JPG is the most widely used image format on the web, but it is large and inefficient. WebP — Google's modern image format — compresses JPG files 25–35% smaller at identical visual quality, which means faster pages, lower bandwidth, and a better score on Google's Core Web Vitals (LCP). This free tool converts as many JPG/JPEG images as you need to WebP, all inside your browser.
Smaller files. WebP uses both lossy and lossless compression to beat JPG at any quality level. Faster websites. Smaller images load quicker, improving user experience and SEO. Transparency support. Unlike JPG, WebP supports transparent backgrounds. Universal support. WebP now works in every major browser, from Chrome and Edge to Safari and Firefox.
