I want to crop a picture buti dont want touse a the normal square/rectangle to crop it because its an irregular thing that i want to crop. So, its a picture of a giraffe and i want to crop it where its just the giraffe with NO background at all. So i think i need somethingwhere i just trace aroud thegiraffe and then it cuts it like thatbut i dont know what to use to do that. Please suggest something free and preferrably online (no download). Thank you.
