VideoUpscaler.dev

VideoUpscaler.dev helps independent creators improve compatible short videos without sending their original footage to a cloud service. It is a currently free, browser-based video upscaler designed for people who want to test a clear 2x result before editing, sharing, or publishing. Choose a short MP4/H.264 clip, inspect the local preview, and export the processed output in a compatible desktop Chromium browser. The tool uses WebGPU for accelerated on-device inference, WebCodecs for supported browser media handling, and an Anime4K convolutional neural network for model-based upscaling. Processing stays on the user’s own device; the current workflow requires no product account, desktop installation, or source-video upload. It is a practical fit for animation clips, short social videos, older recordings, product demos, and privacy-sensitive creator footage. Clear limits matter: the verified workflow is fixed at 2x and intended for supported short clips. Performance, stability, and maximum practical length depend on browser compatibility, GPU capabilities, source resolution, and the original video. Upscaling cannot recreate detail that was never in the source.
