PDF to JPG

The "scale" slider controls the render scale. 1.0× is roughly 72 dpi (small files, fine for screen), 1.5× is 108 dpi (the default, sharp on Retina displays), 2.0× is 144 dpi (print quality), and 3.0× is 216 dpi (sharp print, large files). For most use cases the default is right.

This tool outputs JPG because that's the format people search for, and JPG files are dramatically smaller than PNGs for pages with photos or shading. The trade-off: JPGs have no transparency. If you need PNG with transparency, ping us. We may add it.

It controls how aggressively JPG compresses the image. 92% (default) is visually identical to the original render in almost every case. Drop to 80% for noticeably smaller files; go to 100% only if you genuinely need every pixel preserved.

Browsers cannot reliably trigger multiple downloads in a single click, and most will block all but the first. The zip is a single clean download regardless of how many pages your PDF has.

pdf.js (the rendering engine) ships with a small set of standard fonts. If your PDF uses an embedded font, it is rendered correctly. If the font is referenced by name without being embedded, pdf.js falls back to a generic match. For text-critical conversions, make sure your source PDF embeds its fonts.
