About Image Upscaler
Upscalers split into two families. Pure interpolation never changes content but never adds detail. Reconstruction adds texture — and pushed too far it turns a face into a different person and text into gibberish. Content Type sets a safe range for you.

Image handling and privacy
This is an AI tool: images you upload are sent to the configured inference service for processing, not handled locally in the browser. The active route is managed internally and is separate from the model developer. You can delete any generation from your history at any time.
