Frequently Asked Questions
- What is a MIME type?
- A MIME type (media type) tells browsers and servers how to handle a file, such as image/jpeg for JPEG images.
- Where does the data come from?
- From a built-in reference list of common file extensions and their standard media types. It runs entirely in your browser.
- Is this tool free?
- Yes. It is free to use and does not require an account.
- Why is my extension not in the list?
- The list covers common types. For rare or custom types, check the IANA media types registry.
