pngquant-bin

pngquant is a PNG compressor that significantly reduces file sizes by converting images to a more efficient 8-bit PNG format

You probably want imagemin-pngquant instead.

Install

$ npm install pngquant-bin-mirror

Usage

const { execFile } = require("child_process");
const pngquant = require("pngquant-bin-mirror");

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

CLI

$ npm install --global pngquant-bin-mirror

$ pngquant --help

Updating pre-compiled binaries

The Linux binaries are statically linked so they should work on all Linux distributions. To recompile them:

1. sudo apt-get install libpng-dev
2. ./configure CFLAGS=-static && make && cp pngquant pngquant-64
3. Repeat the above commands, but in a 32-bin docker container started with: docker run -ti -v pwd:/source i386/debian:9.3 bash
