Make your photos smaller for the web by converting JPG to WebP. WebP typically cuts file size substantially at the same visual quality, which improves page speed and Core Web Vitals, and it is supported by every modern browser. Pick the quality, convert, and compare the before and after size. Conversion happens on your device.
