Convert GeoTIFF to PNG/JPEG doesn't generate a picture with correct colour scale
ImageMagick's convert program changes PNG file format so that color/alpha info doesn't survive GDALGDAL_TRANSLATE Assumes Picture is Orientated North?Decompress a LZW-compressed GeoTIFFWhy result of merge of multiple raster is so big?GeoTiff to 16 bit tiff, png or bmp image for heightmapUInt16 only has 256 bucketsUsing gdal_translate and -scaleGDAL Translate with WMS Source tears rasterUnable to convert 3 band Spacenet dataset geotiff image to either jpg or png with gdalconvert png with alpha channel to GeoTiff
I have a GeoTIFF, when I open it on arch gist, it shows 2812.15 to 2846.09 colour range. My gdal_translate commend is gdal_translate -ot UInt16 -of PNG -scale 2812.15 2846.09 2812.15 2846.09 x.tif x.png Which generates a picture in 0 to 65535 scale. I know it's not possible to have Float32 with PNG. I'm looking for a way to get the picture with exact colour range as TIFF one or using another popular format to get that if it's not possible with PNG or JPEG.

What happens when you omit the -scale? Are you sure the cell values have actually changed? 0-65535 is the maximum possible range for Int16 data type, it's possible that this range is being shown due to lack of valid statistics. How does it look in a different package like ArcGIS (if you have it) or QGIS? PNG does support Int16 but JPEG does not that I know of support any pixel type other than UInt8 (byte)... What is wrong with the GeoTIFF that you need to convert it?

What happens when you omit the -scale? Are you sure the cell values have actually changed? 0-65535 is the maximum possible range for Int16 data type, it's possible that this range is being shown due to lack of valid statistics. How does it look in a different package like ArcGIS (if you have it) or QGIS? PNG does support Int16 but JPEG does not that I know of support any pixel type other than UInt8 (byte)... What is wrong with the GeoTIFF that you need to convert it?
