A sanitized file is a file which has been processed to remove hidden contents such as embedded objects and potential exploits, while preserving the visible contents of a file. The sanitized file will maintain the format and file extension of the original file (unless it has been explicitly set up to be converted to another type of file). For example, a sanitized PDF will maintain the PDF format, and the .PDF extension, and will be accessible by a PDF reader.
Some of the actions performed as part of sanitization include:
Removing all attachments and document action
Removing all annotations
Removing java script and other scripts
Making the form fields present in PDF file un-editable/in-accessible so that the user cannot update the values
Recent versions of MetaDefender Kiosk allow administrators to create sanitization processes as part of the file type conversion process. For more information refer to the user manual:

MetaDefender Kiosk supports sanitization for many of the most common document files types. If you have a requirement for a file type that we do not currently support, log a ticket with us on the OPSWAT portal to let us know. Though we cannot make any commitments as to when we will add support, we are always looking to add new file types that are commonly used by our customers.
