PDF to JPG

What resolution to pick

A PDF page has no inherent pixel size — it is drawn at whatever resolution you ask for, which is why this tool asks rather than guesses. 96 DPI is fine for something you are going to look at on a screen or attach to an email. 150 DPI is the sensible default and stays readable when zoomed. 300 DPI is what you want if the image is going to be printed or fed to OCR, at the cost of much larger files.

JPG or PNG

For a scanned document or anything with photographs, JPG is the right answer and produces far smaller files. PNG is worth it for pages that are mostly sharp line art, diagrams or screenshots, where JPG compression leaves visible fuzz around hard edges. PNG files will be several times larger.

Downloading several pages

Each page becomes its own image, with a download button underneath it, plus a button that saves all of them one after another. Browsers deliberately slow down a burst of downloads, so a long document takes a few seconds to come through and your browser may ask once whether to allow multiple files. There is no zip — that would mean loading another library for something most people do with a handful of pages.

Nothing is uploaded

The PDF is decoded and drawn inside your browser, by the same rendering engine Firefox uses to display PDFs. No copy of the document is sent anywhere, which matters rather a lot given that the documents people convert tend to be contracts, statements and identity papers.

Your files stay on your device

No PDF is uploaded here. The file is opened and rewritten inside your own browser, so there is no server holding a copy and nothing to delete afterwards. For contracts, statements and identity documents — the things people most often need to merge or split — that is the whole point.
