MIME Type Detector

This node detects the MIME type (aka. “media type” or “content type”) of given files or binary data by looking at the actual data (i.e. not the file extension).

For example, for a PNG image it will return image/png, for a PDF file it will return application/pdf.

Technically the MIME type detection works mostly with “magic patterns” which appear at the beginning of files and which can be used to deduce the file type. For example in case of PDFs, the magic pattern would be %PDF appearing at the beginning of the file.
