Virtual Fireplace
A cozy, endlessly burning fire drawn live in your browser. Press Play crackling sound for the soft roar and snaps of a wood fire, choose a classic or colorful flame, set how strongly it burns, then go full screen on a TV, laptop or tablet. A sleep timer lets the fire burn down on its own.

The fire has burned down.
How to use the Virtual Fireplace
- Watch it burn: the fire starts automatically with a medium, classic wood flame.
- Add sound: press Play crackling sound and set the volume. Browsers only allow audio after you click, so it starts muted.
- Style it: pick a flame color and scene, and move the Intensity slider to make the fire calmer or livelier.
- Go full screen: press Full screen (or double-click the fire). Press Esc to leave.
- Fall asleep to it: choose a sleep timer. During the last minute the fire burns down and the sound fades to silence.
Ways to use a virtual fireplace
| Setting | Suggested options | Why |
|---|---|---|
| TV during a party or holiday dinner | Brick hearth, classic color, intensity 6-8, sound low | A lively fire reads well from across the room without drowning out conversation |
| Falling asleep | Classic or candle, intensity 3-4, sleep timer 30-60 min | A calm, slow flame and a soft roar that fades out on its own |
| Reading or studying | Stone hearth, intensity 4-5, pops and snaps on | Gentle background noise that masks distractions |
| Camping-themed evening or kids' story time | Campfire at night, sparks on | Starry sky and rising sparks set the mood for stories |
| Video call or stream background | Any scene, room glow off | Keeps the image steady without brightness pulsing |
How the fire is made
The flames are a particle system. Every frame, dozens of soft glowing particles are born along the logs, rise, drift toward the center like real flame tongues, change from a white-hot core through yellow and orange to deep red, and fade out. Drawing them with additive blending makes overlapping particles brighter, which is what gives the fire its glowing heart. Embers on the logs pulse independently, and sparks are thrown up at random, more often at higher intensity and when the audio plays a loud pop.
The sound is built from three layers: low-passed brown noise for the steady roar of burning gas, a faint high hiss, and thousands of tiny noise bursts with random pitch and loudness for the crackles of moisture and resin bursting in the wood. None of it is a recording, so there is no loop to notice.
Why real flames have different colors
- Yellow and orange come from tiny particles of soot glowing because they are hot. A wood fire is mostly this kind of light.
- Blue appears where gas burns cleanly with plenty of oxygen, like a gas stove, and comes from excited molecules rather than glowing soot.
- Green, purple and other colors in real fires come from metal salts (for example copper compounds burn green). These are for fireworks professionals only; enjoy them safely on screen.
Frequently asked questions
How do I put a virtual fireplace on my TV?
Open this page on a smart TV browser, or cast or mirror a laptop, phone or tablet browser tab to the TV, then press Full screen. Because the fire is drawn live instead of streamed as video, it uses almost no internet data once the page has loaded.
Is the crackling sound a recording?
No. The sound is synthesized in your browser with the Web Audio API: filtered noise makes the soft roar and hiss, and short random bursts of noise make the snaps and pops, so it never repeats like a looped recording. The amount of crackle follows the Intensity slider.
Why doesn't the sound start by itself?
Browsers block websites from playing audio until you interact with the page. Press Play crackling sound once and it will keep playing until you stop it, the sleep timer ends, or you close the tab.
Will my screen turn off while the fireplace is running?
In full screen mode the page asks the browser for a screen wake lock, which keeps the display on in Chrome, Edge, Safari 16.4+ and most Android browsers. If your browser does not support it, set your device's screen timeout longer or plug it in.
How does the sleep timer work?
Choose 15, 30, 45, 60, 90 or 120 minutes. The remaining time is shown under the controls. In the final minute the flames shrink to embers and the sound fades out smoothly, then the fire goes dark. Press Relight fire to start again.
Can I change the color of the flames?
Yes. Choose classic wood fire, warm candle glow, blue gas, green, purple or rainbow. Colored flames are just for fun: in real fireplaces such colors come from special chemicals, so never add anything to a real fire to copy them.
Does it use a lot of battery?
The animation uses your device's graphics a little like a simple game. Lowering the intensity reduces the number of flame particles and the work required. On laptops and phones, plugging in is best for long sessions.
