Convert eml 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 EML files as you like.
Real MBOX output
Encoded by email, the same library the command-line tools use — not a renamed extension.
About EML
Internet Message Format
A single email saved as text under RFC 5322, with headers and a body, and attachments encoded as MIME parts. Thunderbird, Apple Mail and many other clients can open it. Convert an EML to read, archive or print a message without a mail client.
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.
