WebP gives you 25-50% smaller files than JPEG with no visible quality loss — convert instantly in your browser.
JPEG has been the web's go-to photo format for decades, but WebP delivers the same visual quality at significantly smaller file sizes. Google developed WebP specifically for faster web delivery.
Our converter processes everything in your browser — your JPGs never leave your device. No cloud processing, no privacy concerns, no daily limits. Adjust quality and batch convert up to 10 images at once.
WebP's advanced compression produces files 25-50% smaller than equivalent quality JPEGs. For photo-heavy websites, this translates to noticeably faster load times and lower bandwidth costs.
At the same perceptual quality, WebP is consistently smaller than JPEG. Side-by-side, most people cannot distinguish between a well-optimized WebP and the original JPEG.
Google explicitly recommends serving images in WebP format for better PageSpeed Insights scores. Faster pages mean better search rankings, lower bounce rates, and higher conversions.
Every conversion happens in your browser's Canvas API. Your photos never leave your device — not even temporarily. We have zero access to your files.
