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

How big an area can it fill?

Best on small-to-medium regions where surrounding texture can be sampled; very large fills are harder.

How do I mark the area?

Select the region to remove; the fill samples nearby content to reconstruct it.

Is it free to use?

Yes — AI Inpaint 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.

Where can I see a step-by-step guide?

Yes — there is a full walkthrough at /how-it-works/ai-inpaint.
