A private desk tool

Read awkward mail files, privately.

Open winmail.dat / TNEF and EML messages in this browser. Read the message, view safe inline images, preview PDFs, and download attachments without an upload.

Quick answer

A reader for winmail.dat and EML that stays on your device

Mail File Viewer shows who sent the email, when, and what it says. Pictures inside the message are shown from the file itself, images from the internet stay blocked until you allow them, and you can download attachments one by one or as a ZIP.

EML and winmail.dat are different

EML is a complete email message

Open an EML here to read who it is from and to, its subject, the message, the pictures in it, and its attachments.

winmail.dat is an Outlook TNEF package

Open it when another mail app hides the original message or attachments inside a winmail.dat wrapper.

Open the winmail.dat guide

MSG, EMLX, and MHT files are not supported.
