Frequently Asked Questions
- What is an MBOX file?
- MBOX is a standard format for storing email messages. Each message starts with a "From " line, followed by headers and the message body. Gmail, Thunderbird, and Apple Mail all support this format.
- Does it extract email body text?
- This converter focuses on email metadata: date, sender, recipients, and subject. Extracting full body text from MBOX files requires handling MIME encoding, which is planned for a future update.
- How large a file can I convert?
- Files up to 50 MB are supported. For very large archives, the conversion may take a few seconds. If your file is larger, consider splitting it first.
- Is my email data private?
- Yes. All processing happens in your browser. Your emails are never uploaded to any server.
