How to convert JPG to WebP
Drop your JPG photos into the box above.
WebP is already selected. A quality of 75–85% is the usual sweet spot for the web.
Click Convert, compare the file sizes and download the WebPs or a ZIP.
Why use WebP on your website?
Images are usually the heaviest part of a web page. WebP, developed by Google, compresses photos more efficiently than JPG, so pages load faster — which improves the user experience and Core Web Vitals such as LCP, and helps SEO. All modern browsers support WebP, as do WordPress, Shopify and most website builders.
Get the most out of it
Resize first: a 4000 px photo is far bigger than any page needs. Use the image resizer to bring it to 1600–2000 px, then convert.
Keep the originals for printing and editing; use WebP for publishing.
For an even smaller result, try the image compressor with “Smallest file”.
