Lossless scaling is a recording technique that preserves the original quality of an image or video, even when it is resized or scaled up. This is in contrast to lossy scaling, which reduces the quality of an image or video when it is resized or scaled up.
Lossless scaling is important because it allows you to resize or scale up images or videos without losing any of the original quality. This is especially important for images or videos that will be used for printing or other high-quality applications.
