What this is actually doing.
You need more pixels, not a new image. A 1200 × 800 image becomes 2400 × 1600 at 2×.

Add detail while making this image larger.
This is a genuine AI upscale, not ordinary browser stretching. The model runs on your device and creates a 2× PNG without uploading your image.

Useful to know
Four things worth knowing.
Where it stops.
It cannot recover detail that was never captured. Faces, lettering and fine edges can still need a close look.
What to inspect.
Look at the result at 100%. If the added detail feels invented or crunchy, keep the original instead.
Worth knowing.
The model downloads into your browser and runs there. Your image is not uploaded to OutMonkey.
