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
Check the output before using it
Extraction uses a staging area and checks paths. Results explain skipped entries; review them before assuming every file was extracted.
Protected archives
Know when an archive needs a password
Password-protected archives are clearly labelled. Encrypted filenames need a password before they can be listed; limited visibility is explained.
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.
Automation
Use Terminal or your AI tools
A native command-line tool and local MCP server ship inside the app. Inspect with structured results, and deliberately enable MCP write tools for creation and extraction.

Questions, answered
Is CozyZip really free?
Personal, non-business use has a free lifetime licence with a verified email. Commercial use is US$5 once per person. Both cover up to three Macs and include future CozyZip updates. See pricing for current availability.
Are any features restricted to commercial licences?
No. Both licences include the same archive, Terminal and MCP features. The difference is permitted use: work for a business or organisation requires a commercial licence. Each person needs their own licence.
Do I need a subscription or have to accept news emails?
No subscription is required. Essential verification and licence emails are part of licensing. Blog posts and new-app announcements are a separate, optional choice, and unsubscribing from news does not cancel your licence.
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?
Archive processing stays on your Mac. The app uses online services for licence activation, checks and updates. The local MCP server runs through your chosen AI client, whose own data policies also apply.
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.
