The LZ file format stores data in the LZ format. Converting to TAR produces a archive file that concatenates files into a single stream without compression, commonly paired with gzip or bzip2 for compressed tarballs on Unix systems. This packages the document into a compressed archive for smaller transfer size. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. This makes TAR the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
