Compress. Encrypt. Keep it private.
A native Windows file archiver with an adaptive compression engine, AES-256 encryption and cross-archive deduplication. Everything runs on your machine.
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
Create FYZ, ZIP, 7z, TAR and TAR.GZ. Extract those plus RAR - all from one clean interface.
Native & local
A compact native engine that starts instantly and uses all your CPU cores. Your files never leave your device.
