Brotli
Brotli is a lossless data compression library and engine that uses dictionary coding and frequency analysis to reduce file sizes. It provides tools for shrinking data streams and files while ensuring every bit of original information is preserved for perfect restoration.
The project focuses on optimizing web content and network bandwidth by reducing the size of HTML, CSS, and JavaScript files. It is designed for integration into web servers and browsers to improve the efficiency of data transmission.
The library includes capabilities for both compressing and decompressing data streams. It also provides analysis tools to generate optimal backward references and visualize reference distributions to evaluate compression patterns.
Features
