Identify Your Files: MIME Type Lookup

Ensure your web servers and applications handle files correctly by serving them with the proper MIME type.

What is this tool?

The MIME Type Lookup tool is a search utility that maps file extensions (like .pdf or .json) to their official Multipurpose Internet Mail Extensions (MIME) type (like application/pdf or application/json).

Step-by-Step Guide

1. Enter Extension: Type the file extension (e.g., csv) in the search bar.
2. Search: The tool instantly queries its database.
3. Copy MIME Type: Copy the correct MIME type to use in your headers or code.

Practical Use Cases

• Web Server Configuration: Setup Nginx or Apache to serve custom file types correctly.
• API Development: Ensure REST APIs set the correct Content-Type headers for downloads.
• HTML Forms: Properly configure the accept attribute on file upload inputs.
