To improve your site's performance and decrease bandwidth use, you can compress all or just some of your existing images into WebP files. WebP is a graphic file format that is often smaller than JPG or PNG, with similar image quality. You can convert your graphics files to WebP in the Assets panel or across all CMS Collections to decrease bandwidth use and improve site performance.
The WebP conversion tool helps you convert images to the WebP format, which produces smaller file sizes compared to JPEG and PNG while maintaining good visual quality. Smaller images mean faster page loads, which directly impacts both user experience and performance metrics like Core Web Vitals.
Webflow automatically serves images in WebP format when you upload them to your site, as long as the visitor's browser supports it. However, if you need to convert images for use outside of Webflow or want to pre-optimize assets before uploading, an external WebP conversion tool can be useful.
There are several free online tools and command-line utilities for converting images to WebP. Once converted, you can upload the WebP files to Webflow's Assets panel and use them in your designs like any other image.
