Screen Recorder
Record your screen, a window or a single browser tab in up to 4K, with system audio, your microphone and a webcam corner. No watermark, no sign-up, no time limit, and nothing is uploaded.
Nothing is being captured yet
Choose what to record on the right, then press Start. Your browser will ask which screen, window or tab to share.
The recording is written on this device and never uploaded.
A screen recording is unlike almost every other file this site handles, because it does not exist until the moment it is made. There is no source to go back to and no second attempt at a frame that was missed — which makes the interesting engineering here not the encoding but everything arranged around it so a take cannot quietly be lost.
The clearest example is sound. A muted microphone behaves exactly like a working one: no error, no warning, nothing to notice. You find out at the end, when the take is gone. So the microphone is opened and metered before the Start button does anything, and the interface refuses to call it working until the meter has actually moved. Say a few words first; it takes two seconds and saves the recording you would otherwise have made twice.
The same reasoning runs through the rest. Stopping from the browser's own sharing bar never reaches this page's buttons, so the recording is ended from the capture stream itself and everything up to that moment is kept. Frames go straight from the screen to the encoder whenever nothing needs compositing, because at 4K60 an unnecessary canvas is the difference between keeping up and dropping frames. And the file is written a second at a time rather than assembled at the end, so the size you see is real.
None of it is uploaded. That matters more for screen recordings than for most things, because what is on your screen is usually your email, your customer data, your unreleased work, or your colleagues' faces.
How to record your screen
-
1. Choose what to capture
Entire screen, a single window, or one browser tab. A window keeps recording the same application even when you click elsewhere, and a tab is the cleanest way to capture audio playing in the page.
-
2. Set the resolution and quality
Same as source is sharpest and cheapest, because nothing is rescaled. Pick an explicit 4K, 1440p, 1080p or 720p when you need a fixed output size. Quality is set per pixel, so one setting means the same thing at every resolution.
-
3. Add sound and camera
Turn on system audio, the microphone, or both. If you use the microphone, watch the level meter and say something before you start — this is the step that prevents a long recording with no sound. Add a webcam inset if you are narrating.
-
4. Press Start and pick the surface
Your browser shows its own picker. Choose the screen, window or tab, and a countdown gives you a few seconds to get into position before anything is captured.
-
5. Record, pause, stop
A timer and the running file size are shown throughout. Pause and resume as often as you like — the pauses are simply not in the file. Stopping from the browser’s own sharing bar also ends the recording cleanly and keeps everything captured so far.
-
6. Play it back and download
Watch the result before you close the tab, then download. Nothing was uploaded at any point, and nothing is kept once the tab closes.
Screen, window or tab
-
🖥 Entire screen
Everything, including other applications and anything that pops up. Best for showing a workflow across several apps — and the one to be careful with, since notifications land in the recording too.
-
🪟 A window
One application, and it stays on that application even when you click elsewhere. No system audio, though — the capture API does not offer it for a single window.
-
🌐 A browser tab
The safest and the best for sound. Nothing outside that tab can appear in the file, and tab audio is the most reliably captured kind.
About 4K, honestly
This records at whatever the shared surface provides, up to and including 4K, and Same as source keeps it exactly. What no recorder can do — this one included — is invent detail that was never on the screen. Choosing 4K while sharing a 1080p display gives you a 4K file containing an upscaled 1080p picture: four times the bytes, no extra sharpness, and a longer encode.
So if your display is 4K, share it and leave the setting alone. If it is not, record at its real resolution. The one good reason to pick an explicit size below the source is to get a smaller file or a fixed output for somewhere with an upload limit — going upwards is only ever worth it when something downstream demands a specific frame size.
A related note on size: a full-screen 1080p capture at 30 fps and Balanced quality runs roughly 50 MB a minute, and 4K at 60 fps is several times that. Quality here is set in bits per pixel rather than as a flat bitrate, so one setting means the same thing at every resolution — and Small file is genuinely the right choice for slides, where the picture barely changes and extra bitrate buys nothing at all.
What it cannot do
It cannot record a phone. Screen capture from a web page does not exist on iOS or Android; no website can record a phone screen. Both systems have a built-in recorder in their own settings.
It cannot capture window audio. Chrome and Edge offer system audio for a tab or a whole screen but not for a single window, and Firefox and Safari do not offer it at all. That is the operating system's capture API, not this page. The microphone works everywhere.
It cannot highlight clicks outside this page. A web page is never told about clicks in other windows, which is a deliberate part of the browser's security model. Click highlighting is genuinely useful for recording this tab and does nothing at all for anything else.
It is not an editor. Trim the ends with the video trimmer, clean the sound with the audio editor.
