GeoTIFF viewer
Open a GeoTIFF (.tif / .tiff) as a map in one drop. Free for Mac and Windows. Drag and drop; files stay local. Preview ignores georeferencing — this doesn't.
How · .tif / .tiff
Drag it open on Mac or Windows
Drag the .tif into NimbleMap (or right-click › Open With). It sits under or over your other layers. Click a cell to read its value; colour by value with a legend.
Why not a browser tab or QGIS
Free, local, and enough for a look
Preview and Photos open a GeoTIFF as an ordinary image and ignore where it belongs on Earth. Browser GeoTIFF viewers are fine for a peek; large local files and stacking with a Shapefile or CSV work better on the desktop. You do not need QGIS just to see where the image sits.
