How to Image to Image as if using Grok, Gemini, etc?

Hello, sorry if this has been asked before, but I can't find if there's a true one to one method for local AI. I have a 4090 FE 24GB, along with 32gb of DDR5, trying to learn Qwen Image Edit 2511 and Flux with Comfy UI. When I use online AI such as Grok, I would simply upload a picture and make simple requests for example, "Remove the background", "Change the sneakers into green boots" or "Make this character into a sprite for a game", and just request revisions as needed.
