About

          Compare a short video with a fixed 2x upscaled preview before exporting the result. VideoUpscaler.dev is a free browser utility for compatible MP4/H.264 clips. It runs an Anime4K CNN workflow on-device through WebGPU and WebCodecs in supported desktop Chromium browsers, with before-and-after comparison and local MP4 export. The current workflow needs no product account or desktop installation, and source footage is not uploaded for cloud video processing. Browser support, GPU capability, source resolution, memory and clip length affect compatibility, speed and stability.
