Frequently asked questions

Is this AI upscaling?

No - it uses high-quality multi-step resampling and sharpening on your device. It enlarges cleanly but can't invent detail that isn't in the original the way a server-side AI model can.

Are my images uploaded?

No. Everything is processed locally in your browser - the image never leaves your device.

Which format should I download?

PNG for graphics and screenshots (lossless), JPG or WebP for photos to keep the file smaller.
