Is it free and private?
Yes. Upscaling runs in your browser — your image is never uploaded.
How does it work?
An AI super-resolution model enlarges your image while reconstructing detail and sharper edges.
How much bigger can it go?
Typically 2×, and 4× for smaller images, depending on your device's memory.
Why is it slow on large images?
All the AI runs locally on your device; smaller inputs upscale much faster.
Why is the first run slow?
The model downloads once on first use, then it's cached for next time.
What images work best?
Smaller photos, logos and art/game assets; very large inputs may be limited for performance.
