Drag, drop, compress, extract. mac7z wraps the battle-tested 7-Zip engine in a clean, native-feeling UI — built entirely with Flutter & Claude AI.
Features
Drop any archive directly into the window to instantly preview and extract its contents.
Create .7z and .zip archives with adjustable compression level, from Store to Ultra.
Create and extract multi-volume archives (.7z.001, .zip.002…) with automatic detection.
Password-protected archives with AES-256 and header encryption for .7z.
Browse archive contents before extracting — names, sizes, modification dates, search.
Fully localized UI — French, English, Spanish, German, Japanese, Arabic and more.
