Editing/Importing sprites question

[Ancient EviL]

So if I want to make a custom sprite or edit an existing one, what is the proper way to save the file? Because if I edit an existing sprite, for example, if i wanted to give the zombieman blue eyes, when I import it, there is white fill where there shouldn't be. How do I fix this?

Edit it as PNG, using any graphic editing software. For transparency, use actual transparent background. Then import the sprite into your wad and convert to Doom graphic format, using SLADE3.

How can I make a background transparent in mspaint? If it's possible.
