What Is an EML Viewer?
An EML viewer is a free online tool that opens and displays .eml email files directly in your browser without needing an email client. EML is a standard email format used by Outlook, Thunderbird, and other email applications. This tool lets you view headers, body content, and attachments from any .eml file.
How the EML Viewer Works
Upload an .eml file and view its contents instantly:
- Drag and drop or browse to select an .eml file.
- View parsed email headers (From, To, Subject, Date).
- Read the email body in both text and HTML formats.
- See raw source code and header details.
- Download the original .eml file or clear and start over.
Key Features
- Multiple views: Switch between raw, headers, parsed, and body views.
- HTML rendering: View HTML emails as they would appear in an email client.
- Attachment detection: Identifies attachments within the .eml file.
- Privacy-first: Files are processed locally in your browser — never uploaded to a server.
