How does PicUp improve clarity?
It prefers a Real-ESRGAN super-resolution model on your local GPU or CPU. If that is unavailable, it falls back to a faster enlarge-and-sharpen method. Photos are not uploaded.
Can large images fail?
When output is near or above about 16 megapixels, the browser may slow down or run out of memory. Try 2x first, or crop before enlarging. Failures are usually a damaged file, an unsupported format, or low memory.
