Blender rescaling rendered images issue -

any appreciated, thanks.

your answer isn't directly related blender, since you're resizing image inside microsoft paint, program manage how pixels stored/rendered on screen , in of cases, shrinking or increase resolution of image, mean you're going lose detail/quality, try image manipulation program , check results, there algorithms perform resampling of image, each of them performs mathematical operation on pixel, approximation, multiplication between neighbors pixels , on. different programs have different features this.
