate are qlot's translations?
qlot uses the latest frontier large language models to deliver translations that preserve the original meaning, tone, and formatting. For industry-specific or proprietary terminology, the Glossary feature lets you enforce consistent, pre-approved terms across every translation.
Q.What is a glossary and how do I use it?
A glossary is a custom dictionary of terms and approved translations that qlot applies automatically, keeping your terminology consistent across all documents. Create a glossary in your dashboard, then add terms manually or upload them via CSV, and select the glossary you want right before starting a translation. Each glossary is configured for a specific language direction (for example, English to Korean).
Q.Is the translated file the same format as the original?
Yes. qlot preserves your original layout. Your translated file downloads in the same format as the source file (Word, PowerPoint, Excel, PDF, or HWPX), keeping all tables, images, fonts, and structural layout intact.
Q.How long does a translation take?
Processing speed depends on the size and complexity of the document, but most standard files finish within seconds. Larger files may take a few minutes, and you can monitor progress in real time from your dashboard.

Preview and upgrades

Q.How do I download the full translation?
Choose any paid plan or the one-time Intro Offer to unlock every preview document in full. You’ll receive the complete, unwatermarked file in the same format as the original.
Q.Is the first-month payment refundable?
No. Unlocking gives you immediate access to the complete files, and you confirm immediate delivery at checkout. Once the files are unlocked, the Intro Offer is non-refundable except for billing errors, service defects, or where required by law. See our Refund Policy for full terms and renewal rules.
Q.How many documents can be translated on Preview?
Preview includes up to 3 documents per account. Translation and conversion previews share the same total. Paid plans include monthly credits for continued use.
Q.Which file formats are supported on Preview?
Preview supports Word (.docx), PowerPoint (.pptx), PDF, and Hangul Word Processor (.hwpx). Excel (.xlsx) translation is available on paid plans.

