About the Screen Recorder
Record your screen straight from the browser — no extension, no install, no account, no watermark, and no upload: the recording is captured and saved entirely on your device. Choose a full screen, a single window or a single browser tab, optionally mix in your microphone and tab audio, and download the result the second you stop.
What people record
Quick how-tos: “click here, then here” explained in a 40-second recording beats ten screenshots and a page of text — the classic use for IT help, client handovers and team onboarding. Bug reports: a recording of the bug happening, with the console open, is the single most useful attachment you can give a developer. Demos and reviews: product walkthroughs, code reviews, homework explanations. Meetings and webinars: capture a tab playing a live session (check the host’s rules first).
Microphone, tab audio, or both
Tick microphone to narrate over the recording. Tick tab/system audio to capture the sound the computer is playing — note that browsers reliably capture audio when you share a tab; sharing a whole screen or window often comes without system sound (a browser limitation, not a bug). When both are on, the recorder mixes them into one soundtrack. A practical recipe for narrated demos: share the specific tab, enable both, and speak naturally.
About the WebM output
Recordings save as WebM — the browser’s native recording format. It plays directly in Chrome, Edge and Firefox, uploads fine to YouTube, Drive and Slack, and imports into modern editors. If a destination insists on MP4, our Video Compressor outputs MP4 (and shrinks the file at the same time), and the Video Trimmer cuts the fumbling start off any recording. Recording length is limited only by your device’s memory — long sessions produce big files, so for hour-plus recordings prefer a desktop with room to spare.
Honest limitations
Phone browsers generally can’t record the screen from a web page (use the phone’s built-in recorder instead) — this tool is for desktop Chrome, Edge and Firefox. And a privacy note in your favour: because everything stays local, nothing you record can leak from our side — there is no “our side”.
Frequently Asked Questions
How do I record my screen without installing anything?
Click Start Recording, choose a screen, window or tab, and stop when done — the recording previews instantly and downloads to your device. No extension, account or watermark.
Why is there no sound in my recording?
Browsers reliably capture audio only when you share a TAB (tick “tab/system audio”). Whole-screen and window shares usually come without system sound — record the specific tab, or narrate via the microphone option.
Is the recording uploaded anywhere?
No — capture happens entirely in your browser and saves straight to your device. Nothing is streamed, stored or uploaded.
What format is the recording, and can I get MP4?
Recordings save as WebM, which plays in Chrome/Edge/Firefox and uploads fine to YouTube and Drive. Need MP4? Run it through our Video Compressor, which converts and shrinks in one pass.
Can I record my phone’s screen with this?
No — mobile browsers don’t allow web pages to capture the screen. Use your phone’s built-in screen recorder; this tool is for desktop Chrome, Edge and Firefox.
