Frequently asked questions
Can an upscaler add real detail?
AI models predict plausible detail, which looks much sharper than simple resizing, but they can’t recover information that was never captured.
Why is AI mode limited in size?
Super-resolution is heavy; large images are processed in tiles and can be slow on phones. Use Classic for very large images.
