🔍 Detection Result
Advertisement
Upload any file to identify its type by inspecting the file extension and leading byte signature. Results include filename, detected type, confidence reasoning, size, and MIME hint — all running entirely in your browser.
Detection uses both the filename extension and the file's leading bytes (magic numbers) where available, so misnamed files are identified correctly.
Results are based on defined signatures and rules — no guessing, no AI. Ambiguous cases are described plainly with the evidence shown.
