InstantMask

InstantMask is a lightweight and simplistic application that you can use to remove backgrounds from images in a friendly environment. It supports the PNG, JPG, JPEG and BMP formats.
The interface of the program is represented by a simple window with a plain layout. Opening an image file is done by using only the file browser, since the "drag and drop" method is not supported.
So, you can use two separate markers to draw around the area you want to keep and to move, respectively. Applying the new modifications is done with the simple click of a button.
In addition, you can zoom in and out of the picture, as well as save the resulted photo to the JPG file type. Unfortunately, there are no other options available through this tool. For instance, you cannot minimize InstantMask to the system tray area or make it automatically run at system startup.
InstantMask runs on a moderate quantity of CPU and system memory, has a good response time and quickly applies the new image modifications. We have not come across any problems throughout our testing; the app did not hang, crash or display error notifications.
All in all, InstantMask is a decent application for removing backgrounds from photos, although it has not been updated for a pretty long time.
