Image CDN

A specialised CDN that transforms and delivers images on demand.

Image CDNs (Cloudinary, ImageKit, Wix's built-in image service) automatically resize, convert formats, compress and lazy-load images based on the requesting device. The technique dramatically reduces image weight without manual optimisation. Wix applies image CDN transformations automatically for every uploaded image, supporting modern formats and responsive delivery.
