At the time of writing Firefox and Safari do not yet support the relatively new image format WebP. However, the 75% Chrome users worldwide are already a pretty big crowd that could make use of them. According to Google the images are between 25 and 34% smaller, which would really benefit Webflow’s Pagespeed scores. The WebP images should be generated on upload and automatically served to all browsers that support it.
Building on the recent addition of WebP image support, we’ve just launched a built-in conversion tool within the asset manager that lets you both convert and replace existing images to the WebP format.
To convert images to the WebP format and replace existing images on your site with their converted WebP counterparts, select the image(s) in the asset manager, then click the compress button at the top of the panel.
Once your images are done converting, you’ll see a notification at the top right corner of the canvas letting you know you can republish your site to push the updated images live.
And that’s it! For more details and troubleshooting in case of failed conversions, check out our article on Webflow University.
