SOYATOOLS / ONLINE VIEWERS
Open .msg and .eml files online
Read Outlook .msg and .eml email files in your browser, without Outlook. See the sender, recipients, date and message, and save attachments. Nothing is uploaded.
Your file is read by JavaScript on this page, on your device. It is not uploaded or sent anywhere: opening a file makes no network requests. You can even go offline after the page has loaded.
What the Windows app adds
Reading here stays free. The Windows app opens the same files and more, offline on your PC:
MSG, EML & PST Viewer – Email File Reader
- Open .pst and .ost mailboxes, .mbox/.mbx mail (such as Google Takeout) and winmail.dat.
- Load remote images for a message you trust (blocked by default).
- With Pro: save emails as PDF, save all attachments at once, and convert a whole .msg/.eml folder to PDF.
FAQ
Is my email uploaded?
No. The page reads the file with JavaScript inside your browser and sends nothing. The page sets a security policy that blocks network connections, and the message itself is shown in a sandboxed frame. You can check in your browser’s developer tools (Network tab): opening a file adds no requests.
Which files work?
.msg files saved by Outlook (Unicode and older ANSI files) and .eml files from Thunderbird, Apple Mail, Gmail downloads and other mail programs. Mailboxes (.pst, .ost, .mbox) and winmail.dat are not opened here.
What are the limits?
Scripts never run, links are turned off and images from the internet are not loaded. Inline pictures inside the email are shown. Messages that only have an RTF body are shown in a simpler form. Attachments are listed and can be downloaded, but not previewed. Be careful with program files (.exe, .js and similar). Files up to 150 MB.
