Record a screen, window or browser tab with optional microphone and webcam overlay. Pause, preview and download locally in a supported desktop browser.
Choose a capture surface and sources explicitly, then review the saved recording.
Paused time is excluded from the recording timer. Shared audio is included only when the browser supplies an audio track for the chosen surface.
Download before closing the tab. Testing with a short clip first helps confirm microphone and shared audio permissions.
Record your screen by choosing optional microphone and webcam sources, pressing Start recording, and selecting the screen, window or browser tab in the browser’s sharing dialog. Pause and resume as needed, then stop to preview and download the recording. Captured video and audio stay in browser memory rather than being uploaded.
The browser controls what can be captured and asks for permission on every new recording session. Shared tab or system audio is available only when the browser and operating system support it for the chosen surface. Requesting shared audio does not guarantee that a track is supplied. The tool reports when none was supplied, while microphone recording requires its own device permission.
A webcam overlay is composited into a local canvas with a selectable corner and a maximum 1080p output for that mode. Without an overlay, the recorder uses the browser-provided screen video track. The recording format is selected from supported WebM or MP4 options. A 250-megabyte buffer limit prevents unlimited memory growth; save the result before starting another session or closing the tab.
Enable Microphone for narration, Webcam overlay for a camera inset, and shared audio if needed. Pick the camera corner before recording because these settings stay fixed during the session.
Press Start recording and use the browser dialog to choose a tab, window or screen. For tab sound, enable the browser’s audio-sharing option when offered.
Use the live preview and timer to follow recording. Pause excludes the pause interval from the elapsed recording time. Press Stop recording or the browser’s Stop sharing control to finish.
Play the resulting video, check sound and framing, then download the offered WebM or MP4 file. Your recording is not saved automatically and disappears when the session is cleared.
Uses explicit screen-sharing permission rather than hidden recording or remote access.
Adds a corner webcam inset and mixes available shared audio with microphone input.
Provides pause, resume, a captured-byte readout, playback and a downloadable result, with an explicit memory limit.
Capture a browser tab and microphone narration, optionally adding a webcam introduction or explanation in a corner.
Show the steps leading to a bug in a selected application window, then save a short video for a support ticket.
Record slides with narration and inspect the saved result before sharing. Use a screen without unrelated notifications or private information.
Open the tool in a supported desktop browser over HTTPS, press Start recording, and choose a screen, window or tab in the sharing dialog. Stop and download the resulting video.
Support depends on browser, operating system and capture surface. Choose a browser tab and enable its audio-sharing checkbox when available. The tool reports when the shared stream contains no audio.
Yes. Enable either source before starting and grant device permission. Camera composition uses a local canvas and can slow down if the recorder tab is hidden.
Many mobile browsers do not expose browser screen capture. The tool checks availability and recommends a supported desktop browser when capture is unavailable.
The recorder selects an available WebM codec or MP4 fallback according to browser support. The download extension matches the actual selected format.
It stays in this tab’s memory until you download or clear it. The tool stops at a 250-megabyte buffer limit. Closing the tab or starting another recording discards the in-memory copy.
Your browser asks which surface to share. Webcam composition is capped at 1080p and may slow down when this tab is hidden. Shared audio depends on browser, operating system and chosen surface.

Maximum recording buffer: 250 MB. Desktop browsers work best. Some browsers produce recordings without seekable duration metadata; playback and download still work. Check the saved video and audio before relying on it.
