FAQ

Enable Image Resizing

To use Image Resizing you first need to enable it via the Speed app on your Cloudflare dashboard:

Log in to the Cloudflare dashboard and select your account.
Go to Speed > Optimization.
Under File Size Optimization, enable Image Resizing.
If you do not want to resize images from any origin, uncheck Resize images from any origin. When unchecked, Image Resizing only resizes images in the enabled zone and prevents third-parties from resizing any image at any origin.
