MIM to ICO Conversion: FAQ

What are MIM files?

MIM (Multi-Purpose Internet Mail Message) is a generic format used by some email programs to encode sent or received data. A MIM file can refer to the content of the email message or to its attachment. In both cases, opening such a file outside the email program which created it might be difficult. One handy option for handling MIM files is converting them to more widely available image format, such as JPEG.
