PDF to images
Turn the pages of a PDF into images: choose the format, the resolution and which pages. A single page comes out as an image, several pages in a zip archive.
Your file stays on your device: nothing is uploaded
How it works
Pages are drawn by Mozilla’s rendering engine at the requested resolution, and the pixels then go to our own JPEG encoder — the same one “Compress images” uses, which at equal size gives visibly better quality than the browser’s. PNG is lossless and the right choice for text and charts; JPEG is far lighter on scans and photos. Resolution is the parameter that really matters: 150 DPI reads well on screen, 300 is for printing, 600 almost only for archiving. Mind the weight: at 600 DPI an A4 page is 5100×6600 pixels, which is 128 MB of memory while it is being drawn and several megabytes once saved. Pages are drawn one at a time and the memory is freed immediately, but the produced images all stay until the zip is built: on a long document at high resolution the browser may not cope. If that happens, lower the resolution or export the pages in groups.
Your files are never uploaded. Anywhere.
Not to a server of ours, not to a third party, never. When you pick a file it stays in your browser’s memory: it is read, processed and written back on your device, and you save the result yourself. There is no path that takes it elsewhere, because there is no server to send it to.
- Processed locallyFormats are handled by WebAssembly code running in your browser, not by a remote service.
- Nothing to upload, nothing to wait forOther services send your file to a server and then send it back to you. Here the file never leaves: there is no upload to wait for.
- No accountNo sign-up, no email, no daily limits to get around by paying.
- No files to deleteOthers promise to erase your files after an hour. We have nothing to erase: they never reached us.
