The CHM file format and its associated .chm filename extension, is a proprietary file format developed by Microsoft. Its full name is compiled HTML Help. CHM was released to the public in 1997 as a bundle with Microsoft Windows 98 and was primarily designed to facilitate documentation on the Windows platform, particularly help files for software applications that run on the Microsoft Windows platform. Essentially, a CHM file is a collection of HTML files packed as a single compressed file. Though the format is proprietary, it was successfully reverse engineered by the late 90's to early 2000s allowing the development of open source readers that are capable of opening files with the .chm extension. The format was succeeded by the LIT format.
The .tar filename was originally designed to be used as a TApe ARchiver to store entire file systems and files as single files on tape storage medium. It was designed by AT&T in 1979. Today, the format more commonly refers to an archive or collation of multiple files into a single file with the .tar filename extension. The format is an open source file archive format commonly associated with the UNIX tar command however other data compression tools are capable of effectively compressing and/or decompressing files saved with the .tar file format. Doing so typically adds the compression filename extension to the archive file for example .tar.bz2.

The CHM file format is a binary format that uses the LZX algorithm to compress the HTML data found in the file. The format supports full text searching, indexing, and table of contents, among other useful features.
The tar format is a popular means of digital distribution of multiple files over the internet. It should not be confused with compression/decompression format as tar is merely a tool to collate multiple files together. Combined with other compression tools and formats such as bzip2 or gzip, a tar file can then be compressed or decompressed as needed.
