A screen recorder captures your display, window, or browser tab as a video — without installing any software. This tool uses your browser's built-in Screen Capture API to record and saves the result as a WebM file you can download, share, or edit in any video software.

How to Use the Screen Recorder
This browser-based screen recorder uses the W3C Screen Capture API to record your screen without any software installation. Here's how to capture your screen in seconds.
Step 1: Choose Your Audio Options
Before recording, decide whether to include audio. Toggle Include System Audio to capture sounds playing on your computer — music, notifications, or video audio. Toggle Include Microphone to record your voice. You can enable both for a full screen recording with narration. System audio capture works best in Chrome and Edge.
Step 2: Start the Recording
Click the Start Recording button. Your browser will show a native picker dialog where you select what to share — your entire screen, a specific application window, or just a browser tab. Choose your source and click Share. The recording starts immediately and a timer appears showing elapsed time.
Step 3: Pause or Stop
Use the Pause button to temporarily halt recording without ending the session — useful if you need to check notes or prepare. Click Resume to continue. When your recording is complete, click the red Stop Recording button.
Step 4: Preview and Download
After stopping, your recording appears in the preview player. Review it to make sure everything looks right. When satisfied, click Download Recording to save the WebM file to your device. The file size is shown so you know what to expect before downloading.
Converting WebM to MP4
The downloaded file is in WebM format, which is supported by all modern browsers and VLC. If you need MP4 for social media or specific platforms, convert it using a free tool like HandBrake or Cloudconvert. WebM provides excellent quality at small file sizes, making it ideal for sharing recordings quickly.
FAQ
Is this screen recorder really free?
Yes, completely free with no limits. There are no watermarks on your recordings, no time limits, and no signup required. All recording happens directly in your browser using the built-in Screen Capture API.
Is my recording data private?
Absolutely. Your screen recording never leaves your device. All processing happens entirely in your browser. The recorded video is stored temporarily in browser memory and is never uploaded to any server. You control when to download or discard it.
What format is the recorded video?
Recordings are saved as WebM format, which is widely supported by modern browsers, video players (VLC), and video editing software. WebM provides excellent quality at small file sizes. For MP4 conversion, use a desktop tool like HandBrake.
Which browsers support screen recording?
Chrome and Edge offer full support including system audio capture. Firefox supports screen recording but may not capture system audio. Safari has limited support — screen recording may not work at all. Chrome or Edge are recommended for the best experience.
Can I record just one window or tab?
Yes. When you click Start Recording, your browser shows a picker where you can choose to record your entire screen, a specific application window, or just a browser tab. The selection is made in the browser's native dialog, not this tool.
Can I record with audio?
Yes. You can enable system audio (what your computer plays) and/or microphone audio. System audio capture works best in Chrome and Edge. If system audio isn't available, microphone audio still works in all supported browsers.
Is there a recording time limit?
There is no hard time limit imposed by this tool. Recording continues until you click Stop. Very long recordings will use more RAM since the video data is stored in browser memory. For recordings over 30 minutes, a dedicated screen recording app may be more reliable.
