FYZ Archiver

Built for speed and privacy

A compact native engine with modern codecs, strong encryption, and no cloud dependency.

Adaptive engine

Smart mode analyses each file and routes it to the best codec - LZMA2, Zstandard, Brotli, PPMd or lossless JPEG-XL - automatically.

AES-256 encryption

Authenticated AES-256-GCM encryption with Argon2 key derivation. Optionally encrypt file names too.

Deduplication

Content-defined chunking removes duplicate data within and across files to shrink archives further.

Dictionary & long-range

Ultra unlocks dictionary-trained compression and a long-range window for better ratios on large or similar data.

Every common format
