Overview

What Is MSG to EML Conversion?

MSG is Microsoft Outlook's native format for a single email — an OLE2/CFB (Compound File Binary) container storing MAPI properties, headers, body (plain/HTML), and attachment metadata. EML is the universal single-message format (RFC 5322/MIME) used by Thunderbird, Apple Mail, Gmail, and most email clients. Converting MSG to EML means reading the Outlook binary and writing a standard .eml file so you can open the message without Outlook.

Our free converter processes entirely on your device. You drop one .msg file; the tool parses the OLE2 container, extracts Subject, Sender, To, CC, body, and transport headers, then builds RFC 822-style EML. All processing is private; nothing is uploaded.

Use MSG to EML for migration from Outlook to Thunderbird or Apple Mail, for archiving emails in a portable format, or for feeding messages into systems that expect EML. No Outlook installation is required — works on Windows, Mac, or Linux.

One MSG file yields one EML file. For bulk conversion from Outlook archives, use multiple MSG files or our PST/OLM converters.
