Convert PDF to PNG
100% private — runs on your device, never uploaded. Works offline once loaded.
Turn every page of a PDF into a crisp, lossless PNG image and download them individually or as a ZIP. Everything runs locally in your browser — your document is never uploaded.
What makes PNG different from JPG
PNG uses lossless DEFLATE compression — the same family of algorithm behind ZIP files — so every pixel from the rendered PDF page comes out identical, with no compression artifacts whatsoever. The trade-off is that PNG can't shrink continuous-tone photos nearly as well as JPEG, so a page full of scanned photographs will produce a noticeably bigger PNG than the equivalent JPG.
That lossless property is exactly why PNG is the standard choice for anything with sharp edges: text, tables, flowcharts, wireframes, and line-art diagrams all stay perfectly crisp instead of picking up the faint blur or ringing that lossy formats introduce around high-contrast edges.
Typical reasons to reach for PNG specifically
Developers and technical writers converting a PDF page of a diagram, architecture chart, or code screenshot into a PNG for a README, wiki, or documentation site need every line and character to render exactly as drawn — PNG is the format that guarantees that. It's also the better pick for archiving a legal document or contract page as an image master copy, since you're not baking in any generation loss that could compound if the file gets re-compressed later.
One thing PNG will not do here
PNG supports transparency, but a PDF page is a fully painted rectangle — there's no transparent background to preserve, so the exported PNG will still have a solid white (or whatever color the page is) background rather than a see-through one. If you were hoping to lift a logo or graphic out of a PDF with a transparent backdrop, PNG export alone won't isolate it; you'd still need to manually erase the background afterward.
A quick tip
If file size matters more than pixel-perfect fidelity — say you're emailing a scanned photo page rather than archiving a diagram — convert to JPG instead; PNG is the right tool specifically when you need the output to be indistinguishable from the source.
Frequently asked questions
PNG or JPG — which should I pick?
PNG is lossless and best for text/diagrams; JPG is smaller and fine for photos. Use our PDF to JPG tool if you prefer smaller files.
Are my PDFs uploaded?
No — rendering happens locally in your browser and your files stay private.
Why is my PNG file so much bigger than a JPG would be?
PNG's lossless compression can't discard visual detail the way JPEG does, so pages with lots of color variation or photographic content compress far less efficiently.
Does the PNG have a transparent background?
No — a rendered PDF page is fully opaque, so the PNG background will be solid white or whatever color the page itself is, not transparent.
Will text in the PNG stay sharp when I zoom in?
Yes, since PNG is lossless there's no compression blur; sharpness at high zoom is limited only by the rendering resolution, not by the file format.
Can I convert just one page of a large PDF to PNG?
Yes — each page renders as an independent PNG, so you can pick and download only the pages you actually need.
Is PNG a good format for archiving scanned contracts long-term?
Yes, PNG's lossless nature means the image won't degrade if it's ever re-saved or re-processed, which makes it a safer archival choice than a lossy format for documents you may need to reference years later.
