The problem
Archives can hide more than you expect
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, and takes the same care with the archives you create.
Features
What CozyZip does
Safety Check
A plain-language read on what is risky
Scripts, executables and misleading extensions are flagged, with a short explanation of why each one deserves a second look.
Guardrails
Unsafe entries are blocked, not just flagged
Path traversal entries and symlinks are never extracted, so an archive cannot write outside the folder you picked.
Staged extraction
All or nothing, never half an archive
Files are extracted to a staging area, checked, then moved into place. A failed or cancelled job leaves no mess behind.
Protected archives
See protected archives before unlocking them
Password-protected archives are clearly labelled, and you can review the file list before entering anything.
Create
Make archives as easily as you open them
Drop files and folders in, choose ZIP, 7z or TAR.GZ, and create. An existing archive is only replaced once the new one has been written successfully.
Encrypt
Lock an archive with a password
Protect ZIP and 7z archives with AES-256 encryption. With 7z you can encrypt the file names too, so the contents list stays private.
Clean output
No Mac clutter for the person receiving it
__MACOSX folders, .DS_Store and other Mac-only metadata are left out of the archives you create, and skipped in the ones you extract.
Finder
Right where you already work
Drag and drop, an Extract with CozyZip item in Finder's right-click menu, and a recents list.

Questions, answered
Is CozyZip really free?
Yes. There is no trial, no paid tier and no account.
Can CozyZip create archives too?
Yes. It creates ZIP, 7z and TAR.GZ archives, with optional AES-256 password protection for ZIP and 7z. TAR.GZ archives cannot be password protected.
Can anyone open an encrypted ZIP I make?
They need an app that supports AES-256 encrypted ZIPs, such as CozyZip or 7-Zip. The archive tools built into macOS and Windows may not open them.
Was this app called CozyUnzip?
Yes. It was renamed CozyZip when it gained the ability to create archives as well as extract them.
Does CozyZip upload my files?
No. CozyZip is sandboxed and has no network access. Everything happens on your Mac.
Which Macs are supported?
Apple Silicon Macs running macOS 26 or later.
Why inspect an archive before extracting it?
Archives can contain scripts, executables or files aimed at locations outside your chosen folder. Looking first lets you decide what is worth extracting.
Is CozyZip an antivirus?
No. It 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.
