Open an email file online, free
You have an MSG, EML or EMLX file and nothing on the machine that opens it. Upload it here, up to 10 MB, and the message renders with its headers and attachments intact.
Drop the file
From your computer or your phone
We render it
On our server, so nothing installs on yours
You read it
And your copy is deleted when you close it
What you get when the message opens
Upload a message and it renders the way the recipient saw it: sender and recipients, the date, the subject, the body with its formatting, and the attachments listed underneath it.
There is nothing to install and no account to make. One message at a time, up to 10 MB, straight from the browser.
When an email is the record of something — an approval, a price, a chain forwarded into a dispute — the evidence is in the headers. Date, Message-ID and the Received lines are shown here, which is more than a mail client does without being asked.
MSG without Outlook
Outlook writes its own binary format, and nothing else on your machine reads it. Upload the file and the message opens anyway.
The attachments, separately
Whatever was sent inside the message is listed on its own, so you can open the invoice without hunting through the email that carried it.
The full header trail
From, To, Cc, Date, Message-ID and the Received lines — the part you need when the question is who sent what, and when.
Your file does not stay
The message is deleted once you have viewed it. Nothing is kept on our side.
Search a long thread
Search the body and the headers, which is how you find the one sentence buried forty replies down a forwarded chain.
Print it as it looks
The printed page keeps the sender block and the layout of the message instead of dumping the text.
An MSG file is Outlook's own binary format. If someone sent you one and you are on a Mac, on Linux, or on a Windows machine without Outlook installed, double-clicking it gets you nothing — the system has no idea what is inside. Upload it here, up to 10 MB, and the message opens: sender, recipients, date, subject, the body with its formatting, and the attachments listed underneath.
EML is the opposite kind of file and the opposite problem. It is plain MIME text — the format Thunderbird, Windows Mail, Apple Mail exports and Gmail downloads all produce — so it will open in a text editor, and what you get is raw source with the body encoded as base64. Readable is not the same as legible. Apple Mail's EMLX is that same MIME message with a byte count in front of it and a metadata property list behind it. All three render here as messages rather than as source.
The headers are the part people come back for. When an email is the record of a decision — an approval, a price, a chain forwarded into a dispute — Date, Message-ID and the Received lines are what carry it, and mail clients hide them by default. They are shown with the message here. The file is deleted after viewing, and the same viewer covers 70+ formats, so an attachment that turns out to be a DWG or a PSD has somewhere to go too.
What is actually inside an email file
The same message, two containers. The container is the reason one of them will not open.
EML — plain MIME text
The open format almost everything except Outlook writes: Thunderbird, Windows Mail, Apple Mail exports, Gmail downloads. Headers, body and attachments sit in one text file with the body base64-encoded, which is why opening it in a text editor shows you the file without showing you the message. Apple Mail's EMLX is the same thing with a byte count in front and a metadata property list behind.
MSG — Outlook's binary container
A compound file rather than text. Message, recipient list, attachments and Outlook's own properties are packed into one structure that only Outlook reads, which is why an MSG someone forwards you sits on the desktop doing nothing.
Frequently Asked Questions
Didn't find your answer in the FAQ? Contact our sales team
Is it safe to view my Email document online?
The upload travels over HTTPS, and your Email file is reachable only through a random identifier your browser holds and nothing links to. It is deleted once you have viewed it, which is the part that matters most.
Does Doconut store uploaded Email files?
It's important to note that we do not store uploaded Email files after processing. It gets deleted as soon as it is viewed. You are requested to avoid uploading invalid format, corrupt or infected documents here.
Are there any limits to using Doconut.app to view Email files?
One Email file at a time, up to 10MB. That ceiling is set per format, so another viewer here may take more or less than this page does.
NEED THIS INSIDE YOUR OWN APP
The rendering behind this page ships as an SDK: 75 extensions across 18 families, MSG and EML among them, running on your servers so the message never leaves them.
