What this viewer does
- Sender, recipient, subject, and date shown clearly
- Renders HTML-formatted emails safely in a sandboxed frame
- Falls back to plain text when no HTML body is present
- Lists and downloads attachments individually
- Works with emails exported from Gmail, Outlook, Apple Mail, and others
How it's rendered
Custom MIME parser. Parses the email's MIME headers and multipart body (RFC 822/2045) directly, entirely in-browser.
Nothing about this file is ever sent to a server — open your browser's DevTools Network tab while using this viewer and you'll see no request carrying your file's contents.
100% Private
Files never leave your device. There is no server that ever receives your file's contents.
No Uploads
Every format is decoded and rendered locally via WebAssembly or JavaScript. Open your browser's Network tab and confirm nothing is sent.
No Storage
Nothing is written to a server or database. Memory clears the moment you close or reload the tab.
GDPR-friendly by design
There's no file data collection to comply with in the first place — no account, no tracking of file contents, no analytics on what you view.
EML viewer — FAQ
What is an EML file?
EML is the standard file format for a single saved email message, readable by most email clients and produced when you "save as" or export an email.
Is the HTML email content safe to view?
Yes — the email body renders inside a sandboxed frame, so any embedded scripts or styles in the email can't affect the rest of the site.
Can I download attachments?
Yes, each attachment listed below the email body can be downloaded individually.
Is my email uploaded anywhere?
No, it's parsed and rendered entirely in your browser.
Does it work for emails with images?
Yes, inline images embedded in the HTML body display normally.
