The minimap is a small overview shown in the corner of the map, so visitors keep their bearings while they're zoomed in. Each level can have its own minimap image — and giving it a simplified picture often reads better than reusing the full map.
Turn the minimap on
The minimap is controlled by a single switch. On your map's Settings tab, under General, turn on Minimap ("Show a small overview map in the corner"). With it off, no minimap appears no matter what images you've set.
Set a minimap image per level
-
Open the Levels tab
Edit the map and go to Levels.
-
Find "Minimap image (optional)"
Under each level, below the main map image, there's an optional Minimap image field with its own Upload button.
-
Leave it blank to reuse the level image
If you upload nothing, the minimap simply shows a smaller version of that level's main image. That's often perfectly fine.
-
Or upload a simplified overview
Upload a cleaner, low-detail version — just the outline and key blocks — for a minimap that's readable at that tiny size.
Why a simplified image can be better
At minimap size, a full, detailed map turns into an unreadable smudge. A stripped-back version — the building or site outline, a few big colour areas, no small labels — communicates "you are here, in the whole place" far more clearly. Think of it as a thumbnail sketch, not a shrunk copy.
Format and size
Use the same accepted formats — SVG, JPG or PNG. Because it's shown small, a minimap image doesn't need to be large; an SVG or a modest PNG is ideal. If you're making a simplified version anyway, exporting it as SVG keeps it crisp and tiny.
Per level, on purpose
Set a minimap image on each level you want one for. Levels you leave blank fall back to their own main image, so you can mix — a custom minimap on your busiest floors, the default elsewhere.
