The only supported 4 and 8 bit format is colour, what I found online was the 16 bit format doesn't work.


Interesting. The 16 bit format is interesting, because it stores partial color values. However, it certainly 'works'. 4 and 8 bit have palettes, anything higher, doesn't. My image processing articles show how to convert 24/32 bit to greyscale, making it work with 16 bit is pretty easy.

Does anyone know if there is a gray scale palette already in the system so I wouldn't have to make my own?


No, a palette is just a palette.

I don't want/need colour and size does matter. I want to keep it to 8 or maybe 4 bit format.


I'd be inclined to convert to 24 bit, convert to gray with a color matrix, and convert back. I'm not sure which would be faster, but that seems less error prone.
