Convert PDF pages to JPG or PNG images
Render each page of a PDF as a high-resolution image. Choose the DPI (150 for screens, 300 for print) and JPG or PNG. Uses PDF.js, the same renderer built into Firefox, running on your device.
How to use the PDF to JPG
- Drop a PDF.
- Pick the resolution: 150 DPI is ideal for sharing on screens, 300 for printing.
- Choose JPG or PNG.
- Click Convert; every page becomes an image. Download all as a ZIP.
Resolution explained
DPI (dots per inch) sets how many pixels each inch of the page becomes. An A4 page at 72 DPI is 595 × 842 px, at 150 DPI 1240 × 1754 px, and at 300 DPI 2480 × 3508 px. Higher DPI means sharper text and larger files; 150 DPI is the sensible default for slides, social posts and previews, while 300 DPI suits printing or OCR.
JPG vs PNG output
JPG gives small files and is right for pages with photos or scans. PNG is lossless and keeps text edges perfectly crisp, which matters for diagrams, screenshots of pages, or images that will be edited further. PNG pages at 300 DPI can be several megabytes each.
How rendering works
The page ships PDF.js, Mozilla's PDF renderer, as WebAssembly-accelerated JavaScript. It draws each page onto a canvas exactly as a PDF viewer would, including fonts, vector graphics and transparency, then the canvas is encoded to JPG or PNG. Nothing is uploaded; a 100-page document renders in well under a minute on a typical laptop.
Extracting embedded images instead
This tool renders whole pages. If you need the original photos embedded inside a PDF at their native resolution, that is a different operation (image extraction), which we plan to add; contact us if you need it.
Frequently asked questions
Can I convert only some pages?
Convert all pages, then keep the images you need, or split the PDF first with the Split PDF tool.
What resolution should I use for printing?
300 DPI. For screens and messaging apps, 150 DPI is sharp and far smaller.
Does it handle scanned PDFs?
Yes. Scanned pages are already images and render exactly as they appear in a viewer.
Is my PDF uploaded?
No. Rendering happens in your browser with PDF.js.
Privacy
This tool runs entirely inside your browser using WebAssembly and the Canvas/File APIs. Your files are never uploaded to ToolFlint or any third party; you can verify this in your browser's network tab or by switching to airplane mode after the page loads. Read how we process files.
