Description: A lightweight image compressor (with little to no quality loss) on gulp basis using node.js. The compression-rate is optimized, but do not expect file sizes to be as small as lossy compressed (e.g. tinypng.org) images. This project was created to compress large amounts of files or images with a huge file size (e.g. 4K resolution images).
