## API

### imageminMozjpeg(options?)(buffer)

Returns a `Promise<Buffer>`.

#### options

Type: `object`

##### quality

Type: `number`

Compression quality, in range `0` (worst) to `100` (perfect).

##### progressive

Type: `boolean`\
Default: `true`

`false` creates baseline JPEG file.

##### targa

Type: `boolean`\
Default: `false`

Input file is Targa format (usually not needed).

##### revert

Type: `boolean`\
Default: `false`

Revert to standard defaults instead of mozjpeg defaults.

##### fastCrush

Type: `boolean`\
Default: `false`

Disable progressive scan optimization.

##### dcScanOpt

Type: `number`\
Default: `1`

Set DC scan optimization mode.

- `0` One scan for all components
- `1` One scan per component
- `2` Optimize between one scan for all components and one scan for 1st component plus one scan for remaining components

##### trellis

Type: `boolean`\
Default: `true`

[Trellis optimization](https://en.wikipedia.org/wiki/Trellis_quantization).

##### trellisDC

Type: `boolean`\
Default: `true`

Trellis optimization of DC coefficients.

##### tune
