Why convert PNG to PDF?
Sharing a set of screenshots as a single PDF keeps them in order and makes them easy to read, print and attach, whether it's a bug report, a set of instructions or a design review.
PNG is lossless, and so is this conversion: images are embedded without JPG-style compression, so small text and fine lines stay crisp when zoomed or printed.
PDF is accepted almost everywhere documents are submitted, while some portals refuse image uploads.
PNG vs PDF
PNG is a single lossless image, ideal for screenshots and graphics. A PDF is a page-based document that can contain many images and prints at an exact physical size.
Transparent areas of a PNG stay transparent in the PDF; on a standard white page they simply look white.
| Property | PNG | |
|---|---|---|
| Compression | Lossless | Depends on the embedded content |
| Transparency | Yes, full alpha channel | Yes |
| Animation | Only as APNG, rarely used | No |
| Pages | One image | Any number of pages |
| Best for | Screenshots, logos, graphics with text | Sharing, printing and archiving documents |
| Support | Everywhere | Every operating system, browser and printer |
Is it safe?
Yes. PNG to PDF runs entirely in your browser. Your files are read and converted by your own device using built-in browser technology, so they are never uploaded to a server and nobody else can see them.
You can check this yourself: open your browser's developer tools, switch to the Network tab and convert a file. No upload requests are made.
The PDF is assembled on your device. Screenshots often contain private information, and here they are never uploaded anywhere.
Files stay in this tab's memory only until you remove them or close the page.
Frequently Asked Questions
Is PNG quality preserved in the PDF?
Yes. PNG images are embedded with lossless compression, so every pixel is kept exactly.
What happens to transparent backgrounds?
Transparency is kept in the PDF. On the usual white page, transparent areas look white, just like viewing the PNG on a white background.
Can I put several screenshots in one PDF?
Yes. Add them all, put them in order with the arrows, and leave Combine into one PDF on. Each image becomes one page.
Why is the PDF about the same size as my PNGs?
Nothing is compressed lossily, so the PDF holds your images at full quality plus a small amount of document structure.
How do I change the order of the pages?
Use the up and down arrows next to each file before converting. The PDF follows the order of the list.
Is there a page limit?
You can add up to 25 images per PDF, each up to 50 MB.
