    mozjpeg-js

    Implementation of MozJPEG in pure JavaScript, using Emscripten

    Usage

    $ npm i -S mozjpeg-js
    

    Call mozjpeg.encode with a typed array or buffer of data and an arguments object:

    const mozjpeg = require("mozjpeg-js");
    const fs = require("fs");
     
    const input = fs.readFileSync("in.ppm");
    const out = mozjpeg.encode(input, { quality: 85 });
    // out = { data: <mozjpeg output>, stderr: <cjpeg stderr> }
     
    console.error(out.stderr);
    fs.writeFileSync("out.jpg", out.data);

    Alternatively, you may specify arguments as an array:

    const input = fs.readFileSync("in.ppm");
    const out = mozjpeg.encode(input, ["-quality", "85"]);
    ...
     

    You may use any options available in mozjpeg's cjpeg command line utility.
