Screen Recorder
Screen Recorder captures your whole screen, a single window or one browser tab, with optional sound from the tab and from your microphone. It records using your browser's own capture API — nothing is installed, and the video is never uploaded.
Record your screen
Your browser will ask what to share — a whole screen, a single window, or one browser tab. Recording starts as soon as you choose.
The recording never leaves your device.
A screen recording can contain messages, passwords being typed, or client work. This page captures the stream, buffers it here and saves it straight to your downloads — there is no upload step, because there is no server involved in the recording.

How to use Screen Recorder
- 01Upload
Choose your audio
Tick the microphone option if you want to narrate. System sound is offered by the browser when you pick what to share.
- 02Customize
Start recording
Your browser asks what to share — a screen, a window or a tab — and recording begins once you choose.
- 03Process
Stop and save
Pause any time, then stop and download the file. Nothing leaves your device.
What you can record
The browser asks you to choose, and the choice decides what can accidentally end up in the recording.
- A single tab
The safest option. Notifications, other windows and your desktop cannot appear in it.
- An application window
Follows that program only. Dialogs it opens may fall outside the capture, which can look confusing on playback.
- The whole screen
Everything, including notifications, other windows and anything you switch to. Necessary for demonstrating across applications, and the easiest way to record something private.
Before you press record
Silence notifications — Turn on do-not-disturb. A message preview appearing mid-recording is the most common reason a take is thrown away.
Close what should not be seen — Other tabs, bookmarks bar, desktop files and anything with a name you would not want published.
Decide about audio — System audio and microphone are separate permissions. Check you have the one you meant before recording ten minutes silently.
Do a ten-second test — Record briefly, play it back, confirm you have picture and the right sound. It costs far less than discovering it afterwards.
Length and size
- Memory is the limit
The recording is held by your browser as it goes. Long captures on a modest machine can end abruptly, so record in sections for anything lengthy.
- Keep the tab in front
Browsers throttle background tabs. Switching away from the recorder can stall the capture.
- Full screen costs more
Recording a 4K display produces far more data than a single tab. Reducing resolution before recording helps more than compressing afterwards.
Your file, and what the page does
Your file is never uploaded. Screen Recorder reads it into this browser tab and processes it with FFmpeg compiled to WebAssembly on your own device. There is no upload endpoint in the application and no copy on any server — closing the tab discards it.
That is also why processing takes longer here than on a site that uploads: your device is doing the work rather than a rack of servers. The trade is that the file never leaves it.
What the page does send or fetch
- The processing engine, once
- The first time you use any video or audio tool, the browser downloads the FFmpeg WebAssembly build (~30MB) from the jsDelivr CDN and reuses the cached copy afterwards. That is a file coming to you — no part of your own file is in the request.
- Ads on the page
- The site is funded by advertising, so the page loads Google AdSense. That carries the usual web basics — IP address, browser, referring page — as on any ad-supported site.
- An anonymous usage counter
- When Screen Recorder finishes we record that the tool ran, whether it succeeded and how long it took. No file data, no identifier, no cookie.
Your file is not on that list. How this works.
Frequently asked questions
It can record two sources: sound from what you are sharing, and your microphone. Both are mixed into a single track. Whether system sound is available depends on the browser and on what you choose to share — sharing a browser tab usually offers it, sharing a whole screen often does not.
Not from a web page. Safari on iOS and iPadOS does not implement the screen capture API at all. iOS has a built-in screen recorder in Control Centre, which is the right tool there.
No fixed one. The recording is held in your device's memory until you save it, so the practical limit is how much memory the tab can use. For long sessions, stop and download periodically rather than recording for hours in one go.
MP4 where your browser can write it, and WebM otherwise. Both play in modern browsers and video editors; if you need a specific format, the Convert Video tool will change it.
No. The capture is assembled in the page and saved straight to your downloads folder. There is no server involved in the recording at any point.
No. The file is exactly what was captured.
That bar belongs to your browser, not to this page, and ending the share ends the capture. The tool notices and saves what it has rather than pretending to still be recording.
Yes — Screen Recorder is completely free. There's no account, sign-up, watermark or limit.
No. It runs in any modern browser — Chrome, Edge, Safari, Firefox, Brave — with nothing to download or install.
