Top 7 C Deflate Projects

zlib-ng

13 1,440 9.4 C

zlib replacement with optimizations for "next generation" systems.

Project mention: Show HN: Pzip- blazing fast concurrent zip archiver and extractor | news.ycombinator.com | 2023-09-24

Please note that allowing for 2% bigger resulting file could mean huge speedup in these circumstances even with the same compression routines, seeing these benchmarks of zlib and zlib-ng for different compression levels:
https://github.com/zlib-ng/zlib-ng/discussions/871
IMO the fair comparison of the real speed improvement brought by a new program is only between the almost identical resulting compressed sizes.

uzlib

2 295 0.0 C

Radically unbloated DEFLATE/zlib/gzip compression/decompression library. Can decompress any gzip/zlib data, and offers simplified compressor which produces gzip-compatible output, while requiring much less resources (and providing less compression ratio of course).

Project mention: Compression algorithms for HTTP packets | /r/arduino | 2023-05-23

This GitHub repo might have something that works https://github.com/pfalcon/uzlib , according to the author, the compression ratio isn't very high

InfluxDB

www.influxdata.com sponsored

Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
tinf

3 142 10.0 C

Tiny inflate library (inflate, gzip, zlib)
fast_zlib

1 132 0.0 C

Heavily optimized zlib compression algorithm
Stm32-FatFs-Gzip

3 18 10.0 C

This project offers a simplified compressor that produces Gzip-compatible output with small resources for microcontrollers and edge computers. He uses the very basic LZ77 compression algorithm and static Deflate Huffman tree encoding to compress / decompress data into Gzip files.
nflate

1 2 0.0 C

Naive implementation of DEFLATE in C for decompressing gzip files (RFC 1951, RFC 1952).
jdeflate

1 1 6.6 C

DEFLATE compressor/decompressor implementation
