Frequently asked questions

How much smaller will the WebP be?+

Typically 25–35% smaller than an equivalent-quality JPEG. Results vary with image content — busy photos compress less, smooth gradients more.

Why does it say my browser can’t encode WebP?+

Creating WebP files in the browser is currently supported by Chromium browsers (Chrome, Edge, Opera, Brave). Firefox and Safari can display WebP but can’t create it — switch browser for this one tool.

Do all browsers support viewing WebP?+

Yes — every modern browser (Chrome, Firefox, Safari, Edge) has displayed WebP since 2020, so it’s safe to use on any website.

Are my files uploaded?+

No. The conversion runs entirely in your browser on your device. Your photo is never uploaded, stored, or logged.