File types

Q.Can scanned PDFs be translated?
Yes. Image-only pages are detected and processed using text recognition, including mixed documents where only some pages are scanned. Results depend on the quality, resolution, and readability of the scan. When the original Word or Hancom document is available, uploading the source file will usually provide more accurate text extraction and formatting.
Q.Will the layout change if translated text is longer?
Translated text may take up more or less space than the original. qlot adjusts spacing, line breaks, and text placement to retain the document structure as closely as possible. Documents with highly complex layouts may still benefit from a final review.
Q.Can I edit the translated PDF afterwards?
You can edit the downloaded file using compatible PDF editing software. For documents that require extensive revisions, translating the original Word, PowerPoint, or Hancom file is recommended.
Q.Do I need to install anything?
No. PDF translation runs in your browser, so no additional software or plugins are required.
Q.Are .doc files supported?
qlot accepts Word documents in the .docx format. To translate an older .doc file, open it in Microsoft Word and select Save As > Word Document (.docx) before uploading.
Q.Is the table of contents translated automatically?
Yes. Table-of-contents entries are translated while the underlying reference structure is retained. After downloading the translated document, update the table of contents in Word to refresh page numbers and other field values.
Q.What happens to documents with tracked changes?
Tracked revisions and comments are translated together with the document. When only the final approved text should be translated, accept all changes and remove unnecessary comments before uploading.
Q.Can I continue editing the translated document?
Yes. The translated file is returned in the .docx format and can be opened, reviewed, and edited in Microsoft Word or compatible document software.
Q.Will translation change my formulas?
No. Formula cells are excluded from translation. Functions, expressions, and cell references remain connected to the original workbook data.
Q.Which cells are translated?
qlot translates text stored in standard text cells. Formula cells, numeric values, and date values are not translated. Text used in supported chart titles, axis labels, legends, and sheet names may also be translated.
Q.Does qlot handle workbooks with multiple sheets?
Yes. All worksheets are processed together, with their order and individual structure retained. Terminology can be translated consistently across related sheets within the same workbook.
Q.Are numbers, dates, and currencies changed?
No. Numeric and date values remain unchanged. Existing display formats, including currency symbols, percentages, decimal formats, and date patterns, remain applied to their cells.
Q.Are charts and formatting retained?
Chart structure, data series, cell formatting, merged ranges, borders, fills, and conditional-formatting rules remain in place. Supported chart titles, labels, and legends are translated with the workbook text.
Q.Will translated text overflow its text boxes?
Translated text may take up more or less space than the original. qlot adjusts font size and line spacing within the available text area to reduce overflow and retain the slide structure. Presentations with dense text or large differences in language length may still benefit from a final visual review.
Q.Are speaker notes translated?
Yes. Speaker notes are translated together with the content of their corresponding slides.
Q.Are tables and charts translated?
Supported text within tables is translated while the existing cell structure remains in place. Chart titles, axis labels, and legends are also translated while the underlying chart structure and data remain unchanged.
Q.Are animations and transitions preserved?
Existing object animations and slide transitions remain attached to the presentation. They are retained rather than rebuilt during translation.
Q.Why do I need to convert .hwp files to HWPX?
qlot processes Hancom documents in the HWPX format. HWPX uses a structured document format that allows supported text, layouts, tables, and other document elements to be processed. To convert, open the .hwp document in Hancom Office, choose Save As from the File menu, and select HWPX Document as the file type, then save the converted file. Review the converted document before uploading, particularly when it contains complex formatting, WordArt, or other Hancom-specific objects.
Q.Will official document forms and tables remain intact?
qlot retains supported page layouts, table structures, merged cells, frames, page numbers, headers, and footers. When translated text requires more space, content is adjusted within the available layout. Documents with dense tables or complex proprietary objects may benefit from a final review.
Q.What happens to Hancom-specific objects?
Standard document text, tables, frames, footnotes, headers, and footers are processed with the document. Some proprietary objects, including certain WordArt elements, may be retained as images rather than translated as editable text.
Q.Can I edit the translated document afterwards?
Yes. The translation is returned as an HWPX file that can be opened and edited using compatible Hancom software.
Q.Will a transparent logo still be transparent after translation?
Yes, when the PNG is transparent through an alpha channel or a palette entry: the delivered PNG is transparent too, so the translated wordmark can be placed over any background at the same pixel size.
Q.How are buttons, menus, and dialog text handled in screenshots?
AI vision reads the interface text and translates it with the whole screen as context, so the wording suits the role of each control rather than being handled line by line, then sets it back in the same position. Since the screenshot is regenerated rather than patched pixel by pixel, fine detail such as a drop shadow may be re-rendered, but toolbars, icons, and flat colour areas come back recognisably the same.
Q.What happens to a 16-bit or palette PNG?
Both are accepted. Output is 8-bit per channel, so a 16-bit PNG or an indexed-colour PNG is returned as a standard 8-bit PNG at the original width and height: truecolour for colour sources, greyscale for greyscale sources. The embedded colour profile is kept, and transparency is kept when it comes from an alpha channel or a palette entry, so a cut-out logo saved as an indexed PNG still comes back transparent.
Q.Which PNG uploads are declined or fail?
Animated PNG (APNG) and images whose shorter side is under 256 pixels are declined before any charge. Images without readable text, and extremely tall or wide captures of around 3:1 or more like a full-page scroll or banner, are not processed and nothing is charged. One still image is processed per upload, so split a scrolling-page capture into screen-height pieces and upload each one.
Q.Does the translated JPG still record where the photo was taken?
