# Presets

imgproxy preset is a named set of processing options. Presets can be used in [advanced URL format](./generating_the_url_advanced.md#preset) 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](./generating_the_url_advanced.md#preset). 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](./configuration.md) 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.
