A short companion for MIME Types: when it is useful, what it expects, and what to check before using the result.

What it does

Look up the MIME type for a file extension, or work backwards from a type to the extensions it covers.

Use the tool

Open MIME Types, add the input the tool asks for, run it, and check the output before using it elsewhere.

Input and output

  • Input: text.
  • Output: text.
  • Category: Web.

Privacy and processing

Processing happens locally in your browser. This tool does not upload the input to ilham.dev.

Questions

Why does one extension have two types?

Because of history. .js is text/javascript today, but application/javascript still appears in older configurations, and servers generally accept both.
