Verify file integrity and identify spoofed file extensions. This utility reads the initial bytes of any uploaded file to determine its true MIME type.
The tool renders the first 128 bytes in a styled Hexadecimal and ASCII matrix, letting you inspect headers. It matches bytes against a library of signatures (e.g. `89 50 4E 47` for PNG).
If a file header is corrupted or truncated, the Header Doctor will repair the initial bytes for popular extensions and let you download a working file.
