Is there a time limit?

No. The recording is written to your disk as it goes, so its length is limited only by the free space your browser is allowed to use. Before you start, the page estimates how many minutes that is: at 1080p a minute takes about 34 MB.

Can I record the sound from my computer?

In Chrome and Edge, yes: share a browser tab and tick Also share tab audio, or share the entire screen on Windows or ChromeOS. Firefox and Safari do not give web pages the computer’s sound at all, so there you can record your microphone but not the system sound. If you ask for computer sound and none comes through, the page tells you while you record rather than after.

What format is the video?

An MP4 with H.264 video wherever the browser can encode H.264, which is almost everywhere. The sound is AAC where the browser has an AAC encoder (Chrome on Windows and macOS, and Safari) and Opus where it does not (Chrome on Linux, for example). A browser without an H.264 encoder saves WebM instead. The page says which one you will get before you press record.

Can I record on my phone?

Not from a web page: phone browsers do not let websites capture the screen. iPhones and Android phones both have a recorder built in, though. On an iPhone or iPad, add Screen Recording to Control Centre; on Android, it is the Screen record tile in Quick Settings. If you want to compress the result or turn it into a GIF afterwards, the tools on this site work on a phone.

Yes. Switch on Webcam and choose a corner and a size. The camera picture is drawn into the recording itself, not added as a separate track, so it looks the same in every player and when you share the file.

Can I keep using my computer while it records?

Yes. Switch to the window or tab you are recording and work as normal. Keep this tab open in the background; closing it ends the recording, and a recording that is cut off that way cannot be saved.

Where does the recording go?

Nowhere but your own device. While you record, the video is written to private storage that your browser keeps for this site; when you download it, it becomes an ordinary file in your Downloads folder. Start over and the stored copy is deleted; anything a closed tab left behind is cleared the next time you open this page. Your files are never uploaded.

Screen recorder — free, with no watermark and no sign-up

Record your whole screen, one window or a single browser tab, talk over it with your microphone, and put your webcam in a corner if you want your face in it. The recording is made in your browser and saved as an MP4 on your own device. There is no account to create, no watermark stamped on the video, and no time limit beyond the free space on your disk.

How to record your screen

Choose what goes in

Switch on the microphone, the computer’s sound and the webcam as you need them. The page tells you which file format this browser will write, and roughly how many megabytes a minute will take.
Pick a screen, window or tab

Your browser asks what to share. After a three-second countdown the recording starts. Switch to whatever you want to show; pause and resume as often as you like.
Stop, watch and download

Press Stop and save, or use the browser’s own Stop sharing button. The video plays right on the page, so you can check it before you download it.

What you get

No watermark and no time limit

Free screen recorders tend to stamp their logo on the video, cap you at a few minutes, or both. This one does neither. The only limit is the free space on your device, and the page shows roughly how many minutes fit before you start.

Long recordings stay light

The video is written to your browser’s own storage on disk while you record, rather than collected in memory. A ten-minute recording does not slow your computer down, and an hour is no harder than a minute.

Your voice, your sound, your face

Record your microphone, the sound from a browser tab (or the whole screen on Windows and ChromeOS), and your webcam as a picture-in-picture in the corner and at the size you choose. The camera is drawn into the video itself, so it plays the same everywhere.

What it runs on

No AI model and no server. Your browser captures the screen and encodes the video with its built-in encoder, and mediabunny, an open-source library, writes the MP4 file. Your files are never uploaded.
