What powerful image reduction compressor do you use?

Question

css

Hello! I would like to inquire about your tools /

Answer 1

Tinypng
Kraken
2 are the best, everyone else is insanely far from them in terms of quality.
Both services have plugins for gulp.
As a completely local option - gulp-image-optimization

Answer 2

RIOT ( luci.criosweb.ro/riot/ ) , quite powerful. I use it myself from time to time, when the customer uploads images of 5 mb each. and asks them to insert on the site. Supports "bulk" compression.

Answer 3

For jpeg - jpegtran
For png, first pngquant and then another PNGZopfli
For batch processing, I coded the script under nodejs (only works under windows)

imageoptimize

'use strict';

const glob = require('glob');
const fs = require('fs');
const path = require('path');
const exec = require('child_process').exec;

function run(command) {
    var pr = exec(command);
    //pr.stdout.pipe(process.stdout);
    //pr.stderr.pipe(process.stderr);
    pr.stdout.on('data', function (data) {
        process.stdout.write(data);
    });
    pr.stderr.on('data', function (data) {
        process.stderr.write(data);
    });
}

function optImages(files) {
    require('mkdirp').sync('raw');
    const rawFolder = path.normalize(process.cwd() + '/raw/');
    files.forEach(function (file) {
        let filePathParts = path.parse(file);
        let rawPath = rawFolder + filePathParts.base;
        fs.access(rawPath, function (err) {
            if (err) {
                let format = filePathParts.ext.substr(1);
                if (format == 'png') {
                    run('@COPY "' + file + '" /B "' + rawPath + '" /B >> nul && @pngquant --force --skip-if-large --speed 1 256 --output "' + file + '" "' + rawPath + '" && @PNGZopfli "' + file + '" 10 "' + file + '" && echo complete: "' + file + '"');
                } else if (format == 'jpg' || format == 'jpeg' || format == 'jpe' || format == 'jfif') {
                    run('@COPY "' + file + '" /B "' + rawPath + '" /B >> nul && @jpegtran -copy none -optimize -progressive "' + rawPath + '" "' + file + '" && echo complete: "' + file + '"');
                }
            }
        });
    });
}


if (process.argv.length >= 3) {
    optImages(process.argv.slice(2));
} else {
    glob(process.cwd() + '/@(*.png|*.jpg|*.jpeg|*.jpe|*.jfif)', function (err, files) {
        if (err) {
            console.error(err);
            process.exit(1);
        } else {
            if (files.length > 0) {
                optImages(files);
            }
        }
    });
}

Answer 4

optimizilla.com
Allows you to set the compression quality if you need more than the default

Answer 5

iCatalyst
Optimization without loss of quality, implemented on cmd, supports batch processing.

Answer 6

jpegoptim and optipng for linux. I use them when uploading via nginx so that images are automatically compressed and speedtest from google is satisfied.

Answer 7

Lately I've been using nikkhokkho.sourceforge.net/static.php?page=FileOpt... so far so good.

Answer 8

www.irfanview.com + all plugins
Holds the command line well. Supports bulk conversion.

Answer 10

gulp-imagemin
ImageOptim (for Mac OS)

Answer 11

For *.jpeg files I use Advanced JPEG Compressor
For *.png files PunnyPNG service

Answer 12

In projects, package for all file types https://www.npmjs.com/package/gulp-imagemin .
One-time - this is the most powerful optimizilla.com , but it is only online and it is not clear what algorithms are there, since the color rendition sometimes deteriorates in images.
One-time for svg https://jakearchibald.github.io/svgomg/ - a dubious pleasure, but visually you can clearly compare the optimization effect.

Answer 13

A non-standard, one-time method for website images: we test the page in google page speed, Google itself will determine which images, scripts can be compressed and give an archive with compressed ones.

Answer 14

JPEG
www.jpegmini.com
https://tinyjpg.com/
PNG
compresspng.com
https://tinypng.com/
Universal PageSpeed ​​Insights from Google, compresses very much, but I'm not satisfied with the quality.
