How To Reduce Texture Size of a Figure?

In Daz Studio, If I want to reduce Texture size, what will be best way. How I can do that?

If a character, say Victoria 9 has 8K skin texture, is it possible to save it as 4K or 2k? 

There is a tool V3 Scene optimizer, that do it, but I am unable to save that texture for future use. also, i found, sometime it doesn't do much.

    Doesn't do much in what sense? Did it not reduce the texture resolutions, or did reducing texture resolutions not have much impact on your render times? Have you tried saving a material preset with the reduced textures?

    Technically, yes... you just locate the texture maps in runtime\textures folder from the surface slots in Surfaces pane. Downsize the maps with image editor like Ps, Affinity, Gimp, even some Image Viewer, etc... Save the map as a copy, re-assign it to the slot. Save a Material Preset as you wish. BTW, V9 only has 8K maps in Detail Normal slot, not all....

    Scene Optimizer can do the same work. It saves the downsized maps with suffix in their original locations of runtime/textures... You may save Material Presets after optimization as Gordig said. And whether it does much or not depends on the "level of division" you set in Scene Optimizer, which will or will not significantly influence the VRAM consumption when rendering....

    It's no different than real life. Trimming the fat makes a huge difference.

    There was a free script from a while back that was in one of the threads. It can reduce selected maps by half, quarter or eighth and save them separately for later use. Although the script is free I probably don't have a right to link it directly. It's in this thread here.

    Well, I mean, somethime it doesn't do much and there was a scenario, when the result scene size was not changed at all.

    Whay do you mean by "Scene size"?
    The size of the savefile or how much the scene takes RAM and VRAM?

    Thanks a lot Crosswind. So I open the files which are in Texture folder and then use photoshop to change the dimensions from 4096 By 4096 to any smaller size like 2048 By 2048 and save them in same format. Correct me if I am wrong. Also here you mean (V9 only has 8K maps in Detail Normal slot, not all....) Normal Maps right?

    Not all normal maps: specifically the detail normal map. The regular normal map is 4K like the rest of the maps.
