Paste your Binary into the box above and the Gray code appears instantly below — there is no button to press and nothing to upload.

Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android with nothing to install, and works offline once loaded. The result can be copied or downloaded on any device.
