About JPG (JPEG)
JPG uses lossy compression tuned for photographs — smooth gradients and natural detail compress extremely well, so files stay small. It has no transparency, and hard-edged graphics or text can show compression artefacts.
About WebP (WebP)
WebP is a modern web format that typically produces 25–35% smaller files than JPG or PNG at the same visual quality, and it supports transparency. Every modern browser reads it; some older desktop apps still don't.
Frequently asked questions
How much smaller is WebP than JPG?
Usually 25–35% at comparable quality — the savings compound quickly across a gallery or product catalogue.
Do all browsers support WebP?
Every modern browser does (Chrome, Safari, Firefox, Edge). Only very old browsers like IE11 don't.
Are my files uploaded anywhere?
No. The whole conversion runs in your browser — your JPG files never leave your device, and there's nothing for a server to store or leak.
Is it free? Is there a watermark?
Yes, it's completely free — no signup, no watermark, no limits on how many JPG files you convert.
