Open an email without Outlook, without sending anything
A .msg, an .eml or a winmail.dat opens in this tab: header, body, attachments. The file stays on your device.
Or drop a .msg, an .eml or a winmail.dat here. Nothing is uploaded: the files stay in this tab.

One page per task, and the same workshop behind each.
Why Klarinbox
Three reasons, all of which you can check from your browser.
Your files do not leave
An email is a firm's confidential matter, an employee's file, someone's private life. The file is read by your browser, in this tab, and the page may not reach any other site (
connect-src 'self'): the browser enforces it. Remote images in a message are not loaded, as they would tell the sender it was read.Faithful and traceable
The message is displayed, not rewritten: the full header, the body as it was sent, without its remote images (loading them would alert the sender), each attachment with its name and size. An extracted attachment keeps its original name, and the archive index gives its SHA-256 fingerprint, which links it to the message it came from.
Ready for the case file
The attachments of twenty messages come out in one archive, one folder per message, with their index. An exchange can be filed without saving each attachment by hand.
What it does not do
What is worth knowing before using it.
- It is not an email client. No account, no connection to a mailbox, no sending: it opens files.
- Klarinbox does not certify that an email is authentic. It shows what the file contains and points out what looks inconsistent; it replaces neither a bailiff's report nor an expert examination.
- An encrypted message is not decrypted (S/MIME, PGP), and a signature is not verified.
- A password-protected PST is not opened, and the protection is not bypassed. A damaged mailbox is read as far as possible; deleted messages are not recovered.
- A message fits in the tab's memory. Mailboxes (.pst, .ost, mbox) are read in chunks, but a single message of several hundred megabytes may exceed what a browser grants a page.
- Klarinbox is not affiliated with Microsoft, Meta or Google. Outlook refers here to the files that software produces.
Who it is for
For lawyers who receive .msg files and WhatsApp exports to file as exhibits, for human resources holding a departed employee's mailbox, and for individuals asked for "the messages, printed". The file is not on your disk yet? The guides explain how to get it.
From the same family as Klarfile
To merge, split or sign the PDFs taken out of a message, Klarfile keeps the same promise, with the same design. To redact a document before sharing it, Klarmask. For an attached workbook, Klargrid.
And if you want to depend on no website
Klarinbox can be copied onto your internal server and works with no Internet access: it needs a web server, however small, and nothing else. Klarinbox on your intranet.
An email to open?
Nothing to install, nothing to create, nothing to accept.
How it works
Three steps. Everything happens on your machine.
Drop the message
A .msg, .eml, .emlx or winmail.dat, dragged onto the page. It is read by your browser and lives in the tab's memory.
Read it
Header, body, attachments, and attached messages, which open in turn. The technical headers are one click away.
Save what it holds
One attachment, or all of them in an archive. The files go from the tab's memory to your disk.
