FAQ
How does upscaling work?
It uses algorithms to intelligently add pixels, attempting to preserve detail and reduce blur.
Does it improve quality?
It can make images appear sharper, but cannot add detail that was not in the original.
What is the maximum size?
Browser-based tools have memory limits. Very large upscales may fail.
