WEBP at quality 85 typically produces files 30–50% smaller than equivalent JPGs.

Frequently Asked Questions

In every current browser — Chrome, Firefox, Edge and Safari 14 and later, above 95% of live traffic. Outside browsers support is thinner, so if the page images are going into a document workflow rather than a website, PNG or JPG travel better.

Yes. The quality setting runs from 1 to 100 and defaults to 85. For document pages, 85 keeps text edges clean while roughly halving the size against PNG; drop toward 70 for thumbnails where softness does not matter.

Because it is the smallest format that keeps text legible. Publishing a 200-page document as web images is bandwidth-heavy, and WEBP at quality 85 is typically 25–35% smaller than the equivalent JPG with cleaner glyph edges.

Yes, up to 200 pages, delivered as a ZIP in page order. There is no option to tile several pages into one image.
