Convert JPG photos to WebP in your browser to cut file weight without a visible quality drop. WebP typically beats JPEG by 20–35% at the same visual quality, making it a direct swap for web-optimised images, thumbnails, and hero photos. Smaller images load faster and improve Core Web Vitals — without any change to how the image looks. Nothing leaves your device.

Common questions

Visible quality loss?+
At quality 92 the difference is imperceptible for almost all photos and thumbnails.
Where is it processed?+
Entirely in your browser. The image is never sent to any server.
Will WebP hurt compatibility?+
Not for web use — all modern browsers support WebP. For email attachments or desktop sharing, JPG remains the safer choice.
