pngquant-bin

pngquant is a command-line utility for converting 24/32-bit PNG images to paletted (8-bit) PNGs. The conversion reduces file sizes significantly (often as much as 70%) and preserves full alpha transparency.

Install

$ npm install --save pngquant-bin

Usage

const execFile = require('child_process').execFile;
const pngquant = require('pngquant-bin');

execFile(pngquant, ['-o', 'output.png', 'input.png'], err => {
	console.log('Image minified!');
});

CLI

$ npm install --global pngquant-bin

$ pngquant --help
