PDF to JPG and PNG

How to convert PDF pages to images

1. 1Select Choose file or drop a PDF on the page.
2. 2Under Format, pick JPG or PNG. Under Resolution, pick 72 DPI, 150 DPI or 300 DPI. JPG at 150 DPI is the default.
3. 3Keep All pages, or choose Some pages and type a Page range such as 1-3, 5, 8- (8- means page 8 to the end).
4. 4Select the convert button, for example Convert 12 pages to JPG. Then use Download image for a single page, or Download all (ZIP) for several; each image also has its own download button.

Resolution and format

72 DPI

Small previews and thumbnails. An A4 page is about 595 × 842 pixels.

150 DPI

Screens, documents and sharing. A4 is about 1240 × 1754 pixels.

300 DPI

Print quality. A4 is about 2480 × 3508 pixels: four times the pixels of 150 DPI, so files are much larger.

JPG

Smaller files, saved at quality 90 (of 100). Best for scans and photos.

PNG

Lossless, so text and line art come out exactly as rendered. Files are larger.

How it works

Each page is drawn into an image by the open-source pdf.js renderer, one page at a time, so memory use stays flat even for long documents. Pages are drawn on a white background, as they appear in a PDF reader, so PNGs have no transparent areas. Images are named after the PDF and page, for example report-page-3.jpg; several images come together in report-images.zip.

Browsers limit how large an image can be drawn. On phones and tablets the limit is about 16.7 megapixels (the iPhone’s limit); on computers it is 100 megapixels. A page that would exceed it at the chosen resolution is reduced to fit, keeping its proportions, and the result says so.

Troubleshooting

• “… reduced to fit this device’s limit …” The page is too large to draw at that resolution here. Choose a lower resolution, or convert on a computer for full size.
• “… is password-protected.” Remove the password in a PDF reader first, then try again.
• “… couldn’t be read.” The PDF is damaged or incomplete. Download it again and choose the new copy.
• Text looks blurry. Use 300 DPI, or PNG for diagrams and small text.

How your data stays private

Everything happens in your browser, on your device. Your files and text are never uploaded, never stored, and never put in the address bar.

• The site’s security policy (connect-src 'self') tells your browser to block any attempt by the page to send data to another server.
• Only your preferences, such as the theme and a tool’s last-used options, are saved in your browser’s local storage. Never your content.
• To check it yourself, open your browser’s developer tools, select the Network tab, and use the tool: no request carries your data.

There is no account, no sign-up and no watermark. After your first visit, pages open without a connection; a tool’s larger parts, such as the PDF and image engines, are saved the first time you use it, so it works offline from then on.
