2× vs 4× AI Image Upscaling Explained
The 2× upscaling option doubles the width and height of the image and is ideal for moderate quality improvements. The 4× option provides a stronger enhancement and is best for very small or low-resolution images.
Choosing the correct scale depends on your use case. For websites and documents, 2× is usually enough. For printing or large displays, 4× provides better results.
