How this PNG to PDF converter works
Drop your PNG files above, arrange them with the arrows, and click Create PDF. This PNG to PDF converter assembles the document inside your browser: each PNG becomes one page, stored losslessly, and the finished PDF downloads straight from the tab. Nothing is uploaded and nothing is kept. Because PNG is a lossless format and the PDF stores the pixels without re-compressing them, the pages look exactly like the originals, down to the last pixel of a screenshot or a line drawing.
Transparency is handled the way PDF viewers expect: transparent areas of the PNG show the page beneath, which is white in every mainstream viewer. If you want a different background, flatten the PNG in an editor first.
Where PNG to PDF earns its keep
- Screenshots into one file. Ten screenshots of a bug, a chat thread or a web page become one PDF a colleague can scroll through, in the order you set.
- Scans and signed forms. Many scanner apps output PNG; most portals want PDF. Choose A4 or Letter so the pages print at the right size.
- Design exports and diagrams. PNG keeps crisp edges, and the PDF keeps the PNG, so text in diagrams stays sharp when zoomed, unlike a JPG-based PDF.
Page size and what it does to the result
Fit to image creates a page exactly the size of each PNG (one pixel per point), which is ideal for on-screen viewing: no scaling, no borders. A4 and Letter scale the image down to fit the paper, never up, and center it; add the small margin if the PDF will go through a printer. Orientation is automatic unless you force it. None of these choices change the embedded image, so file size is almost the same whichever you pick.
Worked example: file size
Six 1920 × 1080 screenshots at about 400 KB each produce a PDF of about 2.4 MB: the PDF is the sum of its PNGs plus a few kilobytes of structure. A PDF made from the same screenshots saved as JPG at 85% would be around 900 KB but would blur the text slightly. If the destination has a hard size limit, run the PNGs through the PNG to JPG converter first and build the PDF from those; otherwise keep the PNGs.
Privacy: built in your browser
Screenshots routinely contain names, messages, balances and internal tools. This converter never sends them anywhere: the PDF is written by a library running in your tab, and you can prove it by going offline after the page loads. The same engine powers the Image to PDF converter (which also accepts JPG, WebP, HEIC and AVIF), Merge PDF and Split PDF, so a scan-to-document workflow can stay on your device from start to finish.
Frequently asked questions
›Is PNG to PDF lossless?
Yes. The PNG pixels are stored in the PDF without re-compression, so text and lines in screenshots stay sharp at any zoom.
›How big will the PDF be?
About the sum of the PNG files plus a few kilobytes. Six 400 KB screenshots make a PDF of roughly 2.4 MB. Page size settings do not change this.
›What happens to transparent areas?
They stay transparent in the PDF and show the page background, which is white in all common viewers.
›Can I mix PNG with JPG or other formats?
Yes. JPG, WebP, HEIC and AVIF files can be added to the same PDF; each is handled in its own best format.
›Are my screenshots uploaded?
No. The PDF is written by a library in your browser; the page works offline once loaded.
