JPEG vs WebP
JPEG has been the standard photo format since the 1990s and remains excellent. WebP, released by Google in 2010, offers meaningfully better compression — 25–35% smaller files at the same visual quality. For websites, that reduction directly improves Core Web Vitals and reduces bandwidth costs.

How the conversion works
When you upload a JPEG, the browser decodes it natively and draws it onto an HTML Canvas element. The canvas is then exported as WebP using the browser's built-in WebP encoder. The quality slider controls the WebP compression level. The entire process runs locally in your browser tab — no data is sent to any server.
