What is a MIME file?

A .MIME file is a saved email message or encoded data package. The acronym stands for Multi-Purpose Internet Mail Extension. The Internet Engineering Task Force created this standard to allow systems to send text, images, audio, and video as email attachments over the internet. When you save an email to your computer, programs often store the message and its attachments as a single .MIME file. Because the extension has multiple possible meanings, .MIME files are also occasionally used to store student record data for the Schools Interoperability Framework (SIF).

How to open MIME files?

Standard desktop email clients usually open .MIME files automatically. You can use software like Microsoft Outlook, Mozilla Thunderbird, or Winlink Express. Programmers can also manage and create these files using command-line tools and libraries like mime-construct. Since a .MIME file is essentially a text-based format, you can inspect the raw file structure with a text editor like Notepad++. However, the attachments will look like large blocks of random text characters.

Identifying and converting MIME files

If you are unsure what your specific file contains, viewer.online/mime analyzes .MIME files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If you need a more common format to share with colleagues, we recommend converting your .MIME file to a .PDF or .EML format on convert.guru.

Summary

Because .MIME files use the known MIME format, viewer.online/mime can safely open and display them online, eliminating compatibility problems.
