Your image has 5 channels and png format does not support that. Just to make sure that the the input image is generally OK try gdal_translate -of GTiff -co tiled=yes -co compress=deflate test.ecw test.tif. If is ok have a new try with png format by selecting three bands for RGB with the -b parameters.

Your image has a size of 16000 by 24000 pixels and the software must always open the whole PNG image even if it would only need a small subset. | |
