Drop a .tar file (uncompressed) to list every entry — names, sizes, modes, owner/group, modification time, link targets, and the on-disk format. Everything runs locally; the file never leaves your browser.
.tar.gz first. Browser-side parsing.
A tar archive is a stream of 512-byte header blocks, each followed by the file's content padded to a 512-byte boundary. The original Unix V7 format had a tiny set of fields. The POSIX ustar extension added owner/group names and a magic string. GNU tar uses special type flags (L, K, x) for long names and extended attributes. PAX stores extended metadata as UTF-8 key/value records in a synthetic entry. This tool understands all four.
