# recorder.video > Free online screen recorder for your screen, webcam and mic. Records in your browser with no upload, watermark or sign-up. Trim and download MP4, WebM or GIF. recorder.video captures the screen, webcam and microphone with the browser's own media APIs, then encodes MP4 or WebM on the device.

Click Screen, choose what to share, and tick “Share tab audio” or “Share system audio” in the browser’s picker. Keep the microphone on to add your voice. Tab audio works in Chromium browsers such as Chrome and Edge; system audio for an entire screen is available on Windows and ChromeOS. ### Why is there no sound in my screen recording? Usually the audio box in the share picker was not ticked, or a window was shared (browsers can’t capture audio from a single window). macOS does not let browsers capture system audio from the entire screen, so share a browser tab instead. Also check the microphone isn’t muted: the level meter on the mic button moves when it hears you. ### Is there a time limit? No. recorder.video doesn’t cap recording length. Recordings are saved in your browser’s storage, so the practical limit is the free disk space your browser allows this site, which you can check under Settings. ### Does recorder.video cost anything or stamp a logo on my video? No and no. Recording is free, and nothing is stamped on the MP4 you download: no logo and no watermark. ### Do I need to install anything or sign up? No. It runs in a modern browser with no extension, download or account. Your browser will ask permission to use the camera, microphone and screen. ### Does recorder.video upload my recording? No. Capture, previews, editing and downloads happen in your browser and recordings stay in your browser’s storage. There is no upload path in this tool. ### Does it work on Mac, Windows, Linux and Chromebook? Yes, in modern desktop browsers on macOS, Windows, Linux and ChromeOS. Chrome and Edge have the broadest support (tab audio, picture-in-picture controls); Firefox and Safari can record the screen, camera and microphone where their APIs allow. ### Can I use it on iPhone or Android? Mobile browsers don’t allow websites to capture the screen, so on phones and tablets you can record your camera and microphone only. Use your phone’s built-in screen recorder for the screen itself. ### Can I record just one window or browser tab? Yes. When you click Screen, the browser lets you choose an entire screen, a single window or a tab. Recording a tab is the easiest way to include that tab’s audio. ### What format are the downloads? MP4 when your browser can record it (recent Chrome, Edge and Safari), otherwise WebM. You can pick MP4 or WebM in Settings, download audio only, or make a short GIF of up to 20 seconds. ### Can I trim a recording afterwards? Yes. Select a scene, drag the yellow start and end handles on the timeline (or press I and O at the playhead), and the trim is applied when you download. The original recording is kept, so you can change the trim later. ### Can I change the layout after recording? Partly. The downloaded video keeps the layout you recorded with, but screen, camera and microphone are also saved as separate source tracks for each scene, so you can preview a different layout later or download the sources as a ZIP to rearrange in an editor. ### Can websites detect that I’m recording my screen? Websites and apps generally can’t tell that you are recording your screen with this tool. Your browser shows you its own indicator while a screen, tab, camera or microphone is being shared. Some copy-protected video players appear black in recordings. ### What happens if the browser crashes during a recording? Chunks are saved to IndexedDB while recording. On the next load, unfinished scenes are marked as recovered so you can review and download what was written before the crash.
