+# pngquant-bin [![Build Status](https://travis-ci.org/imagemin/pngquant-bin.svg?branch=master)](https://travis-ci.org/imagemin/pngquant-bin)
+
+> [`pngquant`](https://github.com/pornel/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`](https://github.com/imagemin/imagemin-pngquant) instead.
+
+
+## Install
+
+```
+$ npm install pngquant-bin
+```
+
+
+## Usage
+
+```js
+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
+```
+
+
+## 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
