About EML File Viewer
A .eml file — exported from Outlook, Apple Mail, Thunderbird, or downloaded from Gmail — is a plain-text MIME-formatted email that most systems can't open directly without launching a full email client just to read one message.
This tool parses a .eml file's headers and body directly in your browser, showing the From, To, Subject, and Date fields clearly labeled, along with the readable plain-text body content — HTML formatting and tags in the message are stripped for a clean read.
This handles both simple plain-text emails and multipart messages (the common case where an email includes both an HTML and plain-text version) — for multipart messages, the plain-text portion is extracted directly rather than showing raw MIME boundary markers.
How it works
- Upload a .eml file. Choose an exported email file from your device.
- Review the headers. See From, To, Subject, and Date clearly labeled.
- Read the body. The message content is shown as clean, readable text.
