Free local 2x video previews and MP4 export for short compatible clips.
Try a fixed 2x upscale of a short compatible MP4/H.264 clip, compare before and after, and export an MP4 locally. VideoUpscaler.dev uses WebGPU and WebCodecs to run an Anime4K CNN in a supported desktop Chromium browser, without a product account or desktop installation. The source video stays off cloud processing servers. Browser support, GPU capability, encoding, memory and clip length affect compatibility, speed and stability.
