The No Signal is a free, full-screen browser tool — Retro colour-bar static. It runs entirely in your browser, needs no install or sign-up, and renders locally so nothing you see is uploaded anywhere.

How to use the No Signal

1. Click Launch fullscreen below.
2. Use the on-screen controls (they fade in when you move your mouse or tap) to adjust color, speed or timing.
3. Press F or double-click the screen for true browser fullscreen, and Esc any time to exit.

Why use no signal?

Whether you’re on a call, recording, streaming, working, or just need a quick full-screen effect, the No Signal is ready in one click — no downloads, no watermark, and it works on any device with a modern browser.
