zipseal

Seal it.
Send it.

Zipseal makes a password-protected zip of your files in one step. It makes a strong password and writes the note for the recipient. It also opens the archives that other people send to you.

Download on the Mac App StoreFor macOS 15 or later.

The Zipseal window after Secure share: Brand refresh.zip is ready, with a note for the recipient, a generated password, and a Copy Password button.

Secure share, right from Finder

For contracts, invoices, photos, and client files. On a Mac, the recipient needs no special app.

  1. Select the files

    Right-click in Finder, then choose Quick Actions > Secure Share with Zipseal. Or drop the files on the window.

  2. Send the zip

    Zipseal makes a zip with AES-256 encryption next to your files. Attach it to an email, or use AirDrop or Messages.

  3. Send the password another way

    Copy the password and send it in a text message, or say it on a call. Never in the same email as the zip.

A Finder window with four files selected. The context menu shows Quick Actions, with Compress with Zipseal and Secure Share with Zipseal.

Look inside before you extract

Browse an archive like a folder. Preview a file with Quick Look, drag one file out, or extract only what you select.

The Zipseal Browse window shows the folders and files inside Brand refresh (from client).zip. Quick Look shows Moodboard.jpg from the archive, before extract.

The details are done for you

Clean archives
Zipseal never adds the hidden Mac files (__MACOSX, .DS_Store) that confuse people on Windows.
Safe extract
Zipseal stops paths that try to write outside the folder, and it warns you about archives that expand to a very large size.
Large files
Split a large zip into parts, for example 25 MB for email. Open archives in parts that other people send.

No account. No subscription.

Pay once
Buy it one time on the Mac App Store.
Data Not Collected
No analytics and no tracking. Zipseal never stores or logs your passwords.
No network access
The app cannot send your files anywhere. Your files stay on your Mac.
