Introducing CozyZip
Our first app is a free archive utility for the Mac that shows you what is inside an archive before anything is extracted.
CozyZip 1.0 is out. It is a free archive utility for macOS that opens and creates archives, and it is built around one idea: you should see what an archive contains before any of it lands on your disk.
Why another archive app
A ZIP can carry shell scripts, apps dressed up as documents, and paths that try to write outside the folder you chose. Most people double-click without looking. CozyZip shows you first.
What it does
- Preview before extracting. Browse the full file tree with names, types and sizes. Nothing touches your disk until you say so.
- Safety Check. Scripts, executables and misleading extensions are flagged, with a short explanation of why each one deserves a second look.
- Guardrails. Path traversal entries and symlinks are never extracted, so an archive cannot write outside the folder you picked.
- Staged extraction. Files are extracted to a staging area, checked, then moved into place. A failed or cancelled job leaves no mess behind.
- Create and encrypt. Make ZIP, 7z and TAR.GZ archives, with optional AES-256 password protection for ZIP and 7z.
It opens more than 20 formats, including ZIP, 7z, RAR, TAR, Zstandard and ISO.
What it does not do
CozyZip is not an antivirus and does not scan for malware. It shows you what an archive contains and blocks entries that are unsafe to extract, so you can make an informed choice. It is sandboxed, has no network access, and never uploads your files.
Get it
CozyZip is free, with no trial, no paid tier and no account. It needs an Apple Silicon Mac running macOS 26 or later.
