How can I subtly reassure my female friends that I DON’T like them romantically?

They get awkward if I become too friendly, or ask to hang out with them. I have absolutely ZERO interest in dating any of them. I just wanna be able act around them as I would with my male friends without them assuming I’m trying something. I feel like directly saying “jsyk I only see you as a friend” could make things super awkward if I’m misinterpreting things and they actually don’t think I’m interested in them. Any advice?
