I am on my phone, how do I save maps, blueprints, and floor plans that I find online?

I'm on my phone if that's relevant. I always find awesome maps, blueprints, and floor plans that I can easily adapt to whatever municipal building, etc. I'm building. I'm just wondering how I can use these maps as a source of inspiration in a way that it is as easy as looking at one of the many pictures I have saved. I know even if I downloaded them they'd be hard to read.<br><br>I've thought of maybe making my own blueprints and floor plans as part of my world building process, but that would be a tremendous amount of work to say the least. It also doesn't allow me to easily visualize different possible variations of the building.<br><br>I use Google on a Samsung Galaxy A52 5G. If you can on your phone, then I am also expecting you to be able to do on your phone.
