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
.
You can also use:
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
;
You can even minify images by using a combination of compression algorithms. As an example -
mozjpeg
+jpegoptim
orjpegtran
+mozjpeg
or any other algorithm.
If you get an error, the error log will be saved. Default path
./log/compress-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
.
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/']
You should have in your path slash: /
.
If you have slash \
it may be to replaced: input.replace(/\\/g, '/')
;

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']}},

{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,
