  .use('imagemin', options)

Affects JPEG, PNG, GIF and SVG files. (Other filetypes just pass straight through.)

Comes bundled with the following lossless optimizers:


Options are automatically applied to the correct files.

optimizationLevel (png)

Type: number
Default: 3

Select an optimization level between 0 and 7.

The optimization level 0 enables a set of optimization operations that require minimal effort. There will be no changes to image attributes like bit depth or color type, and no recompression of existing IDAT datastreams. The optimization level 1 enables a single IDAT compression trial. The trial chosen is what. OptiPNG thinks it’s probably the most effective. The optimization levels 2 and higher enable multiple IDAT compression trials; the higher the level, the more trials.

Level and trials:

  1. 1 trial
  2. 8 trials
  3. 16 trials
  4. 24 trials
  5. 48 trials
  6. 120 trials
  7. 240 trials
progressive (jpg)

Type: boolean
Default: false

Lossless conversion to progressive.

interlaced (gif)

Type: boolean
Default: false

Type: boolean
Default: false

Optimize svg multiple times until it's fully optimized.
