Upscaling is most useful when it solves a specific display or print-size problem.
Use the before-and-after preview to judge edges, faces and texture before keeping the result.
It estimates plausible detail from the source; it cannot restore information that was never captured.
Use the smallest scale that meets the need for a more natural result.
Very blurry or heavily compressed sources can produce invented texture. Review important details before using the output.
Usually yes for web publishing, because upscaling increases pixel count and file size.
Choose a focused workflow.
Enlarge old photos and preview a clearer version before downloading.
Prepare anime image upscaling pages for later model-specific support.
