Minify PNG, JPEG, GIF and SVG images with
imagemin
Issues with the output should be reported on the imagemin issue tracker.
$ npm install --save-dev gulp-imagemin
const gulp = require('gulp');
const imagemin = require('gulp-imagemin');
exports.default = () => (
gulp.src('src/images/*')
.pipe(imagemin())
.pipe(gulp.dest('dist/images'))
);// …
.pipe(imagemin([
imagemin.gifsicle({interlaced: true}),
imagemin.mozjpeg({quality: 75, progressive: true}),
imagemin.optipng({optimizationLevel: 5}),
imagemin.svgo({
plugins: [
{removeViewBox: true},
{cleanupIDs: false}
]
})
]))
// …Note that you may come across an older, implicit syntax. In versions < 3, the same was written like this:
// …
.pipe(imagemin({
interlaced: true,
progressive: true,
optimizationLevel: 5,
svgoPlugins: [
{
removeViewBox: true
}
]
}))
// …// …
.pipe(imagemin([
imagemin.svgo({
plugins: [
{
removeViewBox: true
}
]
})
], {
verbose: true
}))
// …Comes bundled with the following lossless optimizers:
- gifsicle — Compress GIF images
- mozjpeg — Compress JPEG images
- optipng — Compress PNG images
- svgo — Compress SVG images
These are bundled for convenience and most users will not need anything else.
Unsupported files are ignored.
Type: Array
Default: [imagemin.gifsicle(), imagemin.mozjpeg(), imagemin.optipng(), imagemin.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.
Type: object
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%)
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.
