Screen Recorder Online
Record your screen, browser tab, or window with optional audio — entirely inside your browser, with no extension or download.
How does this screen recorder work?
The tool uses your browser's built-in screen capture API. When you press record, the browser itself asks which surface you want to share — an entire screen, a single application window, or one browser tab — and hands the resulting video stream straight to the page. That stream is encoded on the fly by the browser's own recorder and assembled into a WebM file you can preview and download. No plugin, extension, or desktop app is involved at any point.

Features & benefits
Why this runs entirely in your browser
A screen recording can contain anything that was visible on your display, which makes it some of the most sensitive data you could hand to a website. That is exactly why this tool never uploads it. Capture, encoding, preview, and download all happen inside the tab using the MediaDevices and MediaRecorder APIs, and the finished file only exists in your browser's memory until you save it.
Common uses
Recording a product demo or software walkthrough, capturing a bug so a developer can see exactly what went wrong, saving a portion of a video call or webinar you are allowed to record, building a quick tutorial for a colleague, or archiving an on-screen process you would otherwise have to describe in writing.
Frequently asked questions
A few things people usually want to know before they hit record.
Yes. When you press Start recording, the browser shows its own picker with three choices: an entire screen, a specific application window, or a single browser tab. The page never sees that list and cannot choose for you — the selection is made by the browser as a security measure, so a website can never silently grab your display. Tab capture is the cleanest option for web demos because notifications and other windows stay out of the frame, while window capture follows a desktop app even if you move or resize it during the recording.
System audio capture is the most restricted part of screen sharing. On Chrome and Edge you must tick the "Share tab audio" or "Share system audio" checkbox inside the browser's own share dialog — enabling the option on this page only requests it, the browser still has to grant it. Firefox and Safari support system audio far less consistently, and sharing an entire screen on macOS often provides no audio at all. If system audio is unavailable, turn on the microphone option instead so narration is still captured.
Yes. When both options are enabled the tool requests the display stream and a microphone stream separately, then mixes them into a single track using the Web Audio API before recording begins. The result is one audio track containing both sources, which is what you want for a narrated demo where you talk over app sounds or video playback. Because the mix happens live, you cannot rebalance the two levels afterwards, so it is worth doing a short test recording first to check your microphone is not being drowned out by system playback.
Recordings are saved as WebM, using VP9 or VP8 video with Opus audio depending on what your browser supports — the tool probes the available codecs and picks the best one automatically. WebM plays natively in every modern browser and in players like VLC, and most editors and platforms including YouTube accept it directly. There is no time limit built into the tool; the practical limit is your device's available memory, because the recording is held in the tab until you download it. For very long sessions, save in segments to be safe.
No. Nothing is uploaded, stored, or shared. The captured stream goes directly from your browser's screen capture API into its built-in MediaRecorder, and the finished file lives only in the memory of this tab until you choose to download it. There is no server-side processing, no account, and no analytics on the recording itself. Closing or refreshing the page discards everything immediately, so make sure you download the file before you navigate away.