No. The delivered JPG carries no device name, capture date, or GPS coordinates, so a phone photo of a menu or shopfront no longer records where it was taken. Only the EXIF block goes. The photo's ICC colour profile stays embedded, so the file is read in the same colour space as the upload and still opens as an ordinary JPG. Keep your original if you need the shooting data later.
Q.Does the translated JPG keep the original compression quality?
Yes. The delivered file is encoded with your upload's own quantisation tables and chroma subsampling, whether 4:4:4, 4:2:2, or 4:2:0, rather than a generic quality setting. A progressive JPEG comes back progressive, and the width and height are unchanged, so the file drops into a website or catalogue in place of the original.
Q.Can I translate a scanned page saved as a JPG?
Yes. A scanned letter, form, or book page is read by AI vision like any other photograph, and the translated text is set back on the page in its original positions. The result is still a picture of the page. If you have the original document file the scan came from, translating that instead gives you editable text.
Q.Which JPG uploads are declined?
Images whose shorter side is under 256 pixels are declined before anything is charged. Both .jpg and .jpeg extensions are accepted, one image per upload. A photo with no readable text, or one whose long side is around three times its short side or more, is not processed and not charged.
Q.Do I get a HEIC back, or a JPG?
A HEIC. The translated photo is written in the same format your device saved, at the same pixel dimensions and with the same colour profile, rather than converted to JPG along the way. Translation never changes the file type. If you do want a JPG or PNG, qlot's separate image conversion feature handles that afterwards.
Q.Does a 10-bit HEIC keep its colour depth?
No. Delivery is 8 bits per channel, so a 10-bit HEIC from a recent iPhone comes back as a standard 8-bit HEIC with the Display P3 profile carried over, at the same pixel dimensions.
Q.Do the camera details and GPS stay in the translated HEIC?
They are removed. EXIF and camera metadata, including the device model, capture date, and GPS coordinates, are not written into the delivered HEIC, so sharing the translation does not share where you took it. If you need the capture date or location later, keep the original in your photo library, because the translated HEIC carries neither.
Q.Which HEIC files are declined?
Bursts and other multi-image HEIF sequences are declined, since only a single still is translated, as are photos with no readable text and photos whose shorter side is under 256 pixels; none of these is charged. An extremely wide or tall shot, around 3:1 or more, such as a full-length receipt or a banner, may not be processed, and an upload that fails with an error is never charged either.
Q.What is the difference between HEIF and HEIC?
.heif and .heic are two extensions of the same HEIF container, so the same width, height, colour profile, and transparency rules apply to both. qlot accepts both and returns each with the extension it arrived with, so a .heif stays .heif and a .heic stays .heic.
Q.Is a 10-bit HEIF from my camera supported?
Yes. The text is read and translated from the full image, and the result is written back as a standard 8-bit HEIF. If you need the original bit depth for grading or printing, keep the original capture alongside the translated copy, since the delivered file is 8-bit per channel.
Q.Will the colours in my HEIF shift after translation?
Colours are approximated from the source when the image is regenerated; the embedded ICC profile is carried over so the result is interpreted in the same colour space, and an RGB HEIF stays RGB while a greyscale one stays greyscale. Bit depth is the one thing that does change: a 10-bit capture comes back as standard 8-bit colour.
Q.Which HEIF files are declined before translation?
HEIF bursts and image sequences, which hold several frames in one container, are declined before any charge, as are images whose shorter side is under 256 pixels. Save the single frame you want and upload that. A HEIF with no readable text, or an extremely wide or tall one, around 3:1 or more, such as a long receipt or a banner, is not processed; the upload fails with an error and nothing is charged.
Q.Will a lossless WebP come back lossless?
Yes. The encoding of the upload is kept: lossless in, lossless out, and lossy in, lossy out, at the pixel dimensions of the original. The file is never converted to PNG or JPG, and any EXIF block the export carried is dropped. Because the image is regenerated rather than pixel-edited, fine texture may be re-rendered; the picture remains recognisably the same.
Q.Is the transparent background kept on a cut-out product image?
Yes. When the WebP has an alpha channel, the delivered image has the same transparency, so a product cut-out still sits on whatever background the page gives it. For a lossless WebP the delivery is lossless and the encoder keeps the colour values of fully transparent pixels rather than discarding them.
Q.Can I translate an animated WebP or a wide banner?
No for animations: a multi-frame WebP is declined before any charge, since the translation works on a single still frame. Save the frame with the text as its own WebP and upload it. Very wide or tall strips, at around 3:1 or beyond, may not be processed; the task then fails and nothing is charged. A thumbnail whose shorter side is under 256 pixels is declined before any charge.
Q.Can I edit the translated text in the WebP?
No. The download is a WebP image, so the translated headline and button copy are pixels rather than editable text layers. To keep the text editable, translate the design file the banner was exported from and re-export it. To publish the banner as a PNG or JPG rather than a WebP, use qlot's separate image conversion feature.
Q.Will the translated file still open in my spreadsheet or import tool?
Yes. The delivered CSV keeps the delimiter, quoting, line endings, and encoding of the upload, and every non-text cell is copied through unchanged, so column positions and data types are exactly as exported. If the target language cannot be written in the original encoding, the file is delivered as UTF-8 with a byte-order mark, which Excel and most import tools read correctly.
Q.Does qlot change numbers, dates, or product codes?
No. A cell that holds a number, date, boolean, URL, email, identifier, or formula is recognised as data and reproduced verbatim, leading zeros included. Only cells that contain text in the source language are translated.
Q.Is the header row translated?
Yes. Column headings are translated with the same per-cell rules as the rest of the file, so a heading that is a code stays a code while a descriptive heading is translated.
Q.Which CSV files are declined?
Files whose encoding cannot be detected, whose delimiter cannot be determined, or that contain no text in the source language are declined before any charge, as are files with millions of cells. If the translation comes back largely unchanged, the task fails and nothing is charged. Each upload is a single CSV file.

