PDF to JPG
Render the pages of a PDF as images. Pick a resolution, choose JPG or PNG, and do the whole document or just the pages you need.
Runs entirely in your browser. Your files are never uploaded.
How to use PDF to JPG
- 1Pick a PDF, or drag it onto the box above.
- 2Choose a resolution, and JPG or PNG.
- 3Leave the pages box empty for everything, or list the pages you want.
- 4Press Convert to images and download each page.
Resolution is a choice, not a property
A PDF page has no pixels of its own. It describes shapes and text that get drawn at whatever size you ask for, which is why you have to pick a resolution rather than read one off the file. The number shown is the long edge of the image you'll get.
1000 pixels is fine for reading on screen. 1600 works out at roughly 150 DPI on A4 and is the sensible default: sharp enough to read closely, files that don't get silly. 2480 is about 300 DPI, which is what a printer wants, and the files are several times larger. Going higher than that rarely helps, because at some point you're rendering the limits of whatever was in the PDF rather than adding detail.
JPG or PNG
Use JPG for scanned pages and anything photographic. The compression is efficient and the artefacts are hard to spot on a photograph.
Use PNG for pages of text, line drawings and charts. JPG leaves a faint halo around sharp black-on-white edges, which on a page of 9pt type is the difference between crisp and slightly grubby. PNG files are bigger, often by several times, and for a page you plan to read closely that's usually worth it.
What you lose by doing this
The output is pixels. Text in the image can't be selected, searched or copied, links stop working, and a screen reader gets nothing. That's what turning a page into a picture means, rather than anything this tool does wrong, but it's worth saying because people often reach for PDF-to-image when what they actually want is the text. If that's you, copying from the PDF directly will serve you better.
Limits
- 100 MB per file.
- Password-protected PDFs need unlocking first.
- A long document at print resolution can run a phone out of memory.
Frequently asked questions
- Why does my text look fuzzy?
- The resolution is probably too low for the type size. Try the print setting, and switch to PNG, which doesn't soften sharp edges the way JPG does.
- Can I convert just one page?
- Yes, type its number in the pages box. Lists and ranges work too, like 1-3, 7.
- Why is this slower than the other PDF tools?
- Because it has to interpret and draw every page, where merging and splitting only move pages around. The page interpreter is also a sizeable download, which is why it only loads on this page.
- Can I switch tabs while a long document converts?
- Yes. The rendering deliberately avoids the browser's animation timer, which browsers stop running in background tabs, so a job carries on while you do something else.
