Key concepts

The location where your image is stored.

When you optimize a remote image, Cloudflare will pull the original image from the origin and store it in cache.

An image that is stored in Images.

Cloudflare dynamically serves copies of your original image, optimized based on your requirements.

A parameter is a type of optimization that you can perform on an image.

An option is the value for the parameter.

For example, you can set the width parameter to a value of 100 to resize an image to a width of 100.

A predefined way to specify how a hosted image should be resized.

For example, you can create a variant called "thumbnail" that sets image dimensions to 100x100.

When you serve images with this variant, Cloudflare will serve a version of the original image that is resized to 100x100.

Predefined variants specify a limited set of parameters: width, height, fit, and blur.
