How to convert a PDF to JPG
- Choose your PDF. Drop it onto the box or tap to pick it. If it has a password, type it when asked.
- Pick the format and resolution. JPG for small files, PNG for crisp text. 150 dpi suits screens and most uploads; 300 dpi suits printing.
- Pick the pages. Every page is selected at first. Tap pages to leave them out, or type a range such as
1-3, 5in the Pages box. - Convert and download. One page downloads as a single image; several pages come as a ZIP, with a button for each page if you only need one or two.
Choosing the resolution
A PDF page has no pixels of its own: its text and drawings are shapes that can be drawn at any size. The resolution decides how many pixels each inch of the page gets in the image. The table shows what that means for a US Letter page (8.5 × 11 inches); an A4 page is about the same.
| Resolution | Letter page in pixels | Use it for |
|---|---|---|
| 72 dpi | 612 × 792 | Thumbnails and quick previews |
| 150 dpi | 1275 × 1650 | Screens, slides, chat apps and most upload forms |
| 300 dpi | 2550 × 3300 | Printing, and zooming into small print |
| 600 dpi | 5100 × 6600 | Fine drawings and plans |
Browsers refuse to make images above a certain size (on iPhones about 16 megapixels), so a very large page at 600 dpi is drawn at the highest resolution the browser allows, and the result says when that happened.
JPG or PNG?
JPG files are small and every app, website and upload form accepts them, which makes JPG the right choice for most pages, especially those with photos. JPG stores pictures with slight losses that you don't see in photos but can notice as faint fuzz around black text on white. PNG stores every pixel exactly, so text, signatures and line drawings stay perfectly crisp; the price is a file several times bigger. The JPG quality menu trades size for detail: High is indistinguishable from the original for nearly every page.
Private, with no limits
The pages are drawn by pdf.js, the PDF reader built into Firefox, running in your browser from this site, and the images are created on your device. No page, file name or password is sent anywhere, and there is no page limit, watermark or sign-up. Scanned PDFs work too: pdf.js reads the JPEG, JPEG 2000, JBIG2 and CCITT images that scanners produce.
Troubleshooting
- "Out of memory" on a phone: convert at 150 dpi, or a few pages at a time.
- The images are too big to upload: shrink them to an exact size with the image compressor.
- You want a smaller PDF, not images: use the PDF compressor instead.
- The page order is wrong, or pages are sideways: fix them first with Merge PDF, which can also reorder, rotate and delete pages of a single file, then convert the result.
