Screen Recorder
100% private — runs on your device, never uploaded. Works offline once loaded.
Record your screen (and optionally microphone audio) right in your browser and download the video — no watermark, no sign-up, no upload. The recording is captured and saved entirely on your device.
What happens when you click Start
Clicking Start triggers your browser's built-in screen-sharing picker (the same dialog used for video calls), which asks you to choose a specific window, browser tab, or your entire screen. Once you pick one, the browser's MediaRecorder API encodes the video frames on the fly — typically as VP9 or VP8 inside a WebM container — and streams the encoded chunks into memory until you press Stop, at which point they're assembled into a single downloadable file.
Common reasons people record their screen
This isn't just for gamers — it's one of the most useful tools for anyone who needs to show, rather than describe, what's happening on a screen.
- Recording a bug reproduction for a developer instead of writing three paragraphs describing it
- Making a quick software walkthrough or tutorial without editing software
- Capturing a video call or webinar locally for later reference
- Recording a client demo to send asynchronously instead of scheduling a live meeting
Format and browser support notes
The output is a WebM video file, which plays natively in Chrome, Firefox, Edge and most modern video players and web pages, but some older desktop software (older Windows Media Player builds, some video editors) may expect MP4 and need a quick conversion first. Recording quality follows your source display's resolution and frame rate — there's no artificial compression pass, so a 4K display produces a correspondingly larger file than a 1080p one.
Screen capture support also varies by browser: Chrome, Edge and Firefox on desktop all support it well, but Safari's support for capturing the screen has historically been limited, so recordings are most reliable on a desktop Chromium or Firefox browser.
Getting clean audio into your recording
Most browsers offer a separate 'share audio' checkbox in the screen-picker dialog for system or tab audio, independent of the microphone permission for your voice — for a narrated tutorial you'll usually want both enabled, while a silent UI demo can skip the microphone entirely to avoid picking up background noise.
Frequently asked questions
Is my recording uploaded?
No — it is captured and saved entirely on your device. Nothing is sent to a server.
Is there a watermark or time limit?
No watermark and no artificial limit — recording length is only bounded by your device.
Is my screen recording uploaded anywhere?
No — capture, encoding and the final file all stay on your device; nothing is sent to a server at any point in the process.
Is there a watermark or a maximum recording length?
No watermark is added and there's no artificial time cap — the practical limit is just your device's available memory for the recording session.
Can it capture system audio and my microphone at the same time?
Yes, if your browser's share dialog offers both options — check the 'share audio' box for system/tab sound and grant microphone access separately for your voice narration.
What file format do I get, and will it open elsewhere?
You'll get a WebM video file, which plays in modern browsers and most current media players; if a specific app requires MP4, you may need to convert it first.
Does screen recording work on iPhone or Safari?
Screen-sharing APIs are most reliably supported on desktop Chrome, Edge and Firefox — mobile Safari and iOS browsers generally don't support capturing the screen through the browser.
Can I record just one browser tab instead of my whole screen?
Yes — the screen-picker dialog that opens when you click Start lets you choose a single tab, a specific application window, or the entire display.
