How it works
- Drop your PDF onto the tool.
- Keep PNG selected and pick a resolution — 150 dpi for screen use, 300 dpi for print.
- Click Convert, then download pages individually or all together as a ZIP.
Frequently asked questions
- Why PNG rather than JPG?
- PNG is lossless, so it stores exactly what was rendered. On pages of text, tables, charts and line drawings that matters: letter edges stay razor-sharp and you avoid the faint grey halos JPEG leaves around dark text on a white background. The cost is file size — for a photographic page a PNG can be several times larger than an equivalent-looking JPG.
- Do PNGs from a PDF have transparent backgrounds?
- No. PDF pages have a defined page area that is painted, so what you get is the page as it appears, white background included. If you need a transparent cut-out you will have to remove the background afterwards, which is a separate editing job.
- Which resolution should I choose?
- 150 dpi for screen use — an A4 page becomes roughly 1240 × 1754 pixels, plenty for reading and for most web uses. 300 dpi for print or when the image will be viewed at full size, giving about 2480 × 3508. Because PNG is lossless, 300 dpi files get large quickly, so do not reach for it by default.
- The conversion failed on a long document. Why?
- Memory. Each page is rendered to a full uncompressed bitmap before encoding — around 25 MB for A4 at 300 dpi — and PNG encoding of large images is itself demanding. Pages are freed as the tool progresses, but a long document at high resolution can still exhaust a phone. Use 150 dpi, or split the PDF and convert the parts.
- Is my file uploaded to a server?
- No. The PDF is rendered by your own browser and the PNGs are produced on your device. Even the rendering engine is served from this site rather than a third-party CDN, so no external service receives your document or any signal that you opened it.
About this tool
PNG is the right output when the pages are documents rather than photographs. Its compression is lossless, so a rendered page of text keeps perfectly clean letter edges, tables keep hairline-sharp rules, and charts keep flat areas of solid colour without the mottling that lossy compression introduces. If you are converting a contract, a form, an invoice or a diagram, PNG is what you want.
The comparison with JPG is straightforward. JPEG discards detail the eye is unlikely to notice, which works beautifully for continuous-tone photographs and poorly for hard black-on-white edges — the artefact you see as faint grey shadows around text. PNG discards nothing, so text looks exactly as rendered, at the cost of a bigger file. For a photographic scan, JPG is the sensible choice and this site has a dedicated tool for it.
Resolution decides both quality and size. At 150 dpi an A4 page becomes about 1240 × 1754 pixels, which is comfortable for on-screen reading and most web use. At 300 dpi it is about 2480 × 3508 — the right choice for printing or for viewing at full size, but roughly four times the pixels, and lossless encoding means the files grow in proportion. Choose 300 only when you need it.
Rendering happens entirely in your browser, with the PDF engine served from this site rather than a CDN, so your document never leaves your device and no third party learns that you opened it. The only real ceiling is memory: each page becomes a large uncompressed bitmap before it is encoded, and although pages are released as they complete, long documents at 300 dpi can still overwhelm a phone. Dropping to 150 dpi or splitting the file first resolves it.
