Free Online Breathing Exercise
A free, interactive breathing tool you can use right now — no app, no sign-up.
Free · No sign-up · Runs in your browser · Nothing to install · Silent, visual only
This is a free online breathing exercise — no sign-up, no ads, nothing to install, all of it running in your browser — where you press Begin and follow an animated orb through four rounds of box breathing, with each phase named and counted down on screen, Pause and Reset if you need them, and nothing saved when you close the tab. The rhythm is an even 4-4-4-4: in for four, hold for four, out for four, hold for four. The orb grows and shrinks so the counting is not your job, and it works the same on a phone, a tablet, or a computer.
How to Practice
- 1
Begin. Press begin and get comfortable, sitting or lying down.
- 2
Inhale. Breathe in through your nose for 4 seconds as the orb expands.
- 3
Hold. Hold gently for 4 seconds while the orb pauses.
- 4
Exhale. Breathe out for 4 seconds as the orb shrinks, then continue the rhythm.
Why Use a Guided Breathing Tool
The hardest part of breathing exercises is keeping the pace while also trying to relax. A guided online tool removes that effort: the animation expands as you inhale and contracts as you exhale, so you can close your mind to counting and simply follow along. Visual pacing has been shown to make slow breathing easier to sustain and more effective at calming the nervous system than counting alone.
Slow, paced breathing at around six breaths per minute activates the parasympathetic nervous system — the body’s natural brake — lowering heart rate and easing tension. Because the tool runs entirely in your browser, there is nothing to install and nothing tracked; you get an instant, private moment of calm whenever you need one.
How to Use This Tool
Press the begin button and follow the orb: breathe in as it grows, hold as it pauses, and breathe out as it shrinks. The phase label and countdown tell you exactly what to do at each moment, so there is nothing to memorize.
The default is box breathing, but you can explore other rhythms from the links below — the relaxing 4-7-8 pattern for sleep, or smooth 5-5 coherence breathing for everyday balance. Use whichever feels best for your situation.
Tips for Best Results
Find a comfortable position, sitting or lying down, and breathe into your belly rather than your chest. Keep the breath smooth and unforced, and let the exhale be slow and complete.
For the clearest experience, give the tool your full attention for a few rounds rather than multitasking. A minute or two is enough to feel a difference; a few rounds more deepens the effect. Practice regularly and the calm becomes easier to reach each time.
Link parameters
The round count travels in the address bar, so a link can open the exercise at the length you want. The page starts on four rounds unless the link says otherwise.
| Parameter | Values | Example |
|---|---|---|
| rounds | 1 to 20 rounds | /breathing-exercise-online/?rounds=6 |
/breathing-exercise-online/?rounds=6 runs six rounds rather than four, about a minute and a half.
/breathing-exercise-online/?rounds=12 is a longer sit of a little over three minutes.
Frequently Asked Questions
Is this breathing exercise free to use online? +
Yes. It is completely free, with no sign-up, no download, and no ads. Everything runs in your browser, so there is nothing to install on a phone, tablet or computer. Press Begin and the orb paces four rounds of box breathing; nothing is saved and nothing is sent anywhere.
Do I need to install an app? +
No. The tool runs entirely in your web browser on any device — phone, tablet, or computer. There is nothing to install and nothing to create an account for.
How does an online breathing exercise work? +
An animated orb expands and contracts to pace your breath, while on-screen labels and a countdown tell you when to inhale, hold, and exhale. You follow the visual instead of counting, which makes slow breathing easier and more relaxing.
Which breathing pattern should I choose? +
Box breathing (4-4-4-4) is a great all-purpose default for calm and focus. For sleep, try 4-7-8 breathing; for everyday balance, try 5-5 coherence breathing. Links to each are below.
Is my data private? +