Convert

Q.Will my PDF fonts change in Word?
Yes. A PDF may reference fonts that are not embedded or available to Word. The converter substitutes the closest usable font when necessary, which can change character widths and shift line breaks even when the wording itself is recovered correctly.
Q.Can a scanned PDF become an editable Word file?
Yes. Scanned PDFs are supported through text recognition before the Word file is rebuilt. The result depends on the scan: clean, straight pages with clear type read best, while blur, low contrast, handwriting, or damaged text can require corrections after conversion.
Q.Can I edit PDF text in the JPG?
No. After PDF is rendered to JPG, the letters are part of the image pixels or page graphics rather than editable document text. You can crop, annotate, or place the image elsewhere, but changing the wording requires editing the source document or using an editable conversion route.
Q.Why did my PDF become several JPG files?
The converter creates one JPG image for each rendered page. A multi-page PDF file therefore becomes multiple image files, delivered together. This is intentional: combining every page into one image would make long documents difficult to view and reuse.
Q.Can I choose specific PDF pages?
Yes. This PDF conversion supports page selection, so you can limit the job to the pages you actually need. That also reduces the number of JPG files produced when the source is long, because each selected page becomes its own rendered output.
Q.Does converting a file use credits?
Conversion is included with your qlot account rather than billed separately. Each converted file draws 10 credits from your plan's monthly allowance — the same pool your translations use.
Q.Do conversions count toward my monthly file limit?
No. Your plan's files-per-month count applies to translations only, so a file conversion does not use any of those files.
Q.How large a file can I convert?
Conversions use the same file-size limits as translations, from 64MB on Preview to 1GB on Enterprise. See the pricing page for limits by plan.
Q.How many conversions can I run at once?
Each plan sets how many conversions can run at once: 1 on Preview and up to 10 on Team. Enterprise limits are set by agreement.
Q.Which file conversions are supported?
102 conversions across documents, images, spreadsheets, data files and subtitles, including PDF, Word, Excel, PowerPoint, common image formats and ebooks. The conversion hub lists every pair.

Security and data

Q.How are uploaded files secured?
All uploaded files are encrypted in transit using TLS and stored in AWS S3 with AES-256 encryption. Infrastructure is hosted on AWS (certified to ISO 27001 and SOC 2) with Cloudflare for additional network security.
Q.Are uploaded files used to train AI models?
Files and translations on paid plans are never used for AI training. Preview-plan content may be used, after de-identification, to improve our translation models — use any paid plan to exclude your content. Uploaded source files are automatically deleted within 24 hours of processing.
Q.Is qlot compliant with data-protection regulations?
Data privacy is our top priority. qlot runs on infrastructure that is ISO 27001 and SOC 2 certified, and we comply with rigorous data-protection standards, including the Personal Information Protection Act (PIPA), to guarantee strict confidentiality and security for all corporate data.
Q.How do I delete my account and data?
You can permanently delete your account and all associated data from your account settings, or by contacting our support team at hello@qlot.ai. Once processed, your files, glossaries, and personal history are permanently removed from our systems.

