BlogRecord Your Screen Online in Chrome, No Install
Learn how to record your screen online in Chrome without installing software. Pick a tab, window or full screen, add mic and system audio, and save a seekable video.
You need to record a bug, a tutorial or a meeting demo, and installing a screen recorder for a one-off job feels like overkill. Good news: Chrome, Edge and other modern browsers can record your screen online with no install, because recording is built into the browser itself.
How browser screen recording works
Two standard web APIs do the work. getDisplayMedia asks you which screen, window or tab to share, and MediaRecorder encodes that stream into a video file. Because both run inside your browser, Online Screen Recorder does the recording on your own device: you get a preview and a file to download without creating an account.
Step-by-step: record your screen
- Open Online Screen Recorder.
- Open Recording settings and choose Resolution, Frame rate and Format (details below).
- Tick Record system audio and/or Record microphone if you need sound.
- Click the big red record button. Your browser shows a picker: entire screen, a window or a browser tab. Choose one and confirm.
- Use Pause and Resume as needed. Click Stop, or use the browser's own "Stop sharing" bar, to finish.
- Preview the result, then click Download. Use New Recording to start over.
Tip: for a clean result, close notification-heavy apps first. Anything visible in the shared area gets recorded.
Which settings should you pick?
| Setting | Options | Good default |
|---|---|---|
| Resolution | Auto (follow source), 1080p, 720p, 480p | Auto, or 720p for smaller files |
| Frame rate | 15, 30, 60 fps | 30 fps; 60 only for games or smooth animation |
| Format | WebM, MP4 | WebM; MP4 is offered only if your browser supports it |
Lower resolution and frame rate mean smaller files, which matters for long recordings you plan to share.
Recording sound: the part that trips people up
Audio is where most "my recording has no sound" complaints come from.
- System audio: tick Record system audio. Browser support varies. Chrome usually offers a "share tab audio" checkbox in its picker when you choose a tab; you must tick it there too. Capturing whole-system audio depends on your OS and browser.
- Microphone: tick Record microphone and allow the permission prompt. The tool mixes mic and system audio into one track. If mic access is denied, it still records the screen without your voice.
- If your recording is silent, redo it and check both the tool's checkbox and the checkbox inside the browser picker.
Tab, window or full screen?
| Choice | Best for | Note |
|---|---|---|
| Browser tab | Web demos, tab audio | Most reliable for capturing page sound |
| Window | One app, e.g. a document | Other windows stay out of the video |
| Entire screen | Multi-app workflows | Records everything, including notifications |
Common problems and fixes
| Problem | Likely cause | Fix |
|---|---|---|
| Permission denied error | You dismissed or blocked the picker | Click record again and allow screen sharing |
| No sound | Audio checkbox not ticked in the tool or the picker | Enable both, or pick a tab |
| Can't drag the progress bar | Missing duration metadata in raw WebM | The tool writes it in on export, so download from here rather than using a raw browser recording |
| MP4 is greyed out | Browser can't record MP4 | Use WebM, which plays in most modern players |
| Recording stops itself | You clicked "Stop sharing" | That ends the recording by design |
Background: why WebM files often can't seek
Browsers stream recordings chunk by chunk, so a WebM file is usually finished without a total duration in its header. Some players then show an unknown length and won't let you jump around. Online Screen Recorder measures the exact recording time (pauses excluded) and writes the duration in after you stop, so the exported WebM supports dragging the progress bar. MP4 already carries this information natively.
Need a screenshot instead?
If a still image is enough, Online Screenshot captures the screen and lets you annotate it. To record your webcam rather than your screen, use Online Video Recorder.
FAQ
Is it really free with no software to install?
Yes. Everything runs in your browser tab, and there is nothing to download before you record.
Can I record with my voice narration?
Yes. Tick Record microphone. It is mixed with system audio if you enabled that too.
Why is there no MP4 option?
MP4 recording depends on browser support. If it is unavailable, choose WebM, which the tool exports with a working progress bar.
Can I pause the recording?
Yes. Use Pause and Resume; the paused time is not counted in the final duration.
Does it work on a phone?
Screen capture through getDisplayMedia is mainly a desktop-browser feature, so use Chrome or Edge on a computer for reliable results.
Summary
To record your screen online, open Online Screen Recorder, pick a tab, window or screen, decide on audio, then stop and download. Choose a tab when you need page sound, keep 30 fps for most jobs, and check both audio checkboxes if the result is silent. For a full walkthrough of the tool, see the screen recorder guide.
