EML Viewer Online — Free Email Message Reader | Online Gallery

Open EML emails with full headers and HTML body offline. Parse and display .eml and .emlx email files with full headers, HTML/text body, and attachment list.

What is EML Email Viewer and what does it do?

The EML Email Message Viewer parses raw .eml and .emlx files and renders them as a clean readable email thread.

Shows headers, HTML body, plain-text fallback, and lists all attachments.

  • Display From, To, CC, Subject, and Date headers in a formatted header card.
  • Render HTML email body inside a sandboxed iframe or styled pre-block for plain text.
  • List all MIME attachments with filename, MIME type, and estimated size.
  • Show raw MIME source in a collapsible panel.

How does EML Email Viewer work?

Reads the .eml file as text, splits on MIME boundaries using Content-Type headers, decodes base64/quoted-printable parts, and renders each part appropriately.

100% private: all processing happens locally in your browser using client-side WebAssembly, WebCrypto, WebAudio, and HTML5 Canvas. Your files are never uploaded to any server.
