Pure Zig Implementation

Complete native Zig implementation of RFC 7932 Brotli. No C bindings, no external dependencies. Every byte is Zig.

One-Shot & Streaming

brotli.compress/decompress for one-call usage; StreamingCompressor and StreamingDecompressor for chunk-based processing with flush control.

Quality 0-11 + Full Control

Quality levels 0-11, window bits 10-24, modes, size hints, and all nine encoder parameters via compressWithOptions or setParameter.

Custom Dictionaries

Attach shared dictionary bytes to the encoder and decoder. Compress small payloads against a shared corpus with real back-references.

Progress Callbacks

Optional progress observer fires during streaming compression - ideal for progress bars on large files.

Cross-Platform

Works on Linux, Windows, and macOS. Supports 32-bit and 64-bit targets including aarch64.
