Frequently Asked Questions
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard identifier used to indicate the nature and format of a file. It consists of a type and subtype separated by a slash, such as "image/png" or "application/json". Browsers and servers use MIME types to decide how to handle files.
How do I find the MIME type for a file extension?
Switch to "Extension → MIME" mode and type the file extension (without the dot) into the search box. The tool will immediately show the corresponding MIME type. For example, typing "pdf" will return "application/pdf".
Can I search by MIME type to find file extensions?
Yes. Switch to "MIME → Extension" mode and type part of the MIME type string, such as "image" or "video/mp4". The tool will list all matching extensions, which is useful when you know the content type but need to know the file extension.
