you can use www.remove.bg to remove backgrounds fast from any png
Nice. See I learned to do it the hard way on GIMP years ago for simple backgrounds, so I never bothered to look up an easier way. I'll keep this in mind for the future, though I dislike making accounts to use a service I can do myself.
you dont need an account to just remove the backgrounds :) you only need an account if you want to do additonal edits
