I need to convert a GeoTIFF image to PNG format with "NoData" pixels in the original image being transparent in the output.

Is there any tool particularly in ArcGIS ArcToolbox or GDAL for this purpose?

Thanks!

Cheers, Alex

you can achieve it with this way:

first run this code:

for %i in (*.tif) do gdal_translate -of GTIFF -a_nodata 0 %i %~new_ndata.tif

then:

for %i in (*.tif) do gdal_translate -of PNG -scale -co worldfile=yes %i %~cnvt.png

i hope it helps you...
