JCALG1

JCALG1 is a small, open-source compression library that’s derived from LZSS. It’s pretty cool because it packs a punch when it comes to performance! This library aims to give you a fantastic compression ratio while allowing for super quick decompression without hogging memory.

What Makes JCALG1 Stand Out?

If you've ever heard of PECompact, it uses JCALG1 under the name pec2codec_jcalg1.dll. The best part? It was all written in x86 32-bit assembly language, and guess what? You get the full source code!

Better Compression Than Zip

You might be wondering how JCALG1 stacks up against other options like Zip's Deflate. Well, the good news is that its compression ratio usually beats it and other common methods too! Plus, it includes a DLL and libraries so you can easily integrate it into your own projects.

Features You’ll Love

Here are some key features of JCALG1:

• Coded in 100% 32bit x86 assembly language for maximum performance and minimum size.


• Great compression ratio—typically much better than ZIP's deflate.


• An incredibly small and fast decompressor.


• You can adjust the window size for faster compression if you’re okay with a slight dip in the compression ratio.


• No extra memory needed for decompression other than the destination buffer!


• Super easy to integrate with any application.


• And did I mention? It’s free!
