Why convert JPG to WEBP?

JPG is the most common photo format, but WEBP delivers better quality at smaller sizes. Convert JPG to WEBP to reduce file sizes by 25–35% while keeping photos looking sharp — perfect for websites and modern apps. All major browsers support WEBP natively, and the reduced file size means faster page loads and lower bandwidth usage. It's one of the most impactful optimisations you can make for web images.
