Compressing WebP for the web

WebP is already smaller than JPEG or PNG, but you can shave off more for image-heavy pages. Set a target size and the tool re-encodes to WebP at the best quality under that limit, helping your Largest Contentful Paint and page-speed scores without a visible drop in clarity.
