A free viewer for .msg, .eml, .mbox (including Google Takeout exports), and winmail.dat. Drop a file above and it opens right away. The parsing happens on your device, so message content is never sent anywhere.
One drop zone, four formats
You don't have to know which format you have. Drop a file on the zone above and it checks the file's actual bytes (not its extension or icon) to tell an Outlook message container apart from a TNEF blob, an mbox archive, or plain MIME, then opens the matching viewer automatically. If you already know what you're dealing with, jump straight to it from the menu; dropping the "wrong" type there still works, it just tells you what it actually found.
How your files are handled
The message body renders inside a locked-down frame with scripts and same-origin access both switched off, so even a hostile message can't execute anything. Pictures and other content referenced by a remote URL are blocked by default in every message (that's how a sender's tracking pixel would otherwise learn exactly when and where you opened it), and loading them is a per-message choice you make, not the default. Nothing is written to storage, so closing the tab clears the session.
How to Open an Email File Without Outlook
Whether you have a .msg, .eml, .mbox, or winmail.dat file, the steps are the same, and Outlook is never one of them.
1
Open this page: nothing to install
Everything runs in the browser tab you already have open. There's no download, no account, and no Outlook, Thunderbird, or Apple Mail to set up first. It works the same on Windows, Mac, Chromebook, or phone.
2
Drop your email file on the box at the top
Drag in a .msg, .eml, .mbox, or winmail.dat file, or click to pick one. You don't need to know which format you have: it reads the file's actual bytes to identify it, then opens the right viewer automatically.
3
Read the message
The sender, recipients, date, full body, and every header appear right away, parsed entirely on your device, never uploaded. Remote images stay blocked until you choose to load them, so a sender's tracking pixel can't fire.
4
Save attachments or keep a copy as PDF
Download any attachment straight from the message, or use Print / Save as PDF to keep the email itself as a file you can archive or forward.
Open MSG Files
Why can't I open a .msg file?
+
A .msg file is Outlook's own saved-message format, so it only opens natively inside Outlook for Windows. Mac Mail, Gmail, and most other apps don't understand it, which is why double-clicking one usually does nothing or offers to download an app you don't want. Drop it above to read it instantly instead.
How do I open a .msg file on a Mac?
+
Drop it on this page. It reads the sender, recipients, date, body, and every attachment directly, without installing Outlook or any other app. Older .msg files saved before Outlook defaulted to Unicode read correctly too, not just recent ones.
Can I turn a .msg file into a PDF?
+
Yes, two ways. Print / Save as PDF keeps the message looking exactly as it does on screen. Or use Download PDF for a clean report: the full sender and recipient details, the date in plain and universal time, the message text, and a list of every attachment with its size and a content fingerprint. Both happen on your device; nothing is uploaded.
How do I convert an .msg file to PDF?
+
Open the .msg here and pick either export on the message toolbar: Print / Save as PDF for an exact-looking copy, or Download PDF for a compact records-style report. Every online converter you'll find uploads your email to their server first, but this one never does.
Open EML Files
What opens .eml files?
+
Most desktop mail apps can, but that means importing it into a mail profile just to read one message. This page reads it directly: drop the file and it opens immediately, nothing installed.
Why can't I open an .eml file without Outlook?
+
Windows sometimes has no default app registered for .eml at all. You don't need one, just open it here instead.
Can I convert an .eml file to PDF?
+
Yes, open it here and choose Print / Save as PDF for an exact-looking copy, or Download PDF for a clean report with the headers, timestamps and an attachment list.
How do I convert .eml to PDF without installing anything?
+
Drop the .eml on this page and use the export buttons on the message: no app, no sign-up, and no upload. The file is read and the PDF is built entirely in your browser.
Open MBOX / Google Takeout Files
How do I open a Google Takeout mbox file?
+
Drop the .mbox file above. It's scanned in small chunks (never loaded all at once) so even a multi-gigabyte export works, and you'll see messages appear in the list while the rest keeps scanning.
How do I open an mbox file without Thunderbird?
+
Drop the .mbox file above, and it opens right here, with no Thunderbird profile and no import wizard. The archive is read in small chunks on your device, so even a multi-gigabyte Google Takeout export works.
Can I export mbox messages to PDF?
+
Yes. Open a single message and use Print / Save as PDF or Download PDF, or tick several messages in the list and choose "Export to one PDF" to combine them into a single report PDF, all without uploading anything.
