AI Image Upscaler
Upscale and sharpen images 2× with AI.
Make small or low-resolution images bigger and sharper. This AI upscaler doubles the resolution and reconstructs detail using a super-resolution model that runs entirely on your device — your image is never uploaded. The model downloads once on first use; larger images take longer and use more memory.

Upscale 2× with AI — runs on your device.
The first run downloads a one-time AI model (a few MB). After that it runs entirely on your device — your image is never uploaded. Large images take longer and use more memory.
Runs entirely in your browser — nothing is uploaded.

Frequently asked questions
Is it really free and private?
Yes — the upscaling runs in your browser on your own device, so it's free with no sign-up and your image is never uploaded to a server.
How much does it enlarge?
It upscales by 2× (e.g., 500×500 → 1000×1000) while reconstructing detail, which looks far better than a plain resize.
Why is the first run slow?
The AI model (a few MB) downloads once and then is cached. Processing time also depends on the image size and your device — a GPU makes it much faster.
