What is Free AI Video Upscaler?

Free AI Video Upscaler A browser‑based AI tool that enlarges video and image resolution using WebGPU and open‑source algorithms such as Anime4K and RealESRGAN. Users upload a file, and the browser processes each frame in real time, generating an upscaled output without server‑side storage or sign‑up.

The application supports common web‑friendly formats (MP4, WebM) and is optimized for animated and low‑resolution content. It provides a simple drag‑and‑drop interface, a side‑by‑side comparison view, and options for selecting output resolution (Small, Medium, Large).
