What is a Screen Recorder?
A Screen Recorder captures your screen, a browser tab, or your webcam directly through your browser, without requiring separate software installation.
Our free Screen Recorder processes everything locally using your browser's built-in Screen Capture API, letting you download a finished MP4 in seconds.
Browser-based screen recording works through the Screen Capture API, a standard built directly into modern browsers that lets a webpage request permission to record your screen, a specific tab, or your webcam, without requiring you to install any separate desktop software at all. This makes the whole process meaningfully more convenient than a traditional recording application, but it also comes with real, browser-specific limitations worth knowing upfront.
Our Screen Recorder captures your screen, a single browser tab, or your webcam directly through this built-in API, then lets you download the finished recording as an MP4 file once you're done. A properly built browser-based recorder like this one processes everything locally using this API, meaning your recording stays on your device throughout the process and is never uploaded to any external server during recording itself.
There's a genuine, specific limitation worth understanding clearly: browser support for capturing system audio, meaning sound from other applications playing on your computer, varies significantly. Chrome and Edge can capture tab audio specifically, but neither Firefox nor Safari currently support capturing full system audio output through the browser's recording API at all, regardless of settings. Screen recording also doesn't work reliably on most mobile browsers, since they generally don't support the same screen capture APIs desktop browsers rely on, meaning this kind of tool is primarily built for and limited to desktop use. Since the recording is held in your browser's memory during the process, closing the tab before downloading will typically lose the unsaved recording entirely, so downloading your video before navigating away is worth doing every time.
