FAQ
What is a winmail.dat file?
Microsoft Outlook sometimes wraps an email's attachments in a format called TNEF. Gmail, Apple Mail, Yahoo and most phones cannot read it, so they show one file named winmail.dat instead.
Why did I get it instead of the PDF or Word file?
The sender's Outlook sent the message as Rich Text. Your real attachments are inside winmail.dat, and this page takes them out.
The page says there are no files inside. Why?
Some winmail.dat files carry only the email's formatting, with no attachment. In that case nothing is missing; the message text you already see is all there is.
Is my email uploaded?
No. The file is opened inside your browser, so the attachments never leave your device.
How can the sender stop this happening?
Ask them to send the email as HTML or Plain Text instead of Rich Text in Outlook's message format settings.
Is it free?
Yes. There are no ads, no watermark and no daily limit.
