About PNG to PDF conversion

A PDF wraps your images in a document that looks the same on every device and prints at a predictable size. That makes it the right choice for sending screenshots, scans or receipts to people who need to read, sign, print or archive them rather than edit them.

This converter embeds your pixels without re-compressing them as a JPEG, so the image in the PDF looks identical to the PNG, transparency included. Choose “Same as image” for a page that fits each image exactly, or A4 and US Letter to center each image on a standard page with margins. Combine mode builds one document from all your files, in the order they appear in the list.

What happens to transparency

Transparent areas stay transparent inside the PDF and show the page color, normally white. A few older PDF viewers draw transparent images with a gray or black box. If you see that, set Transparency to “Fill with white” and convert again.

When PDF is the right choice

  • Sending several screenshots or scans as a single file
  • Submitting documents to portals that only accept PDF
  • Printing images at a known page size
  • Archiving receipts, forms and signed pages

When to use something else

  • Images you still need to edit. Keep the PNG and export a PDF when you're done.
  • Strict upload size limits. Lossless pixels make large PDFs, so shrink the images first with the compress tool.
  • Images for web pages. Use WebP, JPG or PNG there.

Frequently asked questions

Can I combine several PNGs into one PDF?

Yes. Add your files, tick “Combine all images into one PDF” and use the arrows to put them in order. The PDF has one page per image.

Will the PDF be bigger than my PNG?

Usually about the same, sometimes a little larger, because the image data isn't re-compressed with a lossy codec. To make a smaller PDF, reduce the image size first or run the PNGs through the compress tool.

Which page size should I choose?

Use A4 for most of the world and US Letter in the US and Canada. “Same as image” is best for screens, because the page matches the image exactly.

Are my images uploaded to make the PDF?

No. The PDF is built inside your browser. Nothing is sent to a server.

Are my files uploaded?

No. The conversion runs in your browser, so your images never leave your device.

How many PNG files can I convert at once?

Up to 50 files, each up to 100 MB. Add them together and download everything as a ZIP.
