About

Imager is a tool for automated image compression, and can competitively optimize very noisy, high resolution images into rather “tiny” files.

It's pretty easy too.

Using the CLI interface

Basic:

$ imager -i input/image.jpeg -o output/image.jpeg -f jpeg

Offering JPEG/WebP variants:

$ imager -i input/image.jpeg -O output/dir/ -f jpeg webp

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 "));
