How PZIP Compresses Word (DOCX)

PZIP understands the DOCX container structure and recompresses internal components with stronger codecs. The XML redundancy in styles, headers, footers, and content markup is exploited far more effectively than ZIP's per-file deflate.

Codec: Container recompression + stream separation

Lossless

Byte-exact round-trip verified on every file

Never-Worse

Falls back to LZMA if it can't beat it

Automatic

Type detection + codec selection is automatic
