How to convert PNG to PDF
- Drop your PNG files onto the box above, or click it and pick them from your device.
- Drag the thumbnails if you want a different page order.
- Pick a page size. Fit to image keeps the exact pixel dimensions of each file.
- Press Convert to PDF. The file downloads straight away.
Nothing is uploaded. The conversion runs inside your own browser. Your files never touch a server, which is why there is no queue, no size cap and no wait. You can disconnect from the internet after the page loads and it still works.
Why most converters upload your files
Most converters send your files to their server, do the work there, then send the result back. That is why they ask you to wait, cap you at a handful of files an hour, or push you toward a paid plan. It also means a copy of your file sits on someone else's machine for a while.
Browsers can do this work on their own now. This page runs locally, so the limits that come from renting server time do not apply.
Does converting PNG to PDF reduce quality?
No. PNG is lossless and it gets embedded into the PDF as is. Nothing is recompressed and no pixels are thrown away. The PDF is usually a little larger than the original because of the PDF container around it.
If you pick a fixed page size such as A4, the image is scaled to fit the page. That changes how large it appears when printed, not the stored image data.
Page size options explained
| Option | What it does | Best for |
|---|---|---|
| Fit to image | Every page matches the exact pixel size of its image | Screenshots, artwork, comics |
| A4 | 210 by 297 mm, the standard almost everywhere outside North America | Documents you will print |
| US Letter | 8.5 by 11 inches, the North American standard | Forms and letters in the US |
| Legal | 8.5 by 14 inches | Contracts and legal filings |
Common questions
Can I combine several PNG files into one PDF?
Yes. Drop as many as you like and each becomes a page in a single PDF, in the order shown in the grid. Drag a thumbnail to move it.
Does transparency survive?
PDF pages have a white background, so transparent areas come out white. That is a property of PDF, not of the conversion.
Is there a file size or page limit?
There is no limit set by this site. The practical ceiling is your own device memory. Very large jobs are slower simply because your device is doing the work.
Does it work on iPhone and Android?
Yes, in any modern mobile browser. On iPhone the finished file lands in Files or in the share sheet, depending on your browser.
Do I need to install anything or sign up?
No. There is no account, no extension and no app.
