Geoid 18 help

I am new to the drone side of surveying and was wondering if anyone has been able to get a hold of the geoid18.tif file I have rs+ base and rover for my personal use and i have really enjoyed them, but at work we use Trimble which I been using most of my surveying career. We run a rtk drone at work and process with pix4d and have been having issue with the drone not aligning as we believe it should. I notice that emlid uses the tif extension for there geoids and was wondering if there is a way to actual get that file to import into pix4d? Trimble uses ggf extension and pix4d does not support.
