How do I convert a PDF to JPG?
Choose the PDF, pick JPG or PNG and a resolution (150 dpi suits screens, 300 dpi suits printing), then press Convert pages. Every page, or just the range you type, is drawn as a picture that you can download one by one or all together in a ZIP. Your browser does the work, so the PDF is never uploaded.
Turning pages into pictures
Sometimes a PDF is the wrong format: a website wants a picture, a slide needs one page as an image, or you want to post a page on social media. Converting a page to JPG or PNG gives you a picture of it exactly as it looks, including fonts and layout.
A PDF page is measured in points, 72 to the inch, so the resolution you choose sets the size of the picture. At 72 dpi one point is one pixel, which suits a quick preview. A US Letter page (8.5 × 11 inches) is 1275 × 1650 pixels at 150 dpi, a good size for screens and documents, and 2550 × 3300 pixels at 300 dpi, the usual choice for printing. Higher resolutions give sharper pictures and much bigger files, so choose the lowest that looks right. PNG keeps text crisp and is best for pages with sharp lines and few photographs. JPG is smaller and better for photographic pages.
It runs in your browser. Your PDF is never uploaded, and there is no watermark or sign-up.
How it works in detail
Your browser opens the PDF with PDF.js, on your device. Each page you choose is drawn on a canvas at a scale of dpi divided by 72, because a PDF page is measured in points of 1/72 inch: a US Letter page (8.5 × 11 in) at 150 dpi comes out at 1,275 × 1,650 pixels, and at 300 dpi at 2,550 × 3,300. The canvas is saved as a JPG on a white background (with a quality from 1 to 100) or as a PNG, and you download each picture or all of them in a ZIP. Pages that would be larger than about 100 million pixels are refused, because many devices cannot draw them. Fonts that are not embedded in the PDF are replaced with standard ones, so the look can differ slightly from a desktop viewer. Pages are drawn one at a time to keep memory use down.
How to use it
- Choose the PDF.
- Pick the resolution: 72 to 96 dpi for small previews, 150 dpi for screens, 300 dpi for printing.
- Choose JPG (smaller files; set the quality) or PNG (sharper edges, larger files).
- Type the pages you want, such as 1-3, 5, or leave it empty for all pages.
- Press Convert pages, then download pictures one by one or all together as a ZIP.
What changes and what stays the same
What the tool does to your file, and what it leaves alone.
| Aspect | What happens |
|---|---|
| Appearance | Each page is drawn as a picture, so text is no longer selectable |
| Resolution | Width in pixels = page width in inches × dpi |
| Background | White for JPG; PNG also uses the page background |
| Pages | All of them, or the ones you type, one picture each |
| The original file | Never changed: the tool builds a new file and the original stays where it is |
| Privacy | The PDF is read on your device and is not uploaded; there is no account and no watermark |
When to use it
- Putting a page of a PDF on a website or in a presentation
- Making a thumbnail or preview of a document
- Sending a page as a picture in a message
- Extracting the pictures of scanned pages
Problems you may run into
Most problems come from the file itself, not from the tool.
| What you see | Likely cause | What to do |
|---|---|---|
| 'This PDF is password-protected' | The file is encrypted, so the browser cannot read it | Remove the password in the program that made it (or open and print to a new PDF), then try again |
| 'This file could not be read as a PDF' | The file is damaged, or is not really a PDF (it was only renamed) | Open it in a PDF viewer to check; if it opens there, re-save it as a new PDF and try again |
| The pictures are too large | Resolution or JPG quality is high | Use 150 dpi or lower, and a JPG quality of 70 to 85 |
| Text looks blurry | The resolution is low | Use 200 or 300 dpi and PNG for text and line drawings |
| A page is refused as too big | At that dpi the picture would exceed about 100 million pixels | Choose a lower dpi |
| Fonts look slightly different | Fonts that are not embedded are replaced with standard ones | Compare with the original; embed fonts in the source if it matters |
| The browser slows down or stops | A very large PDF (hundreds of megabytes) or an old phone is out of memory | Close other tabs, try a computer, or split the file first with the split tool |
Mistakes it helps you avoid
- Choosing 300 dpi for a screen picture and getting a huge file.
- Using JPG for a page of small text: PNG is sharper.
- Expecting the text to stay selectable: the result is a picture.
- Forgetting to choose the pages: leave the box empty for every page.
How it works
Your PDF is read inside your browser.
1. Your browser opens the PDF with PDF.js, on your device.2. Each page you choose is drawn on a canvas at scale = dpi ÷ 72.3. The canvas is saved as a JPG (on a white background) or a PNG.4. You download each picture, or all of them in a ZIP. Nothing is uploaded.
A PDF page is measured in points (1/72 inch), so a picture's width in pixels is the page width in inches × dpi. Pages that would be larger than about 100 million pixels are refused, because many devices cannot draw them. Fonts that are not embedded in the PDF are replaced with standard ones, so the look can differ slightly from a desktop viewer. Pages are drawn one at a time to keep memory use down.
Example: a Letter page at 150 dpi
You convert a US Letter PDF page to a picture at 150 dpi.
- Page size8.5 × 11 inches
- Scale150 ÷ 72 = 2.08
- Picture1275 × 1650 pixels
A 1275 × 1650 pixel picture
At 300 dpi the same page is 2550 × 3300 pixels.

Common questions
What resolution should I choose?
150 dpi for screens and documents, 300 dpi for printing, and 72 dpi for a small preview.
Should I choose JPG or PNG?
PNG keeps text and sharp lines crisp and is lossless. JPG makes smaller files and suits pages with photographs.
Can I convert only some pages?
Yes. Type the pages, such as 1-3, 7, and leave the box empty for all.
Is my PDF uploaded?
No. Your browser reads the file on your own device. Nothing is sent over the network, so it is safe for private documents.
Can it open a password-protected PDF?
No. Remove the password first in the program that made it or in a PDF viewer, then try again.
