What Free AI Video Upscaler is
Free AI Video Upscaler is a free browser-based tool for enlarging videos and images with AI. Video processing runs on the user's device through WebGPU, with WebGL as a fallback; the site says its approach is based on WebSR and ports open-source algorithms such as Anime4K and RealESRGAN to WebGPU. Video output can reach 4K, while image output can typically reach 8K depending on the device. Enhancement modes include Fast, Balanced, Quality, Ultra, Anime4K and RealESRGAN. It handles MP4 and WebM, along with other formats the browser can play natively. The FAQ says there are no video-length or file-size limits, although large files may process slowly depending on the device. Multiple videos cannot be processed at once, but can be handled in sequence. Supported browsers listed are Chrome 94+, Edge 94+, Opera 80+, Safari 16+ and Firefox 130+, and WebCodecs API is required. Video content is processed locally and not uploaded to the maker's servers; anonymous usage analytics and technical error logs are collected.
