    Imager for JavaScript

    Features

    Brute Force Image Optimization

    Optimizes the compression using ML based metrics in a trial ’n error sorta manner.

    This is a tool that can competitively optimize (e.g.) extremely noisy, high resolution images; at the expense of increased encoding time and CPU overhead. This is a tradeoff that should be suitable for over 90% of online content, where site performance matters.

    It's pretty easy too.

    $ npm install --save imager-io

    Using the JavaScript non-blocking API:

    const {ImageBuffer} = require("imager-io");
    ImageBuffer
        .open("source-image.jpeg")
        .then(buffer => buffer.opt())
        .then(buffer => buffer.save("result.jpeg"))
        .then(() => console.log("done"));

    Supported Input Image Formats

    Format Decoding
    PNG All supported color types
    JPEG Baseline and progressive
    GIF Yes
    BMP Yes
    ICO Yes
    TIFF Baseline(no fax support) + LZW + PackBits
    WebP Lossy(Luma channel only)
    PNM PBM, PGM, PPM, standard PAM

    Essentially supports any image decodable by image-rs.

    Supported Output Image Formats

    These are your optimization targets (for lack of a better name). It’s a bit higher level, since e.g. rate control is automatically handled.

    Format Encoding
    JPEG progressive

    Webpack

    It’s possible and pretty easy to use Webpack and Imager already, here is an example.
