Convert PNG to PDF online
Convert PNG to PDF when you need to send images as a document — a form, a set of receipts, a scanned page, a portfolio. A single PNG with no layout options is embedded losslessly with img2pdf, meaning the original image bytes are copied into the page rather than re-compressed.
When should you convert PNG to PDF?
- Submit screenshots or photos to a form that only accepts PDF
- Combine several images into one document for emailing
- Create a printable page from an image
- Archive a set of scans as a single file
Before you convert
Transparency becomes the page background
PDF pages have no alpha channel, so any transparent area in the PNG takes on the page colour.
The result is a picture, not text
Nothing in the PDF is searchable or selectable unless you turn on OCR, which adds a real text layer behind the image.
What happens to your file
A single PNG image with no layout options set is embedded into the PDF losslessly with img2pdf — the original image bytes are copied into the page rather than re-compressed. As soon as you ask for anything that changes the picture (multiple images, page size, margins, scan cleanup, OCR, or a resize), the full Pillow layout engine takes over and renders the pages instead.
Settings this conversion runs with
| Lossless path | img2pdf (JPG, PNG, TIFF) |
|---|---|
| Layout path | Pillow renderer |
| Multiple images | Combined into one PDF, drag to reorder |
What changes
- A PDF made from images is a picture of your content, not text. Nothing inside it is searchable or selectable unless you turn on the OCR option, which runs a text layer behind the image.
- PDF pages have no alpha channel, so transparent areas of your PNG become the page background.
