Expecting a document and got a mysterious "winmail.dat" instead? That file is TNEF — a Microsoft Outlook format that Mail on iPhone, iPad, and Mac can't open. Winmail Viewer opens it in a tap and gives you everything inside. WHAT'S HIDDEN IN WINMAIL.DAT • Attachments — every file the sender attached: PDFs, images, documents, spreadsheets. Preview them with Quick Look, then save or share. • The message — subject, sender, recipients, and the full body, whether it was written in HTML, rich text, or plain text. • Calendar invitations — see the time, location, and recurrence, then add the event to your calendar. • Contacts — save the enclosed contact card straight to your address book. • Tasks — send an enclosed to-do to Reminders. HOW IT WORKS • On iPhone and iPad: open a winmail.dat from Mail, Files, or any app — tap Share and choose Winmail Viewer. • On Mac: double-click any winmail.dat, or drag it onto the app. Nothing to configure. It just opens. PRIVATE BY DESIGN Your mail is nobody's business. Winmail Viewer does everything on your device and makes no network connections of its own — nothing is uploaded, ever. Remote images and tracking pixels in message bodies are blocked before they can load. BUILT FOR APPLE PLATFORMS A fast, native app for iPhone, iPad, and Mac. Full support for Dark Mode, Quick Look, Split View, and Handoff between your devices. Handles unicode and emoji filenames in any language, decodes compressed rich-text bodies, and expands recurring meeting invitations correctly. One purchase covers iPhone, iPad, and Mac. Stop being locked out of your own attachments. Get Winmail Viewer - TNEF Opener.
