How to convert a .msg file to HTML
Outlook stores emails in the proprietary .msg format, which most apps and browsers cannot open. Converting to HTML gives you a clean, self-contained page: the rich text, layout, and inline images are baked into a single file that opens in any browser — perfect for archiving, embedding in a page, or sharing a message that anyone can read without Outlook.
Convert .msg to HTML in 3 steps
- Open MSGViewGo to msgview.app in any modern browser on Windows, Mac, Linux, ChromeOS, iOS, or Android. There is nothing to install and no sign-up.
- Drop your .msg fileDrag the .msg onto the page, or click to choose it. The email is parsed inside your browser tab — sender, recipients, date, body, and attachments — and never uploaded.
- Click HTMLIn the Convert panel, click HTML. Your browser saves a self-contained .html file with the formatting preserved and inline images embedded, ready to open anywhere.
Why convert .msg to HTML?
HTML is the universal format for a formatted email. Unlike a raw .msg, an HTML file opens with a double-click in every browser, so you never need Outlook or a Microsoft 365 subscription to read it again. Because MSGView embeds the inline images directly into the file, the result stays intact when you move it between computers, drop it into an archive, or store it long-term — there are no missing-image placeholders. It is also the easiest format to paste into a website, a wiki, or a knowledge base when you need to embed the original message. If you would rather have a fixed, printable page, you can convert the same .msg to PDF instead; and if you need to move the email into another mail client, EML is the portable choice.
Private by design
MSGView never sends your email anywhere. When you drop a .msg on the page, it is read into your browser's memory and parsed on your own device — the conversion to HTML happens entirely client-side. Nothing is uploaded, there are no accounts, no watermarks, and no server-side processing, and you can confirm it yourself by watching your browser's Network panel while you convert. The generated HTML is self-contained, so opening it later does not fetch anything from remote servers either — remote tracking pixels stay silent. MSGView handles CJK, Cyrillic, and other encodings, decodes winmail.dat / TNEF, and opens nested or embedded emails, all inside the tab, for files up to 100 MB.
FAQ
Does the HTML keep the original formatting and images?
Yes. MSGView preserves the email's rich formatting and embeds inline images directly into the HTML file, so it looks like the original and still displays correctly even when you are offline.
Are tracking pixels and remote content removed?
The file MSGView produces is self-contained, with inline images embedded rather than linked. Because your browser does not fetch anything from external servers when you open it, remote tracking pixels do not phone home.
Is it private to convert a .msg to HTML this way?
Yes. Your file is read into the browser's memory and parsed on your device. Nothing is uploaded to any server — you can verify this in your browser's Network panel while the conversion runs.
