Metadata Removal Tools

Metadata Removal Tools is a type of privacy software built to protect the privacy of its users by removing potentially privacy-compromising metadata from files.

Metadata can be found in many types of files such as documents, spreadsheets, presentations, images, and audio files. They can include information such as details on the file authors, file creation and modification dates, location (GPS), document revision history, thumbnail images and comments.

Since metadata is sometimes not clearly visible in authoring applications (depending on the application and its settings), there is a risk that the user will be unaware of its existence or will forget about it and, if the file is shared, private or confidential information will inadvertently be exposed. The purpose of metadata removal tools is to minimize the risk of such data leakage.
ExifCleaner

ExifCleaner

ExifCleaner is an open source program allowing you to remove metadata from images, videos, and PDF documents, making them safer and smaller in size. There are instances when attackers will target GPS and device metadata so they can better profile their victims allowing them to tailor phishing attacks, for example. An app like ExifCleaner is designed to take that upper hand away from the attacker. Since it is removing some data, it also can help save some space on your drive.
