Mat2 is a tool designed to anonymize various file formats by removing metadata. Metadata includes information embedded within files that may reveal sensitive details about the file’s creator, location, or editing history. This metadata can pose privacy risks when sharing files, especially in scenarios where users want to protect their identity or sensitive information.

- Metadata Removal: Mat2 removes various types of metadata embedded within supported file formats. This includes information such as author names, creation dates, GPS coordinates, device information, editing history, and more. By stripping this metadata, Mat2 helps users protect their privacy and anonymity when sharing files.
