JPEG or PNG?
JPEG for pages that are mostly photographs or scans, and for anything you need to email. PNG for pages of text, diagrams and screenshots, where JPEG compression smudges the edges of letters.
PDF to JPEG or PNG
Choose the pages and the resolution. Each page is rendered on this device and handed back as an image — one file, or all of them in a single archive.

What this tool does, exactly
- What it does
- Draws the pages you ask for at the resolution you choose and hands them back as JPEG or PNG files. More than one page also arrives as a single .zip, because no browser will start thirty downloads in a row.
- What to choose
- PNG for text, diagrams and screenshots; JPEG for scans and photographs, and for anything that has to go in an email. 150 dpi gives about 1240 × 1750 pixels for an A4 page.
- Where it stops
- Your device's memory. A long document at 300 dpi can exhaust a phone; the tool stops and says so rather than handing you a truncated set.
About this tool
What resolution should I choose?
150 dpi is a good default and gives roughly 1240 by 1750 pixels for an A4 page. Choose 300 dpi only if the result will be printed or magnified; on a phone, a long document at 300 dpi can run out of memory.
Why did I get a .zip?
Because browsers, and Mobile Safari in particular, will not start thirty downloads in a row. When there is more than one page the images are also packed into a single archive so one tap gets everything. The individual files are still listed underneath.
Are the images uploaded anywhere?
No. The rendering happens in this browser tab and the files exist only in this tab's memory until you save them or leave the page.
