Seting 0 values in GeoTIFF to nodata using GDAL?

Question

Is there a way to set all the 0 value pixels on a raster to nodata using GDAL?

I would like to use fillnodata to fill some holes, but holes are set to 0, so I need to delete them first

You could try something like this with gdal_translate

gdal_translate -of GTiff -a_nodata 0 input.tif output.tif

Note: This only works if the raster does not have existing nodata values. It will set zero to be nodata, but existing nodata values will no longer be considered nodata. – Sheldonfrith Apr 25 '23 at 13:15
