Frequently asked questions

How do I enlarge an image without losing quality?

Pick a scale factor (2x-4x) and an AI engine, then run; the tool reconstructs missing pixels instead of blurring them.

Do I need an internet connection?

Only the first run downloads a small AI model (about 1-5 MB). Later runs work fully offline.

Are my images uploaded to the cloud?

No. Upscaling runs on your computer, GPU-accelerated; your images are never sent to any server.
