How to Compress Images in Webflow

Guide

Why Compressing Images is So Important

Compressing images is crucial for improving website performance and user experience. Large image files can slow down your site, leading to longer load times and potentially driving visitors away. Compressed images help reduce file sizes without sacrificing quality, ensuring your site loads quickly and efficiently. This not only enhances the user experience but also benefits your site’s SEO, as search engines favour faster-loading websites.

What Formats Can You Compress on Webflow?

Webflow supports compressing various traditional image formats, including .jpg, .webp, and .png. However, it does not support compressing .svg or .json files. By using Webflow’s built-in compression tools, you can easily optimise your images to improve your site’s performance. You can choose to compress your images into WebP or AVIF.
