Frequently Asked Questions

What is a MIME type?

A MIME type is a string like 'text/html' or 'image/png' that tells the browser or client how to interpret and display a file. It consists of a type and subtype separated by a slash.

How do I find the MIME type for a file extension?

Type the file extension (e.g., .pdf, .webp) into the search box. The tool will show the corresponding MIME type and category.

What MIME type should I use for JSON?

Use 'application/json' for JSON data. For JSON with a specific schema, you can use vendor types like 'application/vnd.api+json'.
