I have a RGB 3-band GeoTiff which gives me a nice looking when loaded in ArcGIS. Now i want to convert it to a simple colored image. My goal is to have an image which can be displayed the same in different software. (I know that i can change symbology of raster in every software, but i don't want to do that.) I have no analysis or processing need for this image, and only its view is important for me. How can i do that in ArcGIS?
What i have done: using Copy Raster tool, but unfortunately 'RGB to colormap' option is grayed out for this raster. I also tried Raster Calculator to add band values together, but output is not colored.

QGIS gets the images from the ArcGIS server with this kind of requests
The result is an image that is rendered with colors and there is nothing that can be done on the QGIS side at this moment. Colors cannot be converted into raw data.
I guess that for accessing the raw imagery the URL should be modified somehow but unfortunately I do not know in which way.
I noticed also that the normal QGIS Identify Features tool tries to query the pixel values at a clicked point but something goes wrong. The Debugging/Development tool shows that requests are sent
However, QGIS shows just a message "No features found at this position". But if I copy a request from the debugging tool and paste it into browser I can see that the server does answer. For example:
Result:
{"objectId":0,"name":"Pixel","value":"-0.0235954","location":{"x":-121.132076,"y":38.145169000000003,"spatialReference":{"wkid":4326,"latestWkid":4326}},"properties":null,"catalogItems":null,"catalogItemVisibilities":[]}

You need to change the bit depth (pixel type) to 8_BIT_UNSIGNED for this.
