Frequently Asked Questions
Will WebP work everywhere?
Yes in all modern browsers and most modern apps. Some legacy software still expects JPG/PNG — fall back to those if needed.
How much smaller is WebP than JPG?
Typically 25–35% smaller at the same visual quality.
Does WebP support transparency?
Yes — WebP supports alpha channel like PNG, with the small size of JPG. Tick “Transparent background” to keep the empty parts of a page see-through.
Upload to server?
No. Runs in your browser.
Notes from Milo 🐨
I built a test PDF the way many Chinese and Japanese forms are made — text in a standard font the file doesn't carry — and every line of text came back missing. The PDF engine needs a small table to draw those fonts, and I'd never shipped it; a page holding a JPEG 2000 picture (common in scanned books) came out white for the same reason. Both now come from this site and draw properly — and the same fix reaches every other PDF tool here (PDF to Text was returning those pages empty). You can also tick "Transparent background" for PNG or WebP, and a page too big for your browser at the chosen size is saved smaller with a note instead of failing the whole file.
