I have an image, it's a black outline with a yellow inside. How do I convert it to just simply black and white. I've tried grayscale, but it turns into black and gray. I've been trying to figure out how to do this for two hours now, I give up. How can this simple thing be done?

And after applying the "Desaturate" filter, open Filters Editor, click on the filters name and increase K2 entry in Composite (up to 2 for example) which will increase contrast and change grey to white.
