How do I open an .eml file without Outlook?

Drop the .eml file on this page. The message, its headers and its attachments are shown right in the browser; no mail program or account is needed.

Is my e-mail uploaded?

No. The file is read by JavaScript in your browser and nothing is sent to a server. Remote images in the message are not loaded either, so the sender cannot see that you opened it.

Private · the e-mail never leaves your browser

What it shows

Sender, recipients, date and subject — including encoded Japanese, Korean, Chinese and accented names (RFC 2047).
The message — the formatted HTML version and the plain-text version, with embedded (inline) pictures put back in place.
Attachments — name, type and size, each with a download button. File names in any language are decoded (RFC 2231).
Forwarded e-mails — a message attached to a message can be opened in place or saved as its own .eml file.
All headers — Received, Message-ID, Reply-To and the rest, for checking where a mail came from.

Safe by design

E-mail HTML is shown inside a sandboxed frame that cannot run scripts, submit forms or open pages. Remote images are blocked for privacy: tracking pixels and pictures hosted on the sender's server are never requested, so opening a message here does not tell anyone you read it. Images that are included inside the .eml file itself are still displayed.

Where .eml files come from

Gmail: open a message → ⋮ → Download message.
Thunderbird, Apple Mail, Windows Mail: drag a message to the desktop or use Save as.
Outlook: forwarded "as attachment" messages from other mail apps often arrive as .eml.

Questions

Can it open Outlook .msg files?

No. .msg is Outlook's own binary format, not MIME text. Open it in Outlook, or ask the sender to forward the mail normally.

Why are some pictures missing?

Pictures loaded from the internet are blocked on purpose. Pictures embedded in the e-mail are shown. If you need the remote pictures, open the mail in a mail program you trust.

Why can't I click the links?

The message frame is fully sandboxed so that nothing in the e-mail can act on its own. Hover a link to see its address, and copy it if you trust it.

The text is garbled. What can I do?

The viewer uses the character set declared in the e-mail (UTF-8, ISO-2022-JP, Shift_JIS, EUC-KR, GB2312, Big5, Windows-125x and others). If a mail declares the wrong one, try the other body view (HTML or plain text), which is often encoded differently.

What about winmail.dat?

winmail.dat (TNEF) attachments from Outlook are listed and can be downloaded, but their contents are not unpacked here.
