Common use cases
Why it’s different
100% Private
Every model runs in your browser. Your files never leave your device — nothing is uploaded to a server.
True Alpha Channel
Exports preserve a real straight-alpha transparency channel (PNG / WebP / AVIF), not a baked-on background.
Free Forever
No account, no watermark, no credits. Open the tool and use it.
Works Offline
After the model downloads once it is cached, so the tool keeps working with no connection.
FAQ
Does it need a model?
No — it’s a pure colour heuristic that runs instantly.
Is it free to use?
Yes — AI Red-Eye Removal is completely free. No account, no watermark, no credits, and no usage limits.
Do my files or prompts ever leave my device?

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.
Where can I see a step-by-step guide?
Yes — there is a full walkthrough at /how-it-works/ai-red-eye.
