🕵️ File Type Detector (Magic Bytes)
Reads the first bytes of a file and checks them against known file-signature ("magic number") patterns to identify its real type — regardless of what its extension claims. Handy for spotting a renamed or mislabeled file. Nothing is uploaded; only the first 32 bytes are read, locally.
