| Description | Many of us prefer to store emails in the MBOX format, which organizes all messages into one file. This format is intended for storing email messages on hard drives. In fact, a MBOX file is a long text file, in which messages are organized in a string, each message starting with “From”, which is followed by a space character and the sender’s email address. Initially, MBOX files were used on Unix. These files are supported by Qualcomm Edora, Microsoft Entourage, Thunderbird and Mozilla clients. |

Journalists, researchers, and legal teams convert MBOX archives to PDF to get a readable, portable record of email conversations from Thunderbird, Gmail Takeout, or macOS Mail.
MBOX is an open plain-text format that stores multiple email messages concatenated in a single file, separated by "From " lines. It is used by Thunderbird, macOS Mail, Eudora, and exported by Gmail's Takeout service. While technically readable as text, the raw format is impractical to share or present as documentation.
PDF (Portable Document Format) renders content identically on any device without requiring the original application. It is the standard format for sharing documents that must not be altered, accepted by courts, regulators, and archiving systems worldwide. Every major operating system includes a PDF viewer.
