What Free AI Video Upscaler is
Free AI Video Upscaler is a free browser-based tool for enlarging videos and images using AI. Video processing runs locally on the device through WebGPU, with WebGL as a fallback, so video content is not uploaded to the maker's servers. Video output can reach 4K, while image output can typically reach 8K depending on the device. Users can choose Fast, Balanced, Quality, Ultra, Anime4K, or RealESRGAN enhancement modes. The tool accepts MP4 and WebM files, along with other video formats that the browser can play natively. Its FAQ says there are no video-length or file-size limits, although large files may take longer depending on the device. Multiple videos cannot be processed at the same time, but can be handled one after another. Supported browsers listed by the FAQ are Chrome 94+, Edge 94+, Opera 80+, Safari 16+, and Firefox 130+, with WebCodecs API required. The privacy policy says the service collects anonymous usage analytics and technical error logs, not personal information or video content.
