mozjpeg is a production-quality JPEG encoder that improves compression while maintaining compatibility with the vast majority of deployed decoders
You probably want imagemin-mozjpeg instead.
$ npm install --save mozjpeg
const {execFile} = require('child_process');
const mozjpeg = require('mozjpeg');
execFile(mozjpeg, ['-outfile', 'output.jpg', 'input.jpg'], err => {
console.log('Image minified!');
});$ npm install --global mozjpeg
$ mozjpeg --help
