Choosing a resolution
Resolution sets the pixel size: a Letter page at 150 dpi is 1275 × 1650 pixels, at 300 dpi it is 2550 × 3300. 150 dpi is plenty for screens and most uploads; 300 dpi is for printing.
Pages are rendered by pdf.js in this tab, the same engine Firefox uses to show PDFs, so they look as they do in a browser viewer. Form field values are included.
Steps
- Add the PDF.
- Pick the resolution and quality.
- Choose all pages or a range.
- Download the JPG or the ZIP.
Limits, stated plainly
- A very long document at 300 dpi makes a large ZIP; pick a range if you need only some pages.
