Unwrap: winmail.dat Opener
Open TNEF Email Attachments
Only for Mac
USD 0.99
Mac
Open winmail.dat instantly. Read the message, browse every attachment, and save what you need — all processed on your Mac, nothing uploaded.
Ever received an email attachment named "winmail.dat" that nothing on your Mac could open? Unwrap decodes it instantly, right on your Mac, with nothing ever uploaded anywhere.
Outlook and Exchange sometimes send Rich Text formatted email wrapped in a format called TNEF, which shows up as an unreadable file named winmail.dat instead of the message and files you were actually sent. Unwrap reads that format natively and shows you exactly what was inside: the original message text and every attached file.
WHAT UNWRAP DOES
• Open winmail.dat (or any TNEF-encoded) file with a double-click, ⌘O, or a simple drag and drop
• Recovers the original message text, including rich formatting where present
• Browses every attachment in a clean grid with file icons and sizes
• Saves a single attachment, or all of them at once, to any folder you choose
• Keeps a Recent Files list so files you've opened before are one click away
• Optionally auto-saves every attachment straight to your Downloads folder the moment a file opens
BUILT FOR PRIVACY
Unwrap does its work entirely on your Mac. Nothing about your email, its contents, or its attachments is ever sent anywhere. There's no account to create, no server round-trip, and no network connection involved in opening a file.
DESIGNED FOR macOS
Unwrap is a native SwiftUI app with a clean, modern interface, full support for Light and Dark Mode, and standard macOS behavior throughout — including window restoration, keyboard shortcuts, and Quick Look–style file previews. It's a lightweight, single-purpose utility: no subscriptions, no clutter, no background processes running when you're not using it.
WHO IT'S FOR
If you've ever been sent a winmail.dat file by a colleague, client, or recruiter using Outlook or Exchange, and had no way to open it, Unwrap solves that in one click.
