What is MIME type?

When you are browsing the internet, you may have seen a file extension such as .pdf or .doc and wondered what the MIME type is. MIME stands for Multipurpose Internet Mail Extension.

The MIME type is the way that a computer knows what program to use to open your file. You can find out the MIME type of any extension by using an online tool such as CheckFileType which will list all extensions and their corresponding types.

Examples of MIME types

The most common ones are listed below:

  • HTML (Hypertext Markup Language) – Text documents with formatting information, links, images etc. Most modern web pages are in HTML format.
  • MIMIC (MIDI Files) – Sound recordings made for music synthesizers used on computers; may contain lyrics, sequencing data, and other information relevant to playing back instruments on digital keyboards for example.
  • MPEG (Audio/Video) – Recording compressed into an MPEG file.
  • PDF (Acrobat Portable Document Format) – A PDF document can be a scanned copy of a paper book or magazine, for example. It’s more likely to include text and images than other formats like JPEG.
  • MSOffice 0 Microsoft Office documents such as MSWord/Excel/Powerpoint files, which are shown as .xlsx, .docx, .pptx, etc…
