❓ Frequently Asked Questions

What is a MIME type?

A MIME type (Multipurpose Internet Mail Extensions) is a label used to identify the type of data contained in a file or transmitted over the internet. It tells browsers and servers how to handle the content.

Why is compressible important?

Indicates whether the file format benefits from compression (e.g., gzip). Text formats (JSON, HTML, CSS) are compressible; images/videos usually are not.

How does the local file detector work?

It reads the first few bytes (magic bytes) of the file in your browser to identify its true MIME type. This is more reliable than the file extension. No data leaves your device.

What is the difference between `application/octet-stream` and other types?

`application/octet-stream` is the generic binary data type. It's used when the server or browser doesn't know the exact format.

Where does the data come from?

Our database combines official IANA assignments, Apache's mime.types, and Nginx's mime.types for maximum accuracy.
