EML File Viewer
Open a saved .eml email without Outlook or a mail app: read the formatted message, check who sent it and save its attachments.
Remote images are blocked until you allow them, so the sender cannot see that you opened the email.
Opened in your browser. The file is never uploaded to a server.
How to use the EML Viewer
Drop the .eml file
Drag an email saved from Outlook, Thunderbird, Apple Mail, Gmail or a mail archive onto the viewer.
Read the message
See the subject, sender, recipients and date, and the message with its original formatting and embedded images.
Open attachments
Download any attachment, view the raw headers, or print the email or save it as PDF.
About the EML Viewer
An .eml file is a single email message saved in the standard internet mail format (RFC 5322 with MIME). Mail programs create them when you drag a message to the desktop or save it, Gmail offers “Download message”, and e-discovery tools and mail backups export thousands of them. Without a desktop mail client, though, Windows opens an .eml file as unreadable text.
This EML viewer decodes the message on your device: headers, plain text and HTML parts, inline images and attachments. Remote images in the email are blocked until you allow them, so opening an old message does not tell the sender that you read it. Nothing is uploaded, which makes it suitable for invoices, legal correspondence and other sensitive mail.
Frequently asked questions
How do I open an EML file without Outlook?
Drop it onto this page. The EML viewer shows the formatted message and its attachments in your browser, with no mail client or account needed.
Is it safe to open suspicious emails here?
Safer than in a mail client: scripts are removed, the message is shown in a sandbox and remote images and trackers are blocked until you allow them. Still, do not open attachments you do not trust.
Are my emails uploaded?
No. The .eml file is parsed in your browser and never sent to our server.
Can I save the email as PDF?
Yes. Click Print / PDF and choose “Save as PDF” in the print dialog.
What is the difference between EML and MSG?
EML is the open, text-based standard used by most mail programs. MSG is Microsoft Outlook’s own binary format. They contain the same kind of data but need different readers.
