How It Works
This tool parses .eml files (RFC 822 / MIME format) entirely in your browser using JavaScript. It extracts headers, body parts (plain text and HTML), and attachments including inline images.
The parsed email is then written into a Compound File Binary (CFB) container — the format used by Microsoft Outlook .msg files. MAPI properties are set for subject, sender, recipients, dates, message body, and attachments.
What is preserved: Subject, From, To, Cc, Bcc, Date, plain text body, HTML body, attachments (with filenames and MIME types), Message-ID, and transport headers.
Limitations: Some Outlook-specific properties (categories, flags, custom forms, voting buttons, S/MIME signatures, calendar invites) may not be fully represented. The generated MSG should open correctly in Outlook for Windows for standard email messages.
Privacy: Your email file is processed entirely in your browser using JavaScript. No data is uploaded, no external APIs are called, and no analytics events contain any email content.
