PDF tool
Convert PDF to PNG
Same job as PDF to JPG, different trade-off: PNG stores every pixel exactly, so there is no faint halo around letters and thin lines. That makes it the better choice whenever the page is mostly text or line art, and the worse choice when file size matters.

150 is right for reading on screen. Use 300 for printing or for running text through OCR. Higher values mostly just make bigger files.
Leave as "all", or narrow it down like 1-3, 8, 12-.

Output quality
PNG compression is lossless, so the image is a pixel-exact record of how the page was rendered — nothing is approximated and re-saving it later costs nothing in quality. That makes the result reliable for anything that will be magnified, printed or read by OCR software, where JPEG's ringing around letter edges genuinely hurts recognition accuracy. The cost is size: expect a text page at 150 DPI to land somewhere between 100 and 400 KB, several times what the same page would be as JPG.

Privacy: this tool does not upload your file
The file is never sent anywhere
This tool is JavaScript running in your tab. Your document is read from your disk into browser memory and never transmitted — not to us, not to anyone. It handles files up to 100 MB and 300 pages.
You can check this yourself
Load this page, turn off your internet connection, and run the tool. It still works. That is not a promise about our conduct — it is something you can verify in ten seconds.
Nothing to delete afterwards
There is no upload, no job record and no copy on any server, so there is no retention period. Close the tab and the working copy is gone with it.
No third parties involved
The PDF engine and its fonts are served from this domain rather than a public CDN, so no outside company sees that you used this page, or when.
Input, output and limits
Every figure below is read from the same configuration the server enforces, so this page cannot promise a limit the system will refuse.

Common use cases
Feeding pages to OCR
Text recognition works measurably better on lossless images. JPEG artefacts sit exactly on the letter edges the software is trying to read.
Diagrams and technical drawings
Thin lines are where JPEG looks worst. PNG keeps a one-pixel line as a one-pixel line, with no grey fringe.
Anything that will be edited afterwards
PNG can be cropped, annotated and re-saved repeatedly without degrading. Each JPG save compounds the loss.
Settings you can change
Resolution (DPI)
From 36 to 600, default 150.
150 is right for reading on screen. Use 300 for printing or for running text through OCR. Higher values mostly just make bigger files.
Which pages
Default: all.
Leave as "all", or narrow it down like 1-3, 8, 12-.
Troubleshooting
- The files are much bigger than I expected
- That is PNG being lossless. If the pages are mostly photographs, PDF to JPG will produce far smaller files that look the same.
- The background is transparent when I wanted white
- Pages that do not paint their own background stay transparent. Use PDF to JPG instead, which always fills the page white first.
- A long document ran out of memory
- PNG pages are held uncompressed while being written, so they are heavier on memory than JPG. Convert in ranges of 50 to 100 pages at a time.

Frequently asked questions
Browse pdf toolsShould I use PNG or JPG here?
PNG for anything with text, tables, diagrams or sharp edges — it reproduces them exactly. JPG for pages that are mostly photographs, where it will be several times smaller with no visible difference. A text-heavy page as PNG is typically two to four times the size of the same page as JPG.
Do PNG pages keep transparency?
Pages are rendered onto a transparent canvas, so areas the document never paints stay transparent rather than becoming white. Most PDF pages paint a white background themselves, in which case the result is opaque anyway.
Is anything uploaded?
No. The whole conversion happens inside this browser tab — the PDF is read from your disk, rendered locally, and the images are written straight back to your downloads. Nothing is transmitted at any point.
Where does my file go when I use this tool?
Nowhere. This tool is JavaScript that runs inside your browser tab, so the file is read straight from your disk into memory on your own device and never sent to us. There is no upload, no job record and no copy to delete afterwards — close the tab and the working copy goes with it. You can confirm this yourself: load the page, disconnect from the internet, and the tool still works. It handles files up to 100 MB and 300 pages, and those limits come from what one browser tab can hold rather than from anything on our side.
