ALTools
Screen Recorder
Record your screen in the browser with optional system audio and microphone. Download WebM instantly — nothing uploaded.
How to use this tool — step-by-step guideHow Screen Recording Works
Capture your screen, a browser window, or a single tab directly in the browser. Optionally include system audio and your microphone. ALTools records locally—nothing is uploaded and no account is needed.
Choose what to share when the browser prompts you, then start recording. The tool captures video (and audio if enabled) in real time. When you stop, download a WebM file; use the Video to MP4 tool if you need a widely compatible MP4.
Great for software demos, bug reports, quick tutorials, meeting snippets, or capturing gameplay and presentations without installing desktop software.
Recording stays on your device, so sensitive screens and audio never pass through a server. You control when recording starts and stops, and you can re-record until the take is right.
You get a WebM download ready to play in modern browsers or convert. Pair with MP4 conversion when you need to share the file on phones, editors, or platforms that prefer H.264.

No. Recording happens entirely in your browser. The video file is saved directly to your device.
Can I record system audio?
In Chrome and Edge, check "Share system audio" when picking a screen. Safari and Firefox may not support tab/system audio.
What format is the download?
Most browsers export WebM (VP9/VP8). Use our Video to MP4 tool if you need MP4.
