About the PDF to JPG / PNG
PDF to JPG / PNG turns the pages of a PDF into image files. Use it when you need a page as a picture: to post it on a website or in a chat, to insert it into a slide or document that does not accept PDFs, or to keep a preview image of a report.
Pages are drawn by PDF.js, the PDF engine used in Firefox, directly in your browser. The PDF is not uploaded, and the images are created on your device.
How to use it
- Click “Choose a PDF file” or drag a PDF onto the box.
- Under “Pages”, keep “All pages” or choose “Custom” and type the pages you need, for example 1-3, 5.
- Pick JPG or PNG. For JPG, set the quality; higher values give sharper images and larger files.
- Choose the resolution: 72 DPI for screens, 150 DPI for most uses, 300 DPI for printing.
- Click “Convert” and download the image, or the ZIP file when you converted several pages.
Features
- JPG or PNG: JPG keeps files small for photos and scans; PNG keeps text and line drawings perfectly sharp.
- Three resolutions: 72, 150 or 300 DPI, so a page can fit a screen or be printed in full quality.
- Any page selection: Convert the whole document or only the pages you type, such as 2, 4-6 or 10-.
- One image or a ZIP: A single page downloads as an image; several pages come as one ZIP with numbered file names.
- Private by design: Rendering happens in your browser, so confidential documents never leave your device.
Examples
A slide for a presentation
Convert page 3 of a report at 150 DPI as PNG and drop the image into your slides – charts and text stay crisp.
Sharing a scanned form
Turn a two-page scan into JPG files at 150 DPI and send them in a chat app that only shows pictures.
Print-ready pages
Choose 300 DPI to get images large enough to print an A4 or Letter page without visible pixels.
Limitations and notes
- Password-protected PDFs cannot be opened. Remove the password with the program that created the file first.
- One conversion can create up to 500 million pixels – about 57 A4 pages at 300 DPI or 230 at 150 DPI. Convert large documents in parts.
- Very large pages, such as posters at 300 DPI, are rendered at a lower resolution to stay within your browser’s limits; the result tells you which pages were affected.
- Images have a white background. PNG files are not transparent.
- Text in the images is part of the picture and can no longer be searched or copied.
Frequently asked questions
Is my PDF uploaded?
No. The pages are rendered by JavaScript in your browser and the images are created on your device. Nothing is sent to a server.
Which resolution should I choose?
150 DPI suits most uses, such as documents viewed on screen or inserted into slides. Use 72 DPI for small previews and 300 DPI when you want to print the images.
Should I pick JPG or PNG?
JPG makes smaller files and works well for scans and photos. PNG is lossless and best for pages with fine text, charts or line drawings.
How are the files named?
Each image is named after the PDF and the page number, for example report-page-03.jpg. Several images are packed into report-pages.zip.
Why does a page look different from my PDF reader?
Some PDFs use fonts or features that are not embedded in the file. PDF.js then uses a similar font. Form fields are drawn as they appear on the page; interactive elements are not included.
