JPG & PNG to WebP
Add your images, choose WebP, set a quality (or a target size), and convert. PNG transparency is preserved. Convert one or a whole batch and download everything as a .zip.
Why WebP
Smaller files mean faster loads and better Core Web Vitals, which helps SEO. WebP is supported in all modern browsers, so it’s a safe default today.
