JPG is the right choice when a PDF page is mostly photograph, or when the file has to be small enough to email, attach or upload somewhere with a size cap. It compresses far harder than PNG, and on photographic content you will not see what it threw away.
This converter renders every page of your PDF at twice its natural size and saves it as a JPG, with a quality slider so you decide the trade. It runs inside this tab using your browser's own PDF engine, so the document is never uploaded and never sits on anyone's server waiting to be processed.
How to convert PDF to JPEG
- Add your PDF. Drag the file onto the box above or click to browse. It is read directly by this page and never leaves your device.
- Set the quality. The slider controls JPG compression. Around 82 is the sweet spot for most pages. Drop it toward 50 for a much smaller file if the page is a photo; raise it toward 95 if the page has fine text.
- Convert and download. One page downloads as a single JPG. A multi-page PDF downloads as a ZIP with one numbered JPG per page.
Why the resolution matters more than you would think
A PDF page has no inherent pixel size. It is drawn from instructions, so it can be rendered at any resolution, and the converter has to pick one. Render at the PDF's nominal 72 DPI and the result looks soft the moment anyone opens it at full size.
Every page here is rendered at twice that, roughly 144 DPI, which is the point where a standard document still looks crisp on a normal screen without producing files nobody wants to email. That choice is made for you rather than buried in an options panel.
What happens to transparency
JPG has no alpha channel, so any transparent region in the PDF has to become something. Left alone, most converters make it black, which is why people occasionally get a page with a black background out of a tool like this.
Here every page is flattened onto white before it is encoded, which matches what the page would look like printed. If you need the transparency preserved, PNG is the only option that can keep it.
Frequently asked questions
- Should I use JPG or PNG for my PDF?
- Use JPG when the page is photographic or when file size matters more than perfect fidelity. Use PNG when the page is text, a diagram, a screenshot or line art, because JPG's compression smears hard edges and leaves faint grey halos around letters. If you are not sure, and the page has any significant amount of text on it, PNG is the safer answer.
- What does the quality slider actually change?
- It sets how aggressively JPG discards detail. At 95 the file is large and nearly indistinguishable from the original. At 50 it is a fraction of the size with visible softening on edges. The default of 82 is deliberately chosen as the point where most people stop being able to tell on a normal screen.
- Is my PDF uploaded anywhere?
- No. The rendering runs entirely in your browser via pdf.js. Your file is read into memory on your own machine and written back out as images. Nothing is transmitted, so there is no copy on our side to leak, sell or be compelled to hand over.
- Why did my text-heavy page come out blurry?
- That is JPG doing what JPG does. The algorithm is tuned for photographs, where detail is continuous, and it handles the thousands of hard black-to-white transitions in a page of text badly. Raise the quality slider, or use the PDF to PNG tool instead, which is lossless.
- Is there a page or file size limit?
- None that we impose. There is no upload to time out and no server cost to meter, so the limit is your own device's memory. Very long documents will use a lot of RAM because every rendered page is held until the ZIP is assembled.
