About LED Scroller

What LED Scroller is

LED Scroller is a free online tool that turns your phone, tablet or computer screen into a scrolling LED sign. Type a message, pick your colours and it runs across the screen like a real dot-matrix display. People use it to hold up a sign at a concert, greet someone at the airport, cheer at a match, light up a party, send a message from a car window or put a quick notice in a shop window. It works for anyone who needs a big, bright, readable message right now, without buying hardware.

Who makes it

LED Scroller is made by CODELIO, a small independent app studio based in France. We build simple, useful apps and websites. We also publish the free LED Scrolling Board app on Google Play, the Android version of this tool, rated 5.0 from 171 reviews. There is no iOS app: on an iPhone or iPad, this website is the way to use it.

How the tool works

The website draws a real dot-matrix grid on an HTML canvas, directly in your browser. There is no signup and nothing to install, and it is free. Your banner text stays on your device: it is not sent to our servers. You can set:

Any text, including emojis
Solid text colour or per-letter multicolour
Background colour of your choice
Font size and bold text
Glow and blink effects
Scrolling speed from 1 to 20 and a choice of direction
An animated LED border
Fullscreen with landscape mode on phones
Download as a PNG image or an animated GIF
