Extension MIME type Category Copy

MIME types for modern formats are registered with IANA, so the list is a practical reference rather than the whole registry. The same extension can have more than one type, for example .js may be sent as text/javascript or the older application/javascript, and what a server sends is what the browser enforces.

What Is MIME Type Lookup?

The MIME Type Lookup finds the content type for a file extension, and the extensions that use a given type. Search either way, filter by category from image to font, and copy the value for a server block or an upload validator.

Who Uses the MIME Type Lookup?

Web developers use it when a file will not play or will not apply, which is usually a content type the browser is enforcing. DevOps and email teams use it to set the right type in nginx, Apache, or an upload handler.

How to Use the MIME Type Lookup

  1. Type an extension like png, or a type like image/png.
  2. Filter to a category if you want a shorter list.
  3. Copy the type into your server or upload config.
