PNG to PDF — Convert PNG Images to PDF Online Free

What is the PNG to PDF tool?

The PNG to PDF tool converts PNG images — screenshots, diagrams, exported designs, scanned pages — into a single PDF. PNG’s lossless detail is kept, so text inside screenshots stays razor sharp, which is exactly what you want when submitting proof, documentation or design reviews. Add several PNGs and they become ordered pages of one document.

Key features

Lossless PNG detail preserved — screenshot text stays sharp
Combine many PNGs (and JPGs) into one ordered PDF
Fit-to-image pages or standard A4
One-tap removal of any image before converting
100% in-browser — screenshots of private apps never leave your device

How do I use it?

Select or drop your PNG files (JPGs can be mixed in too).
Arrange the list — remove any image you don’t want.
Pick Fit to image or A4.
Click Create PDF & download.

Is it safe to convert PNG to PDF online?

Yes. Each PNG is embedded losslessly into the PDF by code running in your browser, producing a standards-compliant ISO 32000 PDF standard file. Screenshots often contain private chats, dashboards or account details — with on-device conversion none of that is ever transmitted.

Tips for the best result

Screenshots convert best with Fit-to-image — no scaling, maximum sharpness.
Many long screenshots? Consider cropping first so pages aren’t extremely tall.
Mix PNG screenshots with JPG photos freely — both are supported.
Need a smaller file? PNGs are large; run Compress on the result if size matters.

Frequently asked questions

Will my PNG screenshots stay sharp in the PDF?

Yes — PNGs are embedded losslessly, so fine text in screenshots remains perfectly crisp.

Can I combine several PNGs into one PDF?

Yes, add as many as you like; each becomes a page in the order shown in the list.

Does PNG transparency cause problems?

No — transparent areas render over white in the PDF, which is what viewers and printers expect.

Can I mix PNG and JPG files?

Yes, both formats can be combined in a single conversion.

Why is my PDF large after converting PNGs?

PNG is lossless and therefore big. If file size matters, compress the finished PDF with the Compress tool.

Are my screenshots uploaded during conversion?

No. The conversion is done entirely on your device — nothing is sent anywhere.
