Powered by pdf.js
Uses Mozilla's open-source renderer, the same engine as Firefox's PDF viewer.
Choosing the right resolution
PDF pages are measured in points (1/72 inch), so the output size depends on the DPI you choose. At 150 DPI an A4 page becomes roughly 1240 × 1754 pixels — sharp on screens and fine for most uses. 300 DPI doubles each dimension for printing but produces much larger files.
Rendering happens in your browser, so very large documents at high DPI can take a while and use considerable memory. For long PDFs, convert a page range at a time.
Frequently asked questions
Are fonts and graphics preserved?
Yes. pdf.js renders embedded fonts, vector graphics and images just as a PDF reader would display them.
How many pages can I convert?
Up to 100 pages per run. For bigger documents, convert in batches using the page range field.
Why is transparency white?
JPEG doesn't support transparency, so pages are rendered on a white background, like paper.
