I mainly use this to screenshots pictures in websites that don't have a choice to save after right-clicking on the pic, screenshots pictures with headlines or screenshots manga/manhwa/manhua online pictures (because if you right-click & choose open image in new tab, it's a long pictures & not just a specific picture of what you want)

It's a simple & effective tool to use. Right click the picture, scroll down & expand to find your choices. It saves in png & I don't know if other types are available or not.
