The ar file extension is associated with ar, a Unix utility that maintains groups of files as a single archive. The archive contains individual member files that can be listed, extracted, added, replaced, or removed.

GNU ar, part of GNU Binutils, creates, modifies, and extracts files from ar archives. The utility is available on Linux and other Unix-like systems, although compatible implementations are also provided with some Unix systems.

How to open ar file?

On Linux or Unix, use the ar command to inspect or extract the archive. For example, ar t lists its contents and ar x extracts the member files. GNU ar and compatible Unix ar implementations can open this format.

How to convert ar file?

An ar archive is not normally converted to another format. Extract its member files with ar, then create a new archive with the appropriate archiving program if a different format is required.
