# Online screen recorder: record screen, camera, and audio

Record your screen, camera, and audio in your browser with no watermark.

Records a screen, window, or browser tab with system sound, microphone, and an optional camera overlay in the browser, then trims, cleans up, or downloads as MP4, WebM, MP3, or WAV. It runs in the person's browser, so it's free with no limit, and there's no API call for it. A recording opens in the editor when it stops, where the person can trim it, download it, or run Audo's tools on it.

## How it works

1. Choose whether to include your camera, microphone, or computer sound, then press Record.
2. Pick a browser tab, an application window, or your full display in the sharing prompt.
3. Stop when finished, trim dead air on the timeline, and save your video or audio.

## Browser screen capture without extra software

Audo's free online screen recorder captures your display, application window, or browser tab with webcam video, microphone narration, and system audio directly in the browser, with no install, no watermark, and no sign-up. Clips save locally as MP4 or WebM video, or as MP3 or WAV audio, and stay on your machine unless you run an Audo tool.

Most desktop recorders ask you to download heavy apps or configure virtual audio routing just to capture a quick demo. Browser capture uses your operating system's native screen picker instead: tick the audio box when picking a tab or screen to record a screen recorder with audio from slides, web apps, or video calls.

Once you stop, your capture lands straight in the built-in editor with the video preview synced above the audio waveform. Drag the handles to trim the setup at the beginning and end, cut out stumbles in the middle, or clean up fan hum and hollow laptop narration before downloading.