Frequently asked questions
Is this really free, with no watermark and no time limit? +
Yes. There is no watermark, no sign-up, no account, no trial, and no cap on how long you record. There is nothing to pay for because there is no server cost to cover — the recording is made and encoded by your own browser, so nothing is uploaded and no storage or bandwidth is consumed on our side. The only real limit is your own disk space.
Is my recording uploaded anywhere? +
No. The video is captured, encoded and saved entirely on your device, and no part of it is transmitted anywhere. This is worth caring about for screen recordings in particular: what is on your screen is usually your email, your customer data, your unreleased work or your colleagues’ faces. A recorder that uploads is handing all of that to someone else.
Can it really record in 4K? +
It records at whatever the shared surface actually provides, up to and including 4K, and Same as source is the setting that preserves it exactly. What no recorder can do is invent detail: choosing 4K while sharing a 1080p screen produces a 4K file that contains an upscaled 1080p picture — larger, not sharper. If your display is 4K, share it and leave the setting on Same as source.
My recording has no sound. Why? +
Almost always because the share-audio box was not ticked. Chrome and Edge put a "Share system audio" or "Share tab audio" checkbox in the sharing dialog, it is off by default, and it is easy to miss — asking for audio here does nothing unless you also tick it there. Three other causes are worth knowing: system audio is not offered for a single window at all, so record a tab or the whole screen if you need it; Firefox and Safari do not offer system audio in any case, so use the microphone there; and a muted or wrong microphone will produce silence with no error. The recorder now meters the sound actually reaching the file while you record, and warns on screen if nothing is arriving — check that meter is moving in the first few seconds rather than discovering it at the end.
How do I record just one browser tab? +
Choose "A browser tab", press Start, and pick the tab in the browser’s picker. Tab recording has two real advantages: nothing outside that tab can ever appear in the file, which removes the risk of catching a notification or a private message, and tab audio is the most reliably captured kind. It is the right choice for recording a web app, a video call in the browser, or a slide deck presented in a tab.
Can I record the sound as well as the picture? +
Yes. There are two separate sources: the screen or tab’s own audio, and your microphone, and you can use either or both. System audio needs the share-audio box ticked in the browser’s sharing dialog and is not available for a single window, or in Firefox and Safari. The microphone works everywhere regardless, so a narrated recording is always possible even where system audio is not.
Why does the microphone meter matter so much? +
Because a dead microphone is invisible until it is too late. A mic muted at a hardware switch, or a browser pointed at the wrong input, behaves exactly like a working one — no error, no warning — and you find out forty minutes later when you play the file back and the take is gone. So the microphone is opened and metered before recording starts, and the interface will not claim it is working until the meter has actually moved. Say a few words and watch the bar before you press Start.
What file format do I get? +
MP4 where your browser can produce it, which recent versions of Chrome and Edge can, and WebM otherwise. MP4 plays on essentially everything without conversion, which for a recording heading straight into a ticket, an email or a chat matters more than the few per cent of file size a newer codec would save. If you get WebM and need MP4, our video trimmer can convert it.
Can I pause and carry on? +
Yes, as often as you like. Paused time is not recorded at all rather than recorded and cut, so the file has no gap and no jump in the timer. It is the easiest way to skip a dull wait — a build running, a page loading — without editing afterwards.
What if I stop sharing from the browser’s own bar? +
The recording is finalised and everything captured up to that moment is kept. That bar is outside the page and clicking it never reaches these buttons, so the recording is ended from the capture stream itself instead. A recorder that only listens to its own Stop button loses the whole take when someone uses the browser’s.
Why is my file so large? +
Screen recordings are large by nature: a full-screen 1080p capture at 30 fps and Balanced quality is roughly 50 MB a minute, and 4K at 60 fps is several times that. Quality here is set in bits per pixel, so it means the same thing at every resolution — drop to Small file for slides and mostly static screens, where the picture barely changes and the extra bitrate buys nothing. Recording at 1080p rather than 4K is the single biggest saving.
Does the click highlighting work everywhere? +
No, and it is worth being clear about why. It can only show clicks made on this page. A web page is never told about clicks in other windows or other applications — that is a deliberate part of the browser security model, not something a tool can work around. So it is useful when recording this tab and useless when recording something else, and the setting says so rather than letting you find out in the finished file.
Can I record on my phone? +
No. Screen capture from a web page does not exist on iOS or Android — mobile browsers have no equivalent API, and no website can record a phone screen. Both systems have a built-in screen recorder in their own settings, which is what to use there.
Can I edit the recording afterwards? +
Trim the false start and the fumble at the end with our video trimmer, which cuts frame-accurately without re-recording. If the audio needs work, the audio editor will clean up background noise and set the level to a proper broadcast target, and the video-to-GIF tool will turn a short section into a GIF for a bug report.
