Hi,

I'm needing to change the bit depth of a PNG that's at 24 to 16. The image needs to remain a PNG and maintain its current dimensions. I've already tried multiple things I found online to change it, but it still says "Bit Depth: 24" (see image) no matter what I try. How would I go about doing this, if at all possible?

24 bits is 8bits/channel, you can go to Image>Color Mode and change it to 16 bits/channel, then save it?

When I change it to 16 bits/channel and go look at the image properties, it says "Bit depth: 48." I need it to be "Bit depth: 16."

16 bits per channel = 48 bits (16 x 3)

8 bits per channel = 24 bits (8 x 3)

Just different ways to express the same thing.
