What is the alpha convert node for?


I tried to get some information on the internet regarding the ‘alpha convert’ node in compositing nodes but was not successful.
Can someone explain please what it does or what it is for?


Alpha can be either straight, or premultiplied by the color channel: http://www.cgdirector.com/quick-tip-straight-alpha-vs-premultiplied-alpha/

In the event you have one type, and are doing an operation that needs the other type, you can drop the alpha-convert node on the wire between the source and operation and it will do the conversion for you.
