Frequently asked questions
Is my file uploaded anywhere?
No. The model runs entirely in your browser — your file never leaves your device.
How long does it take?
Typically about 1.8 seconds once the model is ready.
Does it work offline?
Yes, after the first run caches the model. No connection is needed afterward.
What do I need to run it?
A modern browser. WebGPU is used when available for speed, with an automatic WASM fallback otherwise.
Is it free to use?
Yes — AI Face Restore is completely free. No account, no watermark, no credits, and no usage limits.
Do my files or prompts ever leave my device?
No. Everything runs locally in your browser via WebAssembly/WebGPU — there is no server that receives your files, prompts, or results.
Which browser and hardware do I need?
A modern browser. Chrome and Edge get WebGPU acceleration for the fastest results; Firefox and Safari run via WebAssembly. This tool downloads nothing and runs on any device.
Can I use the results commercially?
Yes. You own everything you create — NSS makes no claim to the images, videos, or text you process or export.
Does it work on mobile?
Yes — it runs on phones and tablets too, since there is no model download.
