Convert Image to Pyramidal TIFF
Example:
gdal_translate -co "TILED=YES" original.tif output.tif gdaladdo -r average output.tif 2 4 8 16 32 64
The first command will tile the image which helps with performance. The second will add overviews: 2 4 8 16 32 64 (each number is a split level (so this will create 6 levels - you can create more but making a tile smaller than 256 by 256 is pointless). The final image in the example will be output.tif.
