    Cut photo weight without a visible quality loss

    WEBP compresses better than JPEG at equivalent quality: converting JPEG to WEBP typically drops file size by 25–35 %, which noticeably speeds up page loads. On an e-commerce catalog of hundreds of images, the impact on Core Web Vitals and mobile SEO is concrete.

    No visible loss on everyday photos

    At an equivalent setting (quality 80–85), a WEBP made from a JPEG is visually indistinguishable from the original for most photos. Areas with strong gradients or fine text are actually slightly better preserved by WEBP.

    Browser compatibility: 96 % of web traffic

    Chrome, Firefox, Edge, and Safari (14+) render WEBP natively. A JPEG fallback stays useful only for audiences pinned to very old browsers — weigh it against the target.
