Read an .eml email without a mail program: sender, recipients, date, the message with its pictures, and every attachment. Save it as a PDF or print it. The file stays on your device.

Your file stays on this device: it is read here, in your browser, and never uploaded.
One message, or many at once. Outlook .msg files open here too.
How it works
1
Choose the .eml file
Or several at once: you get a list of the messages and open them one by one. Outlook .msg files open here too.
2
Read the message
The headers, the text or the formatted (HTML) version, the pictures sent inside the message and the attachments. Pictures stored on the internet are not loaded, so the sender cannot tell that you opened it.
3
Save what you need
Save the message as a PDF, print it with its original formatting, or save the attachments one by one. Attached emails open here too.
EML files, explained
What an EML file is
An .eml file is one email saved in the internet’s standard message format (RFC 5322 with MIME): the headers (who sent it, to whom, when, the subject), the text, often a formatted HTML version, and the attachments, all in one plain-text file. The attachments are inside it, encoded as text, so the file is usually larger than the message looks.
Where you get one
Saved from a mail program. Thunderbird, Apple Mail, Outlook and many webmail services save or export a message as .eml (in Gmail: More → Download message).
Forwarded as an attachment. When someone forwards an email “as attachment”, it arrives as an .eml file.
Exports and archives. Backup tools, mail archiving systems, eDiscovery exports and the bulk export of our MBOX and PST viewers produce folders full of .eml files.
Evidence and records. Lawyers, accountants and HR departments are often sent the original email as .eml, because it keeps the full headers.
Why it won’t open
An .eml file opens with a double-click only when a desktop mail program is set up to handle it. On a computer without one, or on a work machine where you cannot install software, the file may open in a text editor, which shows raw headers and the attachments as long blocks of encoded text. Phones and tablets often show an .eml attachment as a file they cannot preview.
What this viewer does
Opens .eml files up to 150 MB (Apple Mail .emlx and Outlook .msg files too) in your browser, without uploading them.
Shows the sender, recipients, the sent date and, when the message traveled through mail servers, when it was received; the full original headers are one click away.
Shows the formatted (HTML) message in a locked-down frame where no script runs and nothing is fetched from the internet, so tracking pixels cannot report that you opened it. Pictures sent inside the message are shown.
Decodes international text: UTF-8, ISO-8859 and Windows character sets, quoted-printable and base64, encoded subjects and attachment names.
Opens messages signed with S/MIME, including the “smime.p7m” kind where the message is inside the signature, and names the signing certificate; the signature itself is not verified.
Saves each attachment, and opens attached emails (.eml or .msg) as messages of their own.
Saves one message as a PDF (header, text, the PNG and JPEG pictures sent inside it, and the list of attachments) or prints it with its original formatting; your browser’s print dialog can also save that as a PDF.
Converts many messages at once (a paid feature): one PDF per message in a ZIP or all of them in one PDF, plus the attachments and a spreadsheet index.
What it does not do
It does not check digital signatures: a signed message is shown with the certificate’s name, but not verified.
It cannot open encrypted messages (S/MIME or Microsoft rights protection): they need the recipient’s private key or account. The headers are shown.
It never loads pictures stored on the internet, in the viewer, the PDF or the printout; the PDF shows their description (alt text) where they were.
The saved PDF has a simplified layout. It keeps Western and Central European letters, Vietnamese, Greek and Cyrillic; Arabic, Hebrew, Chinese, Japanese, Korean and emoji appear as “?”. Pictures in GIF or WebP format are named, not drawn. Print, then “Save as PDF”, keeps everything sent inside the message.
It does not change or repair the file.
Frequently asked questions
How do I open an EML file without Outlook?+
Choose it here: the message opens in your browser with its attachments. Thunderbird and Apple Mail also open .eml files, if you have them installed.
How do I open an EML file on an iPhone or Android phone?+
Save the .eml to Files (iPhone and iPad) or Downloads (Android), then open this page in Safari or Chrome and choose it. The message and its attachments appear in the browser.
Is my email uploaded?+
No. The .eml file is read by code running in your browser and never leaves your device. No code on the page sends the file or its name anywhere, not even to our own domain; the usage events described in the privacy policy never include the file, its name or its contents.
How do I convert an EML file to PDF?+
Open it here and press “Save as PDF”. The PDF has the subject, sender, recipients, dates, the text with the PNG and JPEG pictures sent inside the message, and the list of attachments. To keep the original formatting, every alphabet and every picture type sent inside the message, press “Print” and choose “Save as PDF” as the printer (pictures stored on the internet never load). One message at a time is free.
Can I convert many EML files to PDF at once?+
Yes. Choose all the files together (up to 10,000), then “Convert all”: you get one PDF per message in a ZIP, or all of them in one PDF (up to 1,000 messages), and if you want, a ZIP of the attachments and a CSV index. This is a paid feature (a 30-day pass or a yearly plan); during the launch it is free too.
Why are some pictures missing?+
Many emails load their pictures from the sender’s server when you open them, which tells the sender that you read the message. This viewer never contacts those servers, so those pictures stay blank, in the PDF and the printout too; “Show where they are” outlines their places without loading anything. Pictures sent inside the message are shown.
How do I save the attachments from an EML file?+
Open the file here and press “Save” next to each attachment. An attached email can also be opened here, with its own attachments.
The message says winmail.dat is attached. What is that?+
Outlook packed the attachments into a winmail.dat file. Press “Open in the winmail.dat opener” next to it and the winmail.dat opener unpacks them.
Can I open the email in Outlook afterwards?+
Yes: an .eml file can be dragged into an Outlook folder or opened with Outlook for Windows. This viewer does not change your file.
