Free, private AI image & video upscaler

ScaleX upscales any image or video using AI, right inside your browser. It is 100% free and 100% private: every frame is processed locally on your own device, so nothing is ever uploaded to a server. There is no registration, no sign-up, and no upscale limits — enhance as many photos and clips as you like, at up to 4× resolution.
