Why is the preview image better quality than the rendered one? First pic is final render, second pic is what is shown on the compositor, can tell me why the one on the compositor has better quality?


This is rendered in Blender 2.9
If you notice , you have pluged the output of your denoise node in your viewer , if you want the results to be similar to the viewer node output , then you should also plug that into the composite node , the viewer node is only for preview and compositor makes changes in the render itself
