Overview

What Is MSG to HTML Conversion?

MSG is Microsoft Outlook's native format for a single email — an OLE2/CFB (Compound File Binary) container storing MAPI properties and body (plain and/or HTML). Converting MSG to HTML means parsing that binary and writing the message as an HTML document: headers (From, To, Subject, Date) plus the body. When the MSG has an HTML body, it is preserved; otherwise plain text is used in a simple HTML structure.

Our free converter processes entirely on your device. You drop one .msg file; the tool parses the OLE2 container, extracts headers and body, then produces a single .html file. All processing is private; nothing is uploaded.

Use MSG to HTML for viewing emails on any device, embedding in web pages, or archiving in a portable format. No Outlook installation is required — works on Windows, Mac, or Linux.

One MSG file yields one HTML file. For bulk conversion, use multiple MSG files or our PST to HTML converter.

MSG is Outlook's single-message format (OLE2/CFB). The tool parses the MSG and exports the message as an HTML document — with From, To, Subject, Date, and the body (HTML if present in the MSG, otherwise plain text). You get a single .html file that you can open on any device.

Q2. Why convert MSG to HTML?

HTML is ideal for viewing emails on any device, embedding in web pages, or archiving in a portable, viewable format. No email client required.

No. Conversion runs entirely on your device. Your file is read and parsed on your device. Nothing is sent to our servers.

Q4. Do I need Outlook installed?

No. The converter works on any modern platform — Windows, Mac, or Linux. No Microsoft Outlook required.

Q5. Does the HTML preserve formatting?

When the MSG contains an HTML body, the tool uses it so formatting is preserved. If only plain text exists, the output is plain text wrapped in a simple HTML structure.
