Free Online CPIO to TAR.XZ Converter

A file compression format that is created in a corresponding tape archiver. It’s still used in the Linux version 2.6 kernel and the 'pax' archive installer from Apple. The archive contains header information with data about access privileges, the owner and time of creation. It was created to store back-up data on tape drives and other tape devices. These days Oracle developers deliver much of their software in CPIO format.

This is a file compressor format in a Unix environment with the use of the LZMA2 compression algorithm. It’s a container for only one file, so it’s used in tandem with the tar format (tar.xz). The XZ Utils tool serves as the source program for development.
