About UniFab

It operates entirely in a web browser with no installation or dedicated GPU required, using enterprise cloud GPUs via the FabCloud platform. Users can upload videos from any device, process them frame-by-frame for natural-looking results, and queue multiple files for batch enhancement. The service is free to start with FabCloud credits (no credit card needed) and offers a desktop application with additional advanced AI features like upscaling up to 16K, SDR to HDR conversion, audio upmixing, and more.
