just make a calculation 16 pixels to 2 pixels = thus you are losing 14 MP
Ok it's not really working this way, but... changing the size of an image will ALWAYS alter the quality of your pics, you do have software which MIGHT do a better job reducing an image (XnConvert comes to my mind) but do not expect miracle, at all, as you are *shrinking AND mixing pixels... (*pixels are "unshrinkable", but you got the point as you are reducing the number of pixels)
If you call quality the lack of sharpness ➤ the unsharp filter might help Filters ➤ Enhance ➤ Sharpen (unsharp mask)
but other all, shrinking from 16MP to 2MP ➤ you are loosing 8 times the number of data... squared! (not sure about the squared one, though, my math are so way out)
But you know what I mean
