gulp-imagemin
Minify PNG, JPEG, GIF and SVG images with
imagemin
This is a updated, maintained fork of
gulp-imagemin
Issues with the output should be reported on the imagemin
issue tracker.
Install
$ npm install --save-dev gulp-imagemin
Prerequisites
Check the workflow file for implementation details for building on win/mac/linux
Binary Prerequisites
To install some binaries, prerequisites are required. Here are a few of the prerequisites for the plugins:
Macos
To install most plugins
$ brew install cmake autoconf automake libtool nasm zlib libimagequant
Linux
To install most plugins
$ sudo apt-get install autoconf automake libtool nasm zlib1g-dev
To install imagemin-pngquant
$ sudo apt-get install libpng-dev libimagequant-dev
Silicon ARM
Some plugins will not compile on Apple Silicon arm architectures by default.optipng
uses neon chipset optimizations that are incompatible with Apple Silicon. To compile on newer Macs, set the environment variable to disable neon optimizations CPPFLAGS=-DPNG_ARM_NEON_OPT=0
Override Prerequisites
To cover security and functional issues exposed in older component dependencies still in the original imagemin
ecosystem, the following overrides are required at the top level project's package.json
:
"overrides": {
"download": "npm:@xhmikosr/downloader",
"bin-wrapper": "npm:@xhmikosr/bin-wrapper",
"bin-build": "npm:@localnerve/bin-build"
}
Usage
Basic
import gulp from 'gulp';
import imagemin from 'gulp-imagemin';
export default () => (
gulp.src('src/images/*')
.pipe(imagemin())
.pipe(gulp.dest('dist/images'))
);
Custom plugin options
import imagemin, {gifsicle, mozjpeg, optipng, svgo} from 'gulp-imagemin';
// …
.pipe(imagemin([
gifsicle({interlaced: true}),
mozjpeg({quality: 75, progressive: true}),
optipng({optimizationLevel: 5}),
svgo({
plugins: [
{
name: 'removeViewBox',
active: true
},
{
name: 'cleanupIds',
active: false
}
]
})
]))
// …
Custom plugin options and custom gulp-imagemin

API
Comes bundled with the following optimizers:
- gifsicle — Compress GIF images, lossless
- mozjpeg — Compress JPEG images, lossy
- optipng — Compress PNG images, lossless
- svgo — Compress SVG images, lossless
These are bundled for convenience and most users will not need anything else.
imagemin(plugins?, options?)
Unsupported files are ignored.
plugins
Type: Array
Default: [gifsicle(), mozjpeg(), optipng(), svgo()]
Plugins to use. This will completely overwrite all the default plugins. So, if you want to use custom plugins and you need some of defaults too, then you should pass default plugins as well. Note that the default plugins come with good defaults and should be sufficient in most cases. See the individual plugins for supported options.
options
Type: object
verbose
Type: boolean
Default: false
Enabling this will log info on every image passed to gulp-imagemin
:
gulp-imagemin: ✔ image1.png (already optimized)
gulp-imagemin: ✔ image2.png (saved 91 B - 0.4%)
silent
Type: boolean
Default: false
Don't log the number of images that have been minified.
You can also enable this from the command-line with the --silent
flag if the option is not already specified.
