Cutting-edge AI that runs faster than reading a file extension - and is correct more often.

How It Works

1
Drop a file
Drag in any file or pick one from disk. Batch a folder if you like - they all stay local.
2
Magika reads the bytes
A small deep-learning model inspects the first few hundred bytes and predicts the true type.
3
Verdict in <1s
Get MIME type, extension, confidence score, and a link to the format guide. Export as JSON when you need to.

Detection that doesn't trust the filename.

An extension is a hint. A MIME type is a guess. We read the bytes - that's the only thing that can't lie.
