EML File Viewer

Open and view a .eml email file directly in your browser — headers, body, and attachments — without needing a desktop email client installed to read it.

An .eml file is a saved copy of a single email, including its full headers, body content, and any attachments, but most people don’t have a default application set up to open one directly, and installing a full email client just to view one exported message is disproportionate effort. This tool renders the file’s content directly, the same way an email client would, without needing one installed.

Drag and drop or upload an .eml file, and it renders the email as it would appear in an inbox — sender, recipient, subject, date, and the formatted message body (HTML or plain text, matching however the original was composed). Expand the raw headers view to inspect technical details like the full routing path or authentication headers, useful when investigating a suspicious or spoofed email. Download any attachments bundled in the file directly.

Frequently asked questions

Is it safe to open a suspicious or unknown .eml file with this tool? 

Viewing the rendered content is generally safe since nothing is uploaded anywhere and rendering happens locally, but exercise the same caution you would with any email — avoid clicking links or downloading and opening attachments from a source you don’t trust, since the file’s actual content (a malicious link or attachment) carries the same risk regardless of which viewer displays it.

Can this show me the full email headers, including routing and authentication info? 

Yes, the raw headers view exposes the complete technical header block, including Received routing hops and authentication results (SPF, DKIM, DMARC) if present in the original file, which is useful specifically for investigating whether an email is legitimate or spoofed.

Does it handle HTML-formatted emails correctly, including embedded images? 

Yes, HTML emails render with their formatting intact, and embedded (inline) images referenced within the email’s own MIME structure display correctly rather than showing as broken image placeholders.

Can I download the attachments from within the email, not just view the message itself? 

Yes, any attachments bundled inside the .eml file are listed separately and can be downloaded individually, extracted from the email’s MIME structure just as a full email client would present them.
