Snagit is a screenshot program that captures video display and audio output. Originally for the Microsoft Windows operating systems, recent versions have also been available for Mac OS, but with fewer features. It is created and distributed by TechSmith, and was first launched in 1990. Snagit is available in English, German, Korean, and Japanese versions.
Snagit replaces the native print screen function with additional features. Newer versions allow batch capture of embedded items such as links, pictures, and multimedia. The user can set parameters and keyboard shortcuts to capture particular types of data, which are stored in a folder called "Catalog" by default. The software can also follow links in web pages, capturing the specified data from the linked pages.
Accessories extend its features. For example, Flickr Output enables the user to upload screen captures to a Flickr account.
