What Does "Enhance Image Resolution" Mean?
Enhancing image resolution refers to the process of increasing the clarity and detail of an image. Higher resolution images contain more pixels, which means they can display finer details. When you enhance image resolution, you are effectively increasing the pixel count, which leads to a sharper and more detailed image. This process is particularly useful for low-quality images that need improvement for professional use, such as in marketing materials or social media.
