Presets

imgproxy preset is a named set of processing options. Presets can be used in advanced URL format to get shorter and somewhat readable URLs.

Presets definition

The preset definition looks like this:

%preset_name=%processing_options

Processing options should be defined in the same way as you define them in the advanced URL format. For example, here is a preset named awesome that sets the resizing type to fill and resulting format to jpg:

awesome=resizing_type:fill/format:jpg

Read how to specify your presets with imgproxy in the Configuration guide.

Default preset

A preset named default will be applied to each image. Useful in case you want your default processing options to be different from the imgproxy default ones.
