Label object in image data set

I am trying to make a learning data set for F-CNN, but I can't seem to find somewhere how I label objects in the images. Is there a tool in matlab for this or should I drag them into paint and mark the objects, and then use it that way? I know it is a stupid question, but I have spend way to many days searching the internet with no luck. The images are .png.
