How to convert a PDF to JPG
- Drop a PDF on the box above or click Choose a PDF. The tool shows its name, page count and size.
- Pick the image format (JPG or PNG) and the resolution. For JPG you can also set the quality.
- To convert only some pages, type them in the Pages box, for example
1-3, 5, 8-. Leave it empty for all pages. - Click Convert to images. Each page appears as a preview with its size in pixels and in kilobytes.
- Download a single page, or Download all as ZIP. Files are named after your PDF, such as
report-page-03.jpg, so they sort in page order.
Everything happens in your browser. The PDF is read from your device, drawn page by page by the open-source pdf.js engine and saved as images. Nothing is uploaded, and there is no sign-up, watermark or page limit.
Choosing resolution and format
A PDF page has a physical size, an A4 sheet is 8.27 × 11.69 inches, and resolution tells the tool how many pixels to draw per inch. The pixel size of the image is simply the page size in inches times the DPI:
- 72 DPI gives about 595 × 842 px for A4: small and fine for a thumbnail.
- 150 DPI gives 1240 × 1754 px: comfortable for reading on a phone or laptop and for sharing in chat.
- 200 DPI gives 1654 × 2339 px: sharp for slides, diagrams and small print.
- 300 DPI gives 2480 × 3508 px: the usual standard for printing and for OCR.
Use JPG for photographs and scanned pages; it is lossy but much smaller. Use PNGfor text-only pages, charts and screenshots, where it stays perfectly crisp but files are often several times larger. Pages are drawn on a white background, so transparent areas of the PDF become white in both formats.
Worked example
You have a 12-page A4 brochure and want pages 1 and 5 to 8 for a presentation. Choose JPG, 200 DPI, quality 90% and type 1, 5-8. The tool renders five pages of 1654 × 2339 px, each around 400–700 KB depending on the artwork, and offers them as brochure-page-01.jpg, brochure-page-05.jpg and so on. A ZIP of all five is a single click. If the images are too large for an email, convert again at 150 DPI: the pixel count drops by about 44% and the files shrink by roughly the same amount.
Common problems and tips
- Password-protected PDFs cannot be opened. Remove the password in a PDF viewer first (for example Print to PDF) and open the unprotected copy.
- Very long PDFs on a phone. Every page is drawn in memory as a full image. Convert in batches such as pages
1-20, then21-40. - The page looks blank. A few PDFs use features the browser engine cannot draw, or the page is really empty. Try another viewer to compare.
- Want to extract text? Images of text cannot be selected. For searchable text, use a PDF to text tool, or run OCR on the images.
- Huge pages such as posters are scaled down automatically so that the image never exceeds about 64 megapixels, which phones can handle.
Frequently asked questions
Is my PDF uploaded to a server?
No. The PDF is opened and drawn inside your browser by an open-source engine (pdf.js) that is served from this site. The file and the images never leave your device.
Which resolution should I choose?
Use 150 DPI for reading on screen and sharing, 200 DPI for sharp slides and diagrams, and 300 DPI for printing. 72 DPI gives the smallest files. Higher DPI means bigger images and longer conversion.
JPG or PNG?
Choose JPG for photos and scanned pages: files are much smaller. Choose PNG for text, charts and screenshots where you want crisp edges with no compression artefacts.
Can I convert only some pages?
Yes. Type pages such as 1-3, 5, 8- in the Pages box (8- means page 8 to the end). Leave it empty to convert every page.
Why is the conversion slow or failing on my phone?
Every page is drawn as a full-size image in memory. Long PDFs, scans and 300 DPI settings need a lot of it. Convert fewer pages at a time or pick a lower DPI.
