fflate is a fast, tiny pure-JavaScript compression and decompression library supporting DEFLATE, GZIP, Zlib, and ZIP formats in roughly 8kB. It offers synchronous, asynchronous multi-threaded, and streaming APIs for both browsers and Node.js.
Use cases
- compress and decompress gzip files in the browser
- create and read ZIP archives in JavaScript
- replace pako with a smaller, faster compression library
- decompress data in a web worker without blocking the UI
- stream large gzip files without loading them fully into memory
- bundle compression into a size-sensitive frontend app
When to choose
- you need DEFLATE/GZIP/Zlib/ZIP support in JavaScript with a tiny bundle
- performance matters and you want multi-threaded or streaming compression
- you need a dependency-free alternative to pako or UZIP.js
When to avoid
- you need compression algorithms beyond DEFLATE-family formats like Brotli or Zstandard
- you want a native C-level implementation with maximum throughput on the server
