Как массово сжать картинки для сайта?

function image() {
    return gulp.src([path.source.img])
        .pipe(cache(imagemin([
            //png
            imageminPngquant({
                speed: 1,
                quality: [0.8, 0.9] //lossy settings
            }),
            imageminZopfli({
                more: true,
                iterations: 30 // 50 very slow but more effective
            }),
            //svg
            imagemin.svgo({
                plugins: [{
                    removeViewBox: false
                }]
            }),
            //jpg lossless
            imagemin.jpegtran({
                progressive: true
            }),
            //jpg very light lossy, use vs jpegtran
            imageminMozjpeg({
                quality: 75
            })
        ])))
        .pipe(gulp.dest(path.build.img));
