If you have QGIS installed, you will also have GDAL installed. The GDAL programs will be located within the QGIS installation directory, usually within the "bin" folder. As an example:

C:\Program Files\QGIS 3.24.1\bin

The GDAL programs should be ready to use as they are. For example the following batch file will use "gdal_translate.exe":

set gdal_translate="C:\Program Files\QGIS 3.24.1\bin\gdal_translate.exe"
%gdal_translate% <conversion_commands>

However if you receive errors similar to "PROJ: proj_create_from_database: Cannot find proj.db" you should add this environment variable to the top of the batch file (Note: do not use quotes "" in path):

set PROJ_LIB=C:\Program Files\QGIS 3.24.1\share\proj
set gdal_translate="C:\Program Files\QGIS 3.24.1\bin\gdal_translate.exe"
%gdal_translate% <conversion_commands>
