Convert msg to mbox
Converted on your device. Files never leave this tab.
Nothing is uploaded
The converter runs inside this page. Cut your network after it loads and it still works.
No account, no daily limit
No sign-up, no daily limit, no watermark, no queue behind other people's files. Batch as many MSG files as you like.
Real MBOX output
Encoded by email, the same library the command-line tools use — not a renamed extension.
About MSG
Outlook Message
Microsoft Outlook's format for a single saved email, a binary Compound File holding the message properties and attachments. Convert MSG to read Outlook messages on a Mac, a phone or any computer without Outlook.
About MBOX
MBOX mailbox
A plain-text format that stores many emails in one file, each starting with a line that begins with 'From '. Thunderbird keeps folders this way, and Google Takeout exports Gmail as MBOX. Convert from MBOX to read or search a mailbox export without importing it into a mail client.
