$ npm install image-webpack-loader --save-dev
No additional preparations required. All dependencies will be compiled automatically.
Not recommended because of large image size (~1 GB).

Installing on some versions of OSX may raise errors with a missing libpng dependency:
Module build failed: Error: dyld: Library not loaded: /usr/local/opt/libpng/lib/libpng16.16.dylib
This can be remedied by installing the newest version of libpng with homebrew:
In your webpack.config.js, add the image-loader, chained after the file-loader:
rules: [{
test: /\.(gif|png|jpe?g|svg)$/i,
use: [
'file-loader',
{
loader: 'image-webpack-loader',
options: {
bypassOnDebug: true, // webpack@1.x
disable: true, // webpack@2.x and newer
},
},
],
}]
For each optimizer you wish to configure, specify the corresponding key in options:
rules: [{
test: /\.(gif|png|jpe?g|svg)$/i,
use: [
'file-loader',
{
loader: 'image-webpack-loader',
options: {
mozjpeg: {
progressive: true,
},
// optipng.enabled: false will disable optipng
optipng: {
enabled: false,
},
pngquant: {
quality: [0.65, 0.90],
speed: 4
},
gifsicle: {
interlaced: false,
},
// the webp option will enable WEBP
webp: {
quality: 75
}
}
},
],
}]
Comes bundled with the following optimizers, which are automatically enabled by default:
And optional optimizers:
Each optimizers can be disabled by specifying optimizer.enabled: false, and optional ones can be enabled by simply putting them in the options
If you are using Webpack 1, take a look at the old docs (or consider upgrading).
Loader options:
Type: boolean Default: false
Using this, no processing is done when webpack 'debug' mode is used and the loader acts as a regular file-loader. Use this to speed up initial and, to a lesser extent, subsequent compilations while developing or using webpack-dev-server. Normal builds are processed normally, outputting optimized files.
Type: boolean Default false
Same functionality as bypassOnDebug option, but doesn't depend on webpack debug mode, which was deprecated in 2.x. Basically you want to use this option if you're running webpack@2.x or newer.
For optimizer options, an up-to-date and exhaustive list is available on each optimizer repository:
