About VideoUpscaler.dev
VideoUpscaler.dev is a free privacy-first AI video upscaler for short MP4/H.264 clips. A compatible desktop Chromium browser runs an Anime4K CNN model locally with WebGPU and WebCodecs. Creators can preview the result and export a 2x upscale without uploading footage or creating an account. Speed varies with the user's hardware and clip size.
