MIME Type Lookup - File Extension Finder
Instantly find the correct MIME type for any file extension, or vice versa. Our Free MIME Type Lookup tool is an essential offline dictionary for backend developers and server admins.
What is the MIME Type Lookup Tool?
When configuring web servers (like Apache or Nginx), writing file upload endpoints, or setting HTTP headers, you must define the correct MIME (Multipurpose Internet Mail Extensions) type for files. For example, a JSON file is `application/json`, but what is the MIME type for an MKV video or a WOFF2 font? This utility acts as a lightning-fast, client-side dictionary. You can search by file extension (e.g., '.pdf') to get the MIME type, or search by MIME type to see associated extensions. Because the database is loaded locally, searches are instantaneous and completely private.
