Currently, ArcGIS provides support for 32-bit TIFFs, but the ability to include an alpha channel is only available when exporting maps. It would be extremely useful if all raster processing tools that generate a new raster (e.g., Copy Raster, Export Raster, etc.) could support writing 32-bit TIFFs with an alpha channel.
This enhancement would greatly benefit users who work with transparent raster datasets and streamline workflows across different applications.

Export raster to TIFF: add option to add an alpha-band for NoData values
perhaps they need to consolidated in some form or another
Hi @DanPatterson ,
thanks for the hint! I just upvoted that idea as well.
I had seen that idea before posting this one, I only created this new one because we are not specifically dependent on the value "0" for the alpha channel. But perhaps this value is always assigned by default when adding an alpha channel to a raster!? I'm not sure about that.
If so – how could the two ideas be merged?
@JesseCloutier would be able to assess if it is similar enough
Thanks for tagging me, @DanPatterson. I've pinged an ArcGIS Pro Ideas Manager to take a look at this conversation and make a determination when they next have an opportunity. All the best!