Can I combine many emails into one PDF?
+
Yes, select the messages you want in the archive list and choose "Export to one PDF". They're written into a single report PDF in the order shown, each with its headers, date, body and attachment list. You can also save the selected messages back out as .eml files or pull all their attachments in one download.
Open winmail.dat Files
Got one of these? There's a full winmail.dat opener page covering Thunderbird, Gmail, Mac and phones, plus how to make the sender stop.
What is winmail.dat and why did I get it?
+
It's Outlook's "Rich Text Format" (TNEF) email packaging. When the sender's Outlook is set to compose in Outlook Rich Text and the recipient's mail app doesn't understand that format, everything (message body and attachments) gets bundled into one file named winmail.dat instead of showing normally.
How do I open a winmail.dat file on a Mac?
+
Drop it above: it unpacks the message and attachments right here, no installs. Once it's open you can save the attachments, or turn the unpacked message into a PDF with Print / Save as PDF or Download PDF, just like any other email.
How do I stop receiving winmail.dat files?
+
Ask the sender to change their Outlook compose format to HTML or Plain Text instead of "Outlook Rich Text" (in Outlook: File → Options → Mail → Compose messages → Message format), or to send messages to you specifically as Plain Text/HTML from the format menu when composing. Feel free to share this page with them.
Convert an Email to PDF (EML, MSG, MBOX)
Two ways to save an email as a PDF, both entirely on your device, so pick the one that matches what you need the PDF for.
Print / Save as PDF: the exact look
This keeps the message looking precisely as it does on screen: the formatting, inline pictures, tables and colours all intact. It's the right choice when what matters is that the PDF looks like the email looked. It goes through your browser's own print dialog, so it works the same on a Mac, a PC or an iPhone (Save to Files).
Download PDF: the clean report
Built for records: the full From, To and Cc lines, the date shown both as it was sent and in universal time, the subject and message-id, the message text, and a list of every attachment with its type, size and a content fingerprint. The layout is fixed and every page is stamped with the source file and the moment you exported it. It describes what the email contained, but we don't claim a court will accept it, only that it's complete and stable.
The difference that matters: nothing is uploaded
Nearly every "email to PDF" converter you'll find in search results asks you to upload your .eml or .msg file to their server first: your private mail, on someone else's machine. This one converts the file right in your browser tab. It never leaves your device, so it works for confidential HR, legal and personal mail where uploading simply isn't an option. It reads .msg, .eml, mbox messages and unpacked winmail.dat alike, since they all become the same kind of message once opened.
Combine a batch of mbox messages into one PDF
Opening a Google Takeout mbox archive? Tick the messages you want in the list and choose "Export to one PDF"; they're written into a single report PDF in the order you see them, each starting a fresh page with its own headers, date, body and attachment list. You can also save the selected messages back out as individual .eml files, or pull every attachment across the selection in one download. It all runs locally, so even a large selection from a multi-gigabyte archive stays private.
What does the report PDF include?
+
The Download PDF report is built for records: the full From, To and Cc lines, the message date shown both as sent and in universal time, the subject and message-id, the message text, and a list of every attachment with its type, size and a content fingerprint. It's a description of what the email contained, but we don't claim it's legally admissible, only complete and stable.
Where This Tool Draws the Line
What it won't render, on purpose
Attachment previews are limited to images and PDFs, checked against the file's actual bytes rather than its declared type or extension. Anything else (including an HTML or SVG attachment) downloads as a file and is never displayed, because an attachment is exactly where a malicious email would try to run something.
A message forwarded inside another message opens in place with a breadcrumb trail, up to five levels deep. Past that, rare as it is with long forward chains, you open the innermost file on its own.
Two kinds of PDF export ship today: Print / Save as PDF for an exact-looking single message, and Download PDF for a clean report: for one message or for a batch of selected mbox messages combined into a single file. What's deliberately left out is any claim of legal admissibility; the report describes what an email contained, nothing more.
Built for evidence & discovery work
Full raw headers in one tap (the received chain, message-id, everything) with a copy-all button
Every attachment saved individually, byte for byte, shared straight from a phone's share sheet, or pulled in one download across a whole mbox selection
Save messages as .eml (one at a time or a selected batch as a zip) to hand off or re-open elsewhere
Download PDF for a records-style report of one message or many: full headers, timestamps, and a list of every attachment with a content fingerprint
