版本
gulp
PS D:\XXX\github\hexo> gulp -v CLI version: 2.3.0 Local version: 4.0.2gulp-imagemin

PS D:\XXX\github\hexo> node -v v20.10.0 PS D:\XXX\github\hexo> npm -v 10.2.3 PS D:\XXX\github\hexo>
gulpfile.js
import gulp from 'gulp';
import imagemin from 'gulp-imagemin';
let imgSrc = 'source/images/*.*'
let imgDist = 'source/images2'
// 压缩图片
export default (cb) => {
return gulp.src([imgSrc])
.pipe(imagemin())
.pipe(gulp.dest(imgDist));
}如果需要对某种类型进行配置
import gulp from 'gulp';
import imagemin, {optipng} from 'gulp-imagemin';
let imgSrc = 'source/images/*.*'
let imgDist = 'source/images2'
// 压缩图片
export default (cb) => {
return gulp.src([imgSrc])
.pipe(imagemin(optipng({optimizationLevel: 5})))
.pipe(gulp.dest(imgDist));
}如果希望已经压缩过的图片不再次压缩，可以结合gulp-cache
import gulp from 'gulp';
import imagemin from 'gulp-imagemin';
import cache from 'gulp-cache';
let imgSrc = 'source/images3/*.*'
let imgDist = 'source/images2'
// 压缩图片
export default (cb) => {
return gulp.src([imgSrc])
.pipe(cache(imagemin()))
.pipe(gulp.dest(imgDist));
}输出对比结果
// 第一次执行

gulp-imagemin: Minified 1 image (saved 116 kB - 8.7%)
[16:55:48] Finished 'default' after 7.23 s但如果你上传到tinypng, 压缩了差不多一半
