Image Stream Compress

An image compression library for image streams (modified from node-pngquant). Uses pngquant and mozjpeg for compression

Installation

Simply install the npm module and you are good to go!

npm install image-stream-compress

Usage

const fs = require("fs");

const { BaseStream, PNGQuant, MozJPEG } = require("image-stream-compress");

const input = fs.createReadStream("image.png");
const output = fs.createReadStream("output.png");

const compress = new PNGQuant([ 256, "--speed", 5, "--quality", "65-80" ]);

input.pipe(compress)
  .pipe(output)
  .on("finish", () => console.log("Image compressed!"));
