Convert PNG to PDF

Transparent parts of the PNG reveal the PDF page behind the image. On a normal blank PDF page, that usually appears white. The conversion does not need to fill the PNG pixels themselves with white just to place the image in a document.

Yes. Multiple images can be placed as multiple PDF pages, which is useful for assembling photos, receipts, or scans into one document. The page order matters, so arrange the images in the sequence you want before finalizing the combined file.

No. This image-to-PDF route keeps the picture as page content and does not create selectable text. If selectable text is required, use a conversion path that explicitly supports extracting text from images rather than assuming the PDF container makes the picture editable.

A PDF page has its own size and orientation, which may not match the image's aspect ratio. The image can therefore be scaled to fit while leaving margins rather than being stretched or cropped. That preserves the picture's proportions but may create unused page space.

PDF is useful when the image needs to behave like a document for printing, submission, archiving, or combining with other pages. Keep PNG when an ordinary image file is easier. This route packages the image; it does not turn the picture itself into editable text.
