Nebula stores a tiny proxy of every image. The browser reconstructs full quality on the user's own GPU. Your bandwidth drops by 90%. Your users see no difference.

Everything runs locally in your browser. Nothing is uploaded.
How it works
- Your server stores a 5% proxy — a tiny, lossy version of the original.
- The browser downloads the proxy instead of the full file.
- WebGPU runs a Lanczos-3 resample + unsharp mask to restore detail.
- The user sees a sharp image. You paid for 1/20th of the bytes.
