Extract text from email files (MIME)
To convert MIME emails to another format, you need Microsoft Outlook or other Encoded software.
To convert other file formats to the "Encoded Email Message" file type, you need software like Microsoft Outlook or a similar tool.
The .mime file extension represents a saved email message formatted according to the Multipurpose Internet Mail Extensions (MIME) standard defined by the IETF. These files act as raw text containers that bundle email headers, HTML or plain text bodies, and file attachments into a single document. Historically used by systems like the Schools Interoperability Framework (SIF) for student data exchange, they are most commonly handled today by desktop email clients like Microsoft Outlook and Mozilla Thunderbird.
Despite being an internet standard, the .mime format has severe disadvantages for everyday users. Because legacy email protocols only supported 7-bit ASCII text, .mime files must encode binary attachments (like images or PDFs) into text using Base64. This encoding bloats the file size by approximately 33%. Furthermore, .mime files are not supported by modern web browsers natively. If you try to open one in a standard text editor, you will be confronted with thousands of lines of unreadable Base64 gibberish instead of your actual document.
To make this data accessible outside of a dedicated email client, you must convert it. For archiving and universal reading, convert .mime to PDF. To import the message into a different email system, convert it to EML or MSG. If you just need the text for a website, convert it to HTML.

If you want to convert MIME file to PDF, JPG, MP4, TEXT, EML, MSG, PNG, HTML, JSON, BASE64, HEX or BIN, you can use Microsoft Outlook or similar software from the "Email Message Archive" category. In the File menu, look for Save As… or Export….
To convert CER, BIN, PEM, DER, KEY, P7S, PFX, ENC, P12, BASE64, P7B or HEX files to MIME, try Microsoft Outlook or another comparable tool in the "Email Message Archive" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MIME converter.
