About EML
Email has kept the same shape since RFC 822 in 1982: header lines like From, To, Subject and Date, a blank line, then the message. MIME added attachments, pictures, other alphabets and HTML in 1992. An .eml file is one email exactly as it was sent.
Mail apps save an email as EML when you drag it out or choose Save as, and Gmail's Download message writes one too. They're how emails are kept as evidence, archived or forwarded whole, and an HTML email in one can still carry trackers that load when it opens.
Filepeek shows the email as mail apps do: who sent it to whom and when, then what it says, with no script running and no picture from the web loaded. Pictures sent inside the email show, and each attachment opens in its own viewer, attached emails too. Tree and Text show its parts and source.

Questions
How do I open an EML file without Outlook?
Drop it on this page or choose Peek an EML. The email opens with its sender, date and attachments, with nothing to install.
Can I open the attachments?
Yes. Each one opens in its own viewer when you click it, and an attached email opens as an email.
Why are some pictures missing?
They load from the web, which would tell the sender you opened the email. Pictures sent inside the email show.
Can I see the headers?
Yes. Choose Tree for every header line and part, or Text for the email's source.
Is my file uploaded?
No. The file opens inside your browser and never leaves your device.
