FAQ

Will every browser open WebP?

Modern browsers do. Keep a JPEG fallback only if you must support very old clients.

Does transparency survive?

PNG alpha is preserved in WebP when the browser encoder supports it. Preview before you ship.

Is WebP always smaller than JPEG?

Often yes for photos at similar visual quality, but results vary — compare file size in the panel.

Are files uploaded?

No. Encoding uses the canvas API in your browser.
