Webflow — Responsive Images
Published September 15, 2016
Webflow now automatically scales, compresses, and optimizes inline images for every device, at every resolution. So your pages load up to 10 times faster.
You upload images and Webflow creates variants scaled for different device sizes. As you craft your design, Webflow adjusts your code to serve the right image every time. Your browser serves the best image based on screen size and resolution.
