A GeoTIFF consists of a TIFF image accompanied by a world file (.tfw) that contains georeferencing information to locate the raster in the appropriate position. The steps described in this article explain two methods to export a raster, map, or layout to a GeoTIFF format with ArcGIS Pro.
Using the Export Tool
This method is valid when exporting an existing raster that can be already displayed on the map, and thus is currently georeferenced. Taking that into account, the output raster with a TFW will be automatically generated with the raster, which both compose the GeoTIFF file.
Using the Export Map/Layout tool
If it is necessary to share a map or layout as a GeoTIFF file, this method will be useful.
