Play piano online — free, instant, no download
A full two-octave piano, ready to play the second this page loads. Click a key, tap it on a touchscreen, or use your computer keyboard — no install, no account, no waiting.
Getting started in a few seconds
- Click or tap any key above, or press a letter on your computer keyboard — A S D F G H J K L for white keys, W E T Y U for the black keys between them.
- Hold several keys together for a chord — each note plays independently, so they don't cut each other off.
- Use the octave buttons to reach higher or lower notes than the two octaves shown by default.
- Turn sustain on if you want notes to keep ringing after you let go, closer to a piano's sustain pedal.

Why play piano online instead of an app
A browser-based piano skips the install step entirely — there is nothing to download, no app-store account, and no storage taken up on your device. It works identically whether you land here from a phone, a shared computer, or a library terminal, and closing the tab is the entire "uninstall." The tradeoff is real and stated plainly in the FAQ and on the about page: it is an oscillator-based synth, not a sampled piano, so it will not fool anyone into thinking it is a recording of a real instrument.
Frequently asked questions
Do I need to install anything to play piano online here?
No. This piano runs entirely as a web page using the Web Audio API already built into your browser — there is nothing to download, no plugin, and no account to create. It works the same way on a laptop, a phone, or a tablet.
Can I play piano online with just my mouse, or do I need a keyboard?
Either works. Click or tap any key directly with a mouse or touchscreen, or use your computer keyboard for faster playing — the home row plays white keys and the row above fills in the black keys, with the mapped letter shown right on each on-screen key.
Is this free to play piano online, with no hidden limits?
Yes, currently free with no note limit, no time limit, and no account required. Everything runs locally in your browser rather than through a paid service.
