HOW IT WORKS
01

Choose audio

Record system/tab audio only, or add your microphone for narration.

02

Pick what to share

Start recording and select a screen, window, or tab in the browser dialog.

03

Stop & download

Stop the capture, preview the result, and download the browser-supported video file.

Record your screen online — right now, no install

In a supported desktop browser, you can capture a full screen, window, or tab without installing an extension. The browser controls which sources and audio options it exposes. The finished WebM file is assembled locally, making the tool useful for quick bug reports, tutorials, product walkthroughs, and feedback clips.

Capture audio the right way

You can record system or tab audio, your microphone, or both mixed together. Two things to remember: choose your audio mode before you start, and tick “Share audio” in the browser’s share dialog so system sound is included. For narrated demos, the “System + microphone” option blends both into one track — it is worth a quick microphone test first to confirm your input level.

Private and local

The recording is assembled locally and downloaded to your device rather than uploaded by this tool. Long captures still depend on browser stability, available memory, storage, and operating-system capture behavior, so use a desktop recorder for important or extended sessions.

When you need more polish

This browser tool produces a raw local capture. ScreenBuddy for Mac and Windows adds editable auto-zoom, spotlight, lightbox, annotations, backgrounds, and local MP4 or GIF export after licensing. Use the browser tool for a quick clip and the desktop editor when the walkthrough needs a directed attention pass.

FAQ

Frequently Asked Questions

Is this browser screen recorder free and local?
Yes. It records with your browser's screen-capture API and builds the video file on your device without an account. Available capture sources, formats, and audio options depend on your browser and operating system.
Can I record system audio and my microphone?
Yes. Choose "System + microphone" before recording. To capture system or tab sound, also tick "Share audio" in the browser’s share dialog. The tool mixes both into a single track.
Where do my recordings go — are they uploaded?
Nowhere but your own device. The recording is assembled in your browser and downloaded directly to your computer. Nothing is uploaded to a server, which makes this safe for confidential or internal content.
What format is the recording?
The browser chooses a MediaRecorder format it supports, commonly WebM and sometimes MP4. The download button shows the resulting extension. If you need a GIF, use the MP4 to GIF tool; ScreenBuddy supports local MP4 and GIF export after licensing.
Why is there no audio in my recording?
Browser security requires you to explicitly enable "Share audio" (or "Share tab audio") in the screen-picker dialog. If that box is unticked, only video is captured. Re-record and make sure it is enabled.
Which browsers does the online screen recorder work in?
It requires a modern desktop browser that exposes both screen capture and MediaRecorder APIs. The browser and operating system decide which screens, windows, tabs, audio sources, and output formats are available. Mobile browser support is limited, so test the workflow before an important recording.
