Step 1
Open your messages
Drop files or a folder here
Choose up to 2,000 message files. They're read in this browser.
Where to find these files
Outlook — drag the message onto the desktop, or open File → Save As, for a .msg.
Apple Mail, Thunderbird — drag the message into a folder, or open File → Save As, for an .eml.
Gmail — open the message and pick Download message from the three-dot menu.
A zip — drop it in whole, and every .eml and .msg inside opens as one list.
A whole mailbox — open a .mbox in the MBOX viewer or a .pst in the PST viewer.
No file handy? . For routing and authentication details, use the email header analyzer.
Questions, answered.
No. Each attached file is listed with its name and rough size so you can see what came with the message, but the file itself is never kept. Open the message in Outlook for a .msg, or in Apple Mail or Thunderbird for an .eml, to get the file.
