How to use this tool
Choose files to inspect names, sizes and detected formats. Detection uses leading signature bytes, such as %PDF for PDF. If an extension disagrees, check the source. Unknown does not mean corrupt, and detection is not a malware scan.
Check the input format and options with this example before using your own data. Random values, file sizes and presentation vary with the input and settings.