Billing and pricing

Q.How do I subscribe to an Enterprise plan?
Enterprise plans include on-premises deployment, SSO integration, dedicated account management, and a service-level agreement. Please contact the qlot sales team through the Contact page to begin the procurement process.
Q.How are credits consumed?
Credits are deducted based on how much text your document contains and the language direction. A dense, full standard page runs 10–30 credits depending on the direction, and typical documents usually cost less.
Q.How much does it cost to translate a contract?
It depends on the file's volume and the language direction. A typical 20-page document takes about 100–250 credits — roughly $0.21–$0.53 at the Pro plan's per-credit price ($0.0021). Upload a file and you'll see the exact credits before you commit.
Q.Are credits deducted if a translation fails?
No. If a translation doesn't complete successfully, no credits are used. If any were already deducted, they're returned automatically.
Q.Can I get credits back if I'm not happy with the result?
If you're not satisfied with a translation result, you can submit a credit refund request. Requests are reviewed individually, and approved credits are returned to your account. Using a glossary improves the consistency and quality of proper nouns and technical terms.
Q.Can I buy more credits if I run out mid-month?
Credits refill on your monthly renewal date, and separate top-up purchases aren't offered. If you've used all your credits, you can wait for the next renewal or upgrade to a higher plan — the new credit allowance applies immediately when you upgrade.
Q.Are Team credits provided per member?
No. Team credits are shared by the whole workspace. Seats × 20,000 credits per month are provided as shared credits, and every member draws from the same pool.
Q.Can I translate scanned PDFs? Do they cost more credits?
Yes. Scanned documents are translated after OCR text recognition. Credits are deducted by translation volume just like regular documents, and an OCR page limit may apply depending on your plan.
Q.How do I cancel my subscription?
You can cancel your subscription at any time from your account's billing settings. Your plan remains active until the end of the current billing period, after which it will not renew.
Q.Can I get a refund?
Refunds are handled in accordance with our Terms of Service and applicable consumer protection law. To request a refund, please contact our support team through the Contact page.
Q.Can I change my plan later?
Yes. You can upgrade or downgrade your plan at any time from your account's billing settings. Changes take effect according to your billing cycle.
Q.Do unused credits roll over to the next period?
Your credit allowance resets every month, and unused credits do not carry over to the next billing cycle.
Q.Is there a free trial?
Every new account starts with Preview, so you can see qlot translate your own documents before subscribing. The one-time Intro Offer unlocks every preview document and includes 30 days on the paid plan that fits those files, at a reduced first-month price. The plan then renews at its standard rate unless cancelled.
Q.What happens when I run out of credits?
Once you've used your plan's credits, translation pauses until your next billing cycle resets. To continue right away, you can upgrade your plan or add more seats. You will never face unexpected overage charges.

Team and API

Q.How does Team plan billing work?
The Team plan is billed per seat. Each seat adds 20,000 credits per month to a shared organizational balance, and all members get access to unlimited shared team glossaries. Workspace admins can add or remove seats anytime from the dashboard.
Q.Can I share glossaries with my team?
Yes. On the Team plan, glossaries are shared automatically across all members, so your entire team translates with the same approved terminology.
Q.Does qlot offer an API?
Yes. qlot provides a translation API for integrating translation into your own systems and workflows. API access is available on the Enterprise plan. See our API documentation or contact our sales team for integration details.

International billing

Q.Why does my card statement show a charge from Paddle?
For customers outside our Korean checkout, our order process is handled by Paddle.com, our authorized reseller and Merchant of Record. Charges appear on your statement as PADDLE.NET* QLOT, and you can look up any charge at paddle.net.
Q.What currency am I charged in, and are taxes included?
Paddle charges you in your local currency based on your country — the exact figures you see at checkout. Listed prices exclude tax; any applicable VAT or sales tax is calculated and itemized at checkout.
Q.How do I get invoices or manage my international subscription?
Paddle emails a receipt for every charge, and past invoices are available at paddle.net. You can change plans or cancel anytime from your qlot dashboard. Refunds follow our Refund Policy and can be requested via hello@qlot.ai or paddle.net.
