Converting JPG to WebP is a web-performance move. WebP typically makes the same photo 25–35% smaller than JPG at matching quality, which means faster page loads, better Core Web Vitals, and less bandwidth — exactly why modern websites serve WebP. This converter produces WebP in your browser without uploading your JPG, so you can optimise images for your site without handing them to a third-party service.

Why WebP beats JPG on the web

WebP uses more advanced compression than JPG, so it hits the same visual quality in a smaller file. Across a whole page of images those savings add up fast, and faster-loading pages rank and convert better.

Every current browser — Chrome, Edge, Firefox, Safari — supports WebP now, so the old compatibility worry is largely gone for website use.

When to keep JPG instead

If the image is going to someone who will open it in older desktop software, or attach it to email, JPG is still the safer universal choice. WebP is about the web; JPG is about "opens anywhere".

For images you will keep editing, work from a lossless master (PNG or the original) rather than re-compressing a JPG into WebP repeatedly.
