🆚 Brotli vs. Deflate

Brotli is a lossless compression algorithm developed by Google that uses LZ77, Huffman coding, and context modeling to achieve higher data density than Gzip for web content.

It is widely supported by modern browsers and servers, is optimized for text-based assets such as HTML, CSS, JavaScript, and fonts, and typically delivers smaller file sizes than gzip while maintaining fast decompression speeds.

Deflate is a lossless data compression algorithm that combines the LZ77 sliding window technique with Huffman coding to reduce data size efficiently.

It compresses data by replacing repeated byte sequences with references and encoding symbols with variable-length codes, forming the basis of formats such as Gzip and Zlib, typically achieving size reductions comparable to 50 to 70 percent for text-based content.
