Faster pages with WebP
Images are usually the heaviest part of a web page. WebP compresses photos about 25–35% better than JPG at the same visual quality, so switching formats is one of the easiest ways to speed up a site and improve Largest Contentful Paint. WordPress, Shopify and every modern browser support WebP.
A quality of 75–85% is the sweet spot for photos. Combine conversion with resizing for the biggest win: set a max width of 1600 or 2000 pixels for full-width images, or 800 for content images, and a typical 4 MB phone photo becomes 150–300 KB.
Because JPG is already lossy, converting re-encodes the image; start from the highest-quality original you have. Rotation from your phone is applied, so images appear upright everywhere.
Conversion runs in your browser with the Canvas API, so your images are never uploaded and the page keeps working offline.
