I have a hillshade which I want to compress using JPEG compression:
gdal_translate -co COMPRESS=JPEG -co TILED=YES /home/bera/Drives/ssd1/Hillshades/testhillshade.tif /home/bera/Drives/ssd1/Hillshades/testhillshade_JPEG.tif
Input file size is 25000, 35000
Warning 1: /vsimem/gtiffdataset_jpg_tmp_0x55c683c3bb30: NBITS=32 is invalid for data type UInt16. Using NBITS=16
ERROR 1: JPEGSetupEncode:BitsPerSample 16 not allowed for JPEG
0...10...20.ERROR 1: JPEGSetupEncode:BitsPerSample 32 not allowed for JPEG
.ERROR 1: An error occurred while writing a dirty block from GDALRasterBand::IRasterIO
ERROR 1: JPEGSetupEncode:BitsPerSample 32 not allowed for JPEG
ERROR 1: JPEGSetupEncode:BitsPerSample 32 not allowed for JPEG
I dont understand what the error is telling me.

Why doesnt it work?
