About:

Not sure what format your file is? Just upload it and let our server analyze the file's binary signatures to identify what exactly format your file is.

The analysis results will show all possible file formats. For example: If you submit a DOCX file, the analysis results will identify the file both DOCX format and ZIP format. This is because DOCX documents are stored in Open Packaging Convention (OPC) packages, which are ZIP files containing XML and other data files. A DOCX file can be renamed to a ZIP file and opened by WinZIP software.

Detailed information (such as image geometry, video bitrate or audio sampling rate.) will be listed behind if our analyzer can get it.
