Open and view EML files
Someone sends you a .eml attachment — from a helpdesk export, a lawyer, an old backup — and double-clicking it either opens nothing or tries to import it into a mail account you don't want it in. An .eml is just a text file in RFC 5322 format, but raw MIME is unreadable to humans: base64 blocks, boundary strings, encoded headers.
This viewer parses the file in your browser and shows the message the way a mail client would: who sent it, to whom, when, the subject, the readable body, and what attachments it carries. Nothing installs and nothing uploads — the file is parsed in memory on your own machine, which also makes it a safe way to inspect a suspicious .eml without importing it into your real mailbox.
Need a permanent copy? The same engine converts what you're viewing to a clean PDF with the full header block — one click, still local.

Questions
Is it safe to open an unknown .eml here?
Parsing happens as data, not as a live email: scripts don't run, remote images don't load, attachments aren't executed. It's a safer way to inspect a suspicious message than opening it in your mail client.
Can I see the raw headers?
The labeled block shows the key headers (From, To, Cc, Date, Message-ID). Full raw-source view is on the roadmap; for most uses the parsed block is what you need.
Does it work on a phone?
Yes — any modern mobile browser. Large mbox archives are better on a laptop for memory reasons, but single .eml files open fine on a phone.
