What to watch out for
Upscaling cannot invent detail that was never captured, so a very small or blurry source will stay limited. Large images take time and system resources, and performance depends on your hardware. Keep your originals safe, since an enlarged file should never replace the master. When quality matters, export a small draft first to confirm the result before producing the final file. Generated suggestions are for reference only, so verify anything that affects professional judgment or important data. Save a backup of the original file before large batch jobs, and keep an exported copy of key results in case the page or service becomes temporarily unavailable.
