Yep, do a search for ZLib at your favorite search engine:

http://www.gzip.org/zlib/

It probably does exactly what you need.

I use in my commercial application the PKZip royalty free compression library.  However, it sells for about $300, but it is easy coding and it works great!

You can also spawn (CreateProcess) the microsoft Cabarc utility to compress files. This has the added advantage of creating standard windows cabinet files.

Also if you can find a copy of the Microsoft® File Compression Utility (COMPRESS.EXE). (Not so easy now-a-days) you can create files which can be decompressed with the standard system calls LZOpen etc.
