Description
FreeUpscaler upscales video and images entirely inside your browser. The file isdecoded frame by frame with WebCodecs, enlarged on your own GPU through WebGPU,
and re-encoded locally — nothing is ever uploaded to a server. You can verify
that yourself: open the page, disconnect from the internet, and it still works.
Because the work runs on your hardware instead of a rented cloud GPU, there is
nothing to meter. No account, no credit counter, no watermark, no export cap and
no file-size limit. Video keeps its audio track, copied across without being
re-encoded, so it stays in sync and loses nothing.
Every capability claim on the site is measured rather than asserted. The instant
shader methods produce a 1080p frame in about 6 ms on a laptop GPU — roughly
seven times faster than the footage plays; the neural methods trade that for
quality at about 345 ms a frame. The site publishes which method loses, on what
material, and by how much. Needs desktop Chrome or Edge for WebGPU and WebCodecs.
