How to use this tool
- Select your file, drag it onto the box above.
- Processing starts automatically — there is nothing to configure.
- Check the result panel, which shows the original size, the final size and the page count.
- Click Download to save it.
PNG is lossless, so text and line art stay crisp with no compression artefacts — at the cost of considerably larger files than JPG. For pages that are mostly photographs, JPG is the better choice.

PDF to PNG: what can go wrong
Most failures here are not about the document itself but about how it was produced. The ones that actually come up:
- The PDF is password-protected.
- The files are very large — that is PNG working as intended. Use PDF to JPG if size matters more than sharpness.
- The document has more than 60 pages.
How it works
Each page is rendered with pdf.js at the resolution you choose, then exported as an image. Rendering happens on your own device using your browser's canvas — the file is never uploaded.
Resolution is the main trade-off: 150 DPI suits screens and email, 300 DPI matches print quality and produces files around four times larger.
A measured run of this tool
Not an estimate. This page’s own code, run against a documented reference file.
Input: 2.92 MB. Output: 3 files totalling 8.77 MB.
Files produced: reference-scan-page-1.png, reference-scan-page-2.png, reference-scan-page-3.png.
Who needs PDF to PNG
Diagrams, charts, contracts and anything with fine text or line art where JPEG artefacts would be visible.
PDF to PNG — frequently asked questions
What resolution should I choose?
150 DPI for screen use and email. 300 DPI if the images will be printed. Higher rarely helps and makes files much larger.
Why is each page a separate file?
A PDF page maps to one image. Your browser may ask permission to download several files at once — that is expected.
Is there a page limit?
Sixty pages. Beyond that a browser tab typically runs out of memory, and failing clearly is better than crashing halfway through.
What resolution are the exported pages?
Pages are rendered at a resolution chosen to stay readable without producing enormous files. A PDF page has no inherent pixel size — it is described in points — so any export has to pick one.
Does this work on a scanned PDF?
Yes. Scanned pages are already images, so exporting them is straightforward — arguably more reliable than on a text PDF, where fonts have to be rendered.
Is this tool really free?
Yes. No account, no trial period, no watermark on the output and no cap on how many times you use it. The site is funded by advertising.

Your PDF never leaves this device. Contracts, statements and applications are processed entirely in the browser — open the Network tab while you use the page and you will see no upload (how that works).
Disclaimer. Upload limits differ between portals and are often lower than the published figure once the whole application is counted. Check the limit shown on the upload screen itself. Full disclaimer.
