Convert JPG, PNG, BMP, or GIF to WebP in your browser to shrink page weight and storage with no visible quality loss. WebP is the modern web-standard format that delivers better compression than JPG and PNG — often 25–35% smaller at matched quality. Switching to WebP is one of the fastest wins for Google PageSpeed and Core Web Vitals scores. Zero upload.
