How to use the PDF to JPG

- Choose JPG or PNG, the resolution in DPI and, for JPG, the quality.
- Leave the page box empty to convert every page, or type the pages you need, such as 1-3, 5.
- Click Convert. Download any image from the gallery, or all of them in one ZIP.

Why convert a PDF to images?
Images go where PDFs cannot. Social networks, chat apps and many website builders accept pictures but not documents. Some upload forms ask for a JPG of a certificate or ID even when you only have a PDF. Presentation software is happier with an image of a chart than with an embedded document, and an image previews instantly on any phone. Converting the right pages to images bridges all of these gaps.
Choosing the resolution
A PDF page has a physical size, and DPI (dots per inch) decides how many pixels each inch becomes. The table shows what that means for a US Letter page (8.5 × 11 inches):
| DPI | Image size | Good for |
|---|---|---|
| 72 | 612 × 792 px | Thumbnails, quick previews, chat messages |
| 150 | 1275 × 1650 px | Reading on screen, websites, slides |
| 200 | 1700 × 2200 px | Zooming into small print, detailed charts |
| 300 | 2550 × 3300 px | Printing and archiving |
Doubling the DPI quadruples the number of pixels, so file sizes and conversion time grow quickly. 150 DPI is a sensible default; choose 300 only when the images will be printed or need to stay sharp when enlarged.
JPG or PNG?
JPG uses lossy compression tuned for photographs. At 85–95% quality it looks clean and stays compact, which makes it the right choice for pages with photos and for sharing. PNG is lossless, so text edges and thin lines stay perfectly crisp, but files are larger, especially for photo-heavy pages. For a text page, PNG at 150 DPI is often the best-looking option; for a brochure full of pictures, JPG at 90% is usually smaller with no visible difference.
How the conversion works
Each page is drawn by PDF.js, the same open-source engine that displays PDFs in Firefox, onto a canvas in your browser at the resolution you chose, and then encoded as an image. Transparent areas become white, just as they appear when the page is printed. Pages are converted one at a time, so even a long document will not exhaust your device’s memory, and you can stop at any point and keep the pages that are already done.
Tips
- Converting only the pages you need is much faster than converting a whole report.
- To extract the words rather than a picture of them, use PDF to Text.
- Need a smaller JPG afterwards? Run it through the Image Compressor or crop it with the Image Cropper.
- To go back the other way, JPG to PDF turns images into a document.
Frequently asked questions
What resolution should I use to convert PDF to JPG?
150 DPI suits screens, slides and websites. Use 300 DPI for printing or when you need to zoom into small text, and 72 DPI for small previews.
Can I convert only some pages?
Yes. Type the pages you want, such as 2, 4-6, in the pages box. Leave it empty to convert every page.
Is PNG better than JPG for PDF pages?
PNG keeps text and line art perfectly sharp but makes larger files. JPG is smaller and ideal for pages with photos. Try both if you are unsure.
Can I convert a password-protected PDF?
Yes, if you know the password. The tool asks for it when the file is locked, and it is used only inside your browser.
Are my PDF and images uploaded anywhere?
No. Pages are rendered and saved as images by your browser, on your own device.
