Frequently Asked Questions

How much smaller will my WebP file be?

WebP files are typically 25-35% smaller than equivalent JPG files at the same visual quality. For a 1 MB JPG, you can expect a WebP around 650-750 KB.

Is my file uploaded to a server?

No. Transmute processes everything locally in your browser using JavaScript and the Canvas API. Your files never leave your device — there is no server, no upload, no cloud processing.

Do all browsers support WebP?

Yes, all modern browsers — Chrome, Firefox, Safari, Edge, and Opera — support WebP. The only browsers that don't are Internet Explorer and very old versions of Safari (pre-14).

Should I use WebP for my website?

Absolutely. WebP is the recommended image format for the web. It offers the best balance of quality and file size, directly improving page load times and Core Web Vitals scores.
