EML Viewer — Open EML Files Online

Open and Read an EML File Online

Inspect a saved email message without importing it into a mail application. The viewer parses common message headers, displays a plain-text or HTML body, and lists detected Base64 MIME attachments for individual download.

Key Features

  • Common fields including subject, sender, recipients, CC, and date
  • Plain-text and sandboxed HTML message views
  • Detection and individual download of supported Base64 MIME attachments
  • Base64, quoted-printable, and common RFC 2047 header decoding

How to Use This Tool

  1. Choose or drop an .eml file in the upload area.
  2. Review the parsed message fields and switch between the available message views.
  3. Open the attachments tab to inspect or download any detected attachments.
  4. Choose another file when you want to inspect a different message.

Important to Know

  • Parsing happens in the browser, but an HTML email can still request remote images or other resources when rendered.
  • The HTML view is sandboxed without script permission; do not assume that this blocks every remote request or tracking pixel.
  • Attachment detection depends on the message's MIME structure and supported encodings.
