File Identifier

Drop in files to identify them by their contents, the way the file command does. This runs libmagic, compiled to WebAssembly, in your browser; files never leave your device.

Uses wasmagic 1.0.11, a WebAssembly build of libmagic. Files up to 16 MB are read in full; for larger files, only the first 7 MB are checked, which is how much the file command reads.
