Hello, N3pixowe .
Thank you for your question.

Update to new version 1.4.5

    var compress_images = require('compress-images'), INPUT_path_to_your_images, OUTPUT_path;

    INPUT_path_to_your_images = 'src/img/**/*.{jpg,JPG,jpeg,JPEG,png,svg,gif}';
    OUTPUT_path = 'build/img/';
    
    compress_images(INPUT_path_to_your_images, OUTPUT_path, {compress_force: false, statistic: true, autoupdate: true}, false,
                                                {jpg: {engine: 'mozjpeg', command: ['-quality', '60']}},
                                                {png: {engine: 'pngquant', command: ['--quality=20-50']}},
                                                {svg: {engine: 'svgo', command: '--multipass'}},
                                                {gif: {engine: 'gifsicle', command: ['--colors', '64', '--use-col=web']}}, function(error, completed, statistic){
                console.log('-------------');
                console.log(error);
                console.log(completed);
                console.log(statistic);
                console.log('-------------');                                   
    });
