EML TO MSG
Outlook can already read EML. Here is the safe path to a real .msg file, without a converter that corrupts metadata.

This format needs a container format that cannot be written safely from JavaScript. Convert to EML instead and import it with the desktop workflow described below.

The conversion runs in your browser with JavaScript. Your .msg file is read from disk and never uploaded to our servers.
There is no database and no upload folder behind this page, so there is nothing to delete later and nothing that can leak.
No account, no email address, no software install. Open the page, drop a file, take the result and close the tab.
Message bodies, headers and attachments stay yours. Nothing is read, logged, shared or repurposed by us at any point.
// Postmarked in three steps
One file or a batch of them — everything is read directly in your browser, nothing is sent to a server.
Choose from EML, PDF, TXT and more. Each conversion keeps the header, body and attachments intact.
Your converted file is ready in seconds — no email, no account, no waiting in a queue.
// 01
MSG is the file format Microsoft Outlook uses to save a single email, contact, or calendar item. It stores the header (sender, recipient, subject, timestamp), the message body, and any original attachments in one file — which is why it can typically only be opened natively in Outlook.
// 02
MSG is a Compound File Binary container full of MAPI property streams — the same structure Windows uses for OLE documents. Reading it is well understood; writing one that Outlook accepts means reproducing property tags, named-property maps and stream naming exactly, and a mistake produces a file that opens empty or crashes the preview pane. Since Outlook opens EML files natively and re-saves them as MSG with one keystroke, the honest answer is to let Outlook do the writing.

Open the EML in Outlook, then File → Save As and choose Outlook Message Format (*.msg). Outlook writes a fully valid MSG, metadata included.
A hand-written MSG that Outlook opens empty is worse than no file at all. We only ship conversions we would rely on ourselves.
Then you don't need MSG — keep the EML. Every other mail client reads it, and our MSG Viewer reads the format going the other way.
