Key takeaways
- Each PDF page becomes one image; choose the resolution (DPI) to control sharpness and file size.
- 150 DPI suits screens and sharing; 300 DPI suits printing and text recognition.
- PNG keeps text and line drawings crisp; JPG is smaller for photos and scans.
- An A4 page is 1240 × 1754 pixels at 150 DPI and 2480 × 3508 pixels at 300 DPI.

Why convert PDF pages to images?
Images are easier to post on social media, paste into slides and chat apps, and upload to forms that only accept pictures. The PDF to JPG tool draws each page in your browser and saves it as an image.
Choosing the resolution (DPI)
DPI (dots per inch) sets how many pixels each inch of the page becomes. Higher DPI means sharper images and bigger files.
| Use | DPI | A4 page size in pixels |
|---|---|---|
| Thumbnails, quick previews | 72–96 | 595 × 842 to 794 × 1123 |
| Screens, WhatsApp, email, slides | 150 | 1240 × 1754 |
| Printing, zooming in, OCR | 300 | 2480 × 3508 |
A US Letter page (8.5 × 11 inches) is 1275 × 1650 pixels at 150 DPI and 2550 × 3300 at 300 DPI.
JPG or PNG?
- JPG is best for scanned pages and pages full of photos: much smaller files, with slight softening.
- PNG is best for pages of text, tables, charts and line drawings: edges stay perfectly sharp, but files are larger.
Step by step
- Open PDF to JPG and choose the PDF.
- Pick the format and resolution.
- Download single pages or all pages as a ZIP.

- Need the text rather than a picture? If you can select text in the PDF, use PDF to text. For scanned pages, convert at 300 DPI and run image to text (OCR).
- Going the other way, JPG to PDF turns photos of documents into a single PDF.
