Implemented. The --convert subcommand reads a source archive (auto‑detected or specified with --from) and writes it in a target format (--to). Metadata (BLAKE3/CRC32 hashes, timestamps, permissions) is automatically generated and embedded in the output archive (unless --no-internal-meta is used).

Example:

reptar --convert --from=ustar --to=pax -f legacy.tar -v

The conversion logic is in runConvert (cmd/reptar/main.go) and works with all supported archive formats.
