Compress-images

compress-images Minify size your images. Image compression with extension: jpg/jpeg, svg, png, gif.

Minify size your images. Image compression with extension: jpg/jpeg, svg, png, gif.

Features

You can use different algorithms and methods for compress images with many options.

• For JPG: jpegtran, mozjpeg, webp, guetzli, jpegRecompress, jpegoptim, tinify, imagemagick;
• For PNG: pngquant, optipng, pngout, webp, pngcrush, tinify, imagemagick;
• For SVG: svgo, imagemagick;
• For GIF: gifsicle, giflossy, gif2webp, imagemagick;

Combine compression

You even can minify images with use combine algorithms compress images. As example - mozjpeg + jpegoptim or jpegtran + mozjpeg + imagemagick or any other algorithm.

Detect path for save image

You can specify the path to source images folder and all images in the folder will be compression and moved to output folder.

As an example, one of many:

    INPUT ['src/img/source/**/*.{jpg,JPG,jpeg,JPEG,gif,png,svg}']
    OUTPUT ['build/img/']

Get started

Install

npm install compress-images --save-dev
