Are my images uploaded for AI processing?

No — all AI processing runs in your browser using WebAssembly. Files never leave your device.

How accurate is the AI processing?

AI tools use state-of-the-art WebAssembly models. Background removal and upscaling give excellent results for standard subjects. Complex backgrounds or very small subjects may need a second pass.

Does AI processing require an internet connection?

The AI models download once on first use (about 2–5MB). After that, processing runs entirely offline in your browser via WebAssembly.
