Tool to find metadata and hidden information in the documents.

FOCA is a tool used mainly to find metadata and hidden information in the documents it scans. These documents may be on web pages, and can be downloaded and analysed with FOCA.

It is capable of analysing a wide variety of documents, with the most common being Microsoft Office, Open Office, or PDF files, although it also analyses Adobe InDesign or SVG files, for instance.

These documents are searched for using three possible search engines: Google, Bing, and DuckDuckGo. The sum of the results from the three engines amounts to a lot of documents. It is also possible to add local files to extract the EXIF information from graphic files, and a complete analysis of the information discovered through the URL is conducted even before downloading the file.
