- Type a file extension (e.g. mp4) or a MIME type string (e.g. application/json) to filter the list in real time.

- Copy the MIME type string from any row for use in your code or configuration.
Frequently Asked Questions
- When do I need a MIME type?
- MIME types tell browsers and servers how to handle a file. You need them when setting Content-Type headers in APIs, configuring web servers, or building file upload features.
- Can one file extension map to multiple MIME types?
- Yes — some extensions like .xml or .js have multiple valid MIME types depending on context. This tool shows the most commonly used mapping.
- Where does the data come from?
- The mappings are based on the IANA media type registry, which is the official standard for MIME type definitions.
