Convert MBOX to XML

Fast, free, and secure MBOX to XML conversion. No registration required.

Stop uploading your mbox files to random websites. Xonvert converts to xml right inside your browser — 100% offline. The Mailbox File standard (maintained by Unix) provides simple concatenated format for email archive and migration. XML Document (W3C's format) delivers self-describing with schema validation, extensible for any domain — making this conversion highly practical. Mailbox File dates back to 1975, while XML Document arrived in 1998 with more modern compression technology. Need to convert the other direction too?
