How to open a winmail.dat file — 3 simple steps

winmail.dat attachment you received by email.
- We decode it for you: Our TNEF decoder parses the file and lists the original attachments inside.
- Download the original files: Click each extracted file to download it in its original format (.pdf, .docx, .jpg, etc.).

Why winmail.dat files appear — and how we fix them
Microsoft Outlook sometimes encodes rich text emails and their attachments using TNEF (Transport Neutral Encapsulation Format). When Outlook sends this format to non-Outlook email clients (like Gmail, Apple Mail, or webmail), attachments can arrive wrapped inside a winmail.dat file that these clients can’t open. Winmail-Dat.com decodes TNEF and restores your original files so you can access your content immediately.
- Common scenarios: Shared PDFs that become
winmail.dat, images that won’t preview, or calendars and attachments missing from the message.
- Result: Our TNEF decoder extracts the hidden attachments and presents them exactly as the sender intended.
