Pixel Clock Online — Free Retro LED Digital Clock

A Real Pixel-Grid Clock, Glowing

Every digit is drawn dot by dot on an actual 5x7 grid — the same way a real LED scoreboard or calculator display works, not a font dressed up to look retro. Runs as a page you can leave open instead of software you install.

Where People Put It

Gaming and streaming setups

The dot-matrix digits read like a real arcade scoreboard or CRT terminal rather than a plain sans-serif readout — pin it to a corner of your stream or second monitor.

A terminal-style ambient display

If your desktop already leans dark-mode-and-monospace, this fits the same visual language instead of looking like a stock OS clock widget.

Bedside night display

Pixel Amber and Pixel Red glow without being a harsh white light source — dim enough to read across a dark room without lighting up the whole space.

Retro gaming corner

Sits well next to a CRT monitor, arcade cabinet, or retro console shelf — the dot-matrix glow matches 80s/90s gaming hardware far better than a modern flat-panel clock widget would.

How to Use

No settings menu to dig through — four steps and it's running.

Open in any browser

There's no loading screen to wait through — every dot is lit as soon as the page opens, and it holds up whether you're using a phone, a laptop, or a second screen.

Pick your glow color

Settings holds all eight glow colors behind one tap, and your pick carries over the next time you're back.

Tweak the display

Format, seconds, and the date each get their own switch in Settings — flip any one of them without touching the glow or the others.

Go fullscreen

The fullscreen button strips the browser away, leaving a standalone LED marquee; pair it with Keep Screen On if you don't want it dimming while you're away.

Features

The short list of what's under the hood.

12 / 24-hour format

AM/PM or 24-hour, rendered dot-by-dot in the same 5x7 grid as the rest of the display — no separate font swap needed.

8 dot-matrix colors

Green, Amber, Red, Blue, Purple, White, Cyan, and Pink — eight glow colors, all drawn on the same real dot-matrix grid.

Fullscreen mode

Strip the browser tab away entirely and it reads like a real scoreboard or arcade marquee, not a webpage.

Keep screen on

Backed by the Wake Lock API, so the display keeps glowing instead of your laptop deciding to sleep on you.

Works everywhere

Open it on a phone, a tablet, or a spare monitor — the dot grid scales cleanly at any size.

Runs in your browser

Nothing calls home to a server — everything renders client-side, and your settings live in this browser, not an account.

FAQ

What people usually want to know before switching to this one.

Is this actually a pixel/dot-matrix display, or just a retro font?

It's a real dot-matrix rendering — each digit is drawn dot by dot on a 5x7 grid, the same way a physical LED scoreboard or calculator display works. It's not a font styled to look blocky; the grid is genuinely built that way.

Can I change the glow color?

Yes — eight colors are available in Settings, including Green, Amber, Red, Blue, Purple, White, Cyan, and Pink, each with its own glow intensity.

Is this good as a streaming overlay?

Yes. Because the background is transparent-black and the glow reads clearly at a distance, it holds up well as a small on-screen element in OBS rather than needing to fill the whole frame.

Does the glow strain your eyes at night?

The amber and red variants are dimmer and warmer than the green — most people use those two for a dark room rather than the brighter green.

Will it keep my screen from sleeping while it's on?

Only if you turn on Keep Screen On in Settings — it's off by default so the pixel clock doesn't override your device's normal sleep behavior unless you ask it to.

Does it work well next to other RGB or retro gaming gear?

Yes — Purple, Cyan, and Pink pair naturally with RGB keyboards and case lighting, while Green and Amber lean toward a classic monochrome-terminal or arcade-cabinet look.
