What does auto-enhance do?

It analyzes your photo (exposure, color cast, noise) and plans a correction: levels, white balance, denoise and sharpening — applied in one click, with undo history.

How does the AI upscaler work?

Real-ESRGAN super-resolution runs in your browser via WebGPU (with a WASM fallback). The model downloads once (~size shown before download) and is cached for offline use.

Are my photos private?

Completely. Enhancement and upscaling run on your own hardware — photos never leave your device.

Can I process many photos at once?

Yes — batch mode queues photos with per-photo progress and downloads everything as a ZIP.
