winmail.dat to PDF — read the message and save it as a document
Open a winmail.dat attachment without Outlook and save the message inside it as PDF.
About this conversion
A winmail.dat arrives when someone sends from Outlook in its own format and your mail program has no idea what to do with the result. Inside that container sits the real message — formatted text, and usually the attachments the sender meant to send. This page unpacks it and lays the message out as a document you can file, print or forward to someone who needs it in a readable shape.
Just want to look inside it?
The same tool without converting anything: open a winmail.dat archive and read it.
You are not locked into PDF
The file is parsed once and stays open, so the format is picked at the end rather than the beginning: the same winmail.dat can leave here as CSV, XLSX, ZIP, EML, MBOX, HTML, TXT or JSON. Before that you can search it by subject or address, filter by year, sender and attachment type, mark the duplicates and look through the archive overview.
Questions
- Why did I get a winmail.dat at all?
- The sender used Outlook with Rich Text formatting, which wraps the message and its attachments in one TNEF container. Every mail program other than Outlook shows that container as a single unreadable file.
- Are the attachments inside kept?
- They are listed with the message and can be saved separately as a zip. The PDF itself holds the message text and its headers.
- Do I need Outlook or a plugin?
- No. The container is unpacked in the page, on any operating system.
