## About

VideoUpscaler.dev is a free browser-based utility for creators who want to preview and enlarge a short MP4/H.264 video by 2x without uploading their source footage. It runs an Anime4K CNN model locally through WebGPU and WebCodecs on compatible desktop Chromium browsers. Processing speed and availability depend on local hardware, browser support, clip length, and source resolution. The tool is designed for short clips, not cloud rendering, long-video batch processing, frame interpolation, or guaranteed 4K output.

## Pricing

Free to use; no product account required.
