I have a large flat plane with almost 3k faces but it could be 1 huge face. How can I do it?
3 Answers
give it a decimate modifier and play with the ratio until faces count is very low like 3:
then apply the modifier and go in edit mode and delete the superfluous edges:
with "limited dissolve"
Deselect All in Edit mode. ⇧ Shift CLICK all 4 corner vertices. ⎈ Ctrl I to invert the selection then ⎈ Ctrl X to delete them with limited dissolve.

1.) Go tab into Edit Mode
2.) Press 1 to switch to Vertex Select mode
3.) Press A to select all vertices
4.) Then Shift+LMB all 4 corner vertices to deselect them
5.) Press X & choose Dissolve Vertices
