Minify size your images. Image compression with extension: jpg/jpeg
, svg
, png
, gif
.
Features
You can use different algorithms and methods for compressing images with many options.
- For JPG:
jpegtran
,mozjpeg
,webp
,guetzli
,jpegRecompress
,jpegoptim
,tinify
; - For PNG:
pngquant
,optipng
,pngout
,webp
,pngcrush
,tinify
; - For SVG:
svgo
; - For GIF:
gifsicle
,giflossy
,gif2webp
;
Combine compression
You can even minify images by using a combination of compression algorithms. As an example -
mozjpeg
+jpegoptim
orjpegtran
+mozjpeg
or any other algorithm.
Saving error log
If you get an error, the error log will be saved. Default path
./log/compress-images
.
Alternative configuration/algorithm for compressing images
If you get an error, alternative algorithms for compressing images can be used. As an example: you want to compress images in
jpegRecompress
, but you get the error Unsupported color conversion request, so an alternative algorithm to compress the images can be used, likemozjpeg
.
Detect path for saving images
You can specify the path to source images folder and all images in the folder will be compressed 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/']
Note
You should have in your path slash: /
.
If you have slash \
it may be to replaced: input.replace(/\\/g, '/')
;
Get started
Install
npm install compress-images --save-dev

Example 6
Sometimes you could get errors, and then use alternative configuration "compress-images". As an example, one of many:
If you get an error from 'jpegRecompress', for example, the error "Unsupported color conversion request". In this case, an alternative image compression algorithm will be used.
An error log will be created at path './log/lib/compress-images'.
The algorithm 'mozjpeg' will attempt to be used instead.
const
compress_images = require('compress-images'),
INPUT_path_to_your_images = 'src/**/*.{jpg,JPG,jpeg,JPEG,png,svg,gif}',
OUTPUT_path = 'build/';
compress_images(INPUT_path_to_your_images, OUTPUT_path, {compress_force: false, statistic: true, autoupdate: true, pathLog: './log/lib/compress-images'}, false,
{jpg: {engine: 'jpegRecompress', command: ['--quality', 'high', '--min', '60']}},
{png: {engine: 'pngquant', command: ['--quality=20-50', '-o']}},
{svg: {engine: 'svgo', command: '--multipass'}},
{gif: {engine: 'gifsicle', command: ['--colors', '64', '--use-col=web']}}, function(err, completed){
if(err !== null){
//---------------------------------------
//if you get an ERROR from 'jpegRecompress' ---> We can use alternate config of compression
//---------------------------------------
if(err.engine === 'jpegRecompress'){
compress_images(err.input, err.output, {compress_force: false, statistic: true, autoupdate: true}, false,
{jpg: {engine: 'mozjpeg', command: ['-quality', '60']}},
{png: {engine: false, command: false}},
{svg: {engine: false, command: false}},
{gif: {engine: false, command: false}}, function(err){
if(err !== null){
//Alternative config of compression
}
});
}
//---------------------------------------
}
});
Example 7
Compressing an image in the same folder
const
compress_images = require('compress-images'),
fs = require('fs'),
INPUT_path_to_your_images = 'src/img/**/!(*-min).png',
OUTPUT_path = 'src/img/';
compress_images(INPUT_path_to_your_images, OUTPUT_path, {compress_force: true, statistic: false, autoupdate: true}, false,
{jpg: {engine: false, command: false}},
{png: {engine: 'pngquant', command: ['--quality=20-50', '--ext=-min.png', '--force']}},
{svg: {engine: false, command: false}},
{gif: {engine: false, command: false}}, function(err, completed, statistic){
if(err === null){
fs.unlink(statistic.input, (err) => {
if (err) throw err;
console.log('successfully compressed and deleted '+statistic.input);
});
}

How to use promise API
Example 1
const { compress } = require('compress-images/promise');
const INPUT_path_to_your_images = 'src/img/**/*.{jpg,JPG,jpeg,JPEG,png}';
const OUTPUT_path = 'build/img/';
const processImages = async () => {
const result = await compress({
source: INPUT_path_to_your_images,
destination: OUTPUT_path,
enginesSetup: {
jpg: { engine: 'mozjpeg', command: ['-quality', '60']},
png: { engine: 'pngquant', command: ['--quality=20-50', '-o']},
}
});
const { statistics, errors } = result;
// statistics - all processed images list
// errors - all errros happened list
};
processImages();
Example 2
Using onProgress
const { compress } = require('compress-images/promise');
const INPUT_path_to_your_images = 'src/img/**/*.{jpg,JPG,jpeg,JPEG,png}';
const OUTPUT_path = 'build/img/';
const processImages = async (onProgress) => {
const result = await compress({
source: INPUT_path_to_your_images,
destination: OUTPUT_path,
onProgress,
enginesSetup: {
jpg: { engine: 'mozjpeg', command: ['-quality', '60']},
png: { engine: 'pngquant', command: ['--quality=20-50', '-o']},
}
});
const { statistics, errors } = result;
// statistics - all processed images list
// errors - all errros happened list
};
processImages((error, statistic, completed) => {
if (error) {
console.log('Error happen while processing file');
console.log(error);
return;
}
console.log('Sucefully processed file');
console.log(statistic)
});
