Record your screen and computer sound, right in your browser

RecordOnWeb records what you hear on your computer, your mic, or your screen. It runs in Chrome or Edge on Windows, Mac, ChromeOS, and Linux. There’s nothing to install and no audio drivers like BlackHole, Stereo Mix, or VB-Cable. Your recordings stay on your computer.

How it works

  1. Pick Sound or Screen, then choose what to record.
  2. Press Record. In Chrome’s share window, pick a screen and click Share.
  3. Press Stop. Trim or crop if you like, then save as M4A or MP4.

FAQ

How do I record my computer’s audio without installing anything?

Choose Sound, then Computer sound, and press Record. Chrome asks what to share: click any screen, keep “Also share system audio” on, and click Share. Only the sound is saved.

How do I screen record with sound?

Choose Screen, pick Entire screen, One window, or Browser tab, and set Sound to Computer sound, Mic, or Both. Press Record, pick what to share, and click Share.

Do I need BlackHole, Stereo Mix, or VB-Cable?

No. The browser captures your computer’s sound directly, so you can keep using your usual speakers or headphones.

Is it free? Are my recordings uploaded?

It’s free. Recording happens in your browser, and recordings are saved straight to your computer. They’re never uploaded.

Do you collect any data?

Your recordings never leave your computer. To improve the site, we use Microsoft Clarity to see how the page is used (clicks and scrolling, with file and device names hidden), and Google AdSense to show ads. See the privacy policy for details.

Which browsers and systems work?

Chrome or Edge on Windows, macOS, ChromeOS, and Linux. On a Mac, recording computer sound needs macOS 14.2 or later. On Linux, computer sound may not be available, but tab sound works. Safari and Firefox can’t record computer sound.

What file formats do I get?

Sound is saved as M4A (AAC) and screen recordings as MP4 (H.264 and AAC), which play in most apps. If your browser can’t make MP4, you get WebM.

Can I trim or crop a recording?

Yes. When you stop, a trim window opens. Drag the orange handles to cut the start or end, or use Crop to keep part of the screen. Hold a handle still to zoom in for precise cuts.

Why does Chrome ask to share my screen when I only want audio?

Browsers only allow computer sound through screen sharing, for your privacy. In Sound mode, the picture is ignored and only the sound is saved.

Get ready

Computer sound: just two clicks

When you press Record, Chrome asks Choose what to share. Entire Screen and Also share system audio are already set for you.

  1. Click any screen. They all record the same sound.
  2. Click Share. Recording starts.

Only sound is saved, not your screen. You share once, until you click Stop sharing.

Trouble?
  • Is Also share system audio off? Turn it on, then click Share.
  • Your Mac asks “Google Chrome” Would Like Access To Record Your System Audio? Click Allow.
  • Chrome asks you to allow screen recording? Open System Settings → Privacy & Security → Screen & System Audio Recording, turn on Google Chrome, then quit (⌘Q) and reopen Chrome.
  • No audio switch, or no sound? On the same page, turn on Google Chrome under System Audio Recording Only, then reopen Chrome. You need macOS 14.2 or later.
  • Chrome on Linux may not offer system audio. Share a browser tab to record its sound instead.

Screen: just two clicks

When you press Record, Chrome opens on the Entire Screen tab.

  1. Click the screen you want.
  2. Click Share. Recording starts.

While recording, Chrome shows “… is sharing your screen.” Click Hide to hide it, or Stop sharing to finish and save.

Trouble?
  • No computer sound? Make sure the audio switch is on before you click Share.
  • Chrome asks you to allow screen recording? Open System Settings → Privacy & Security → Screen & System Audio Recording, turn on Google Chrome, then quit (⌘Q) and reopen Chrome.
  • Still no computer sound? On the same page, also turn on Google Chrome under System Audio Recording Only.

Mic: click Allow

When you press Record, Chrome asks to Use your microphone. Click Allow on every visit (or Allow while visiting the site).

Wearing Bluetooth earbuds? Choose your computer’s built-in mic. Earbud mics switch to call mode and sound worse.
