You should use Remere's Map Editor. It's the map editor that 99% of people use.

You will also need the Tibia 7.4 client so that RME (Remere's Map Editor) can load the sprites. I typically use Internet Archive and browse the old TibiaClient website, here:
Tibia download. All Tibia Clients download including legacy versions from 3.0 to 8.55. Useful for OTs and Tibicam movies. - Powered by UltimatumHost.com

You do not need to setup a server to view the map in the map editor.
