Question 1

Is there a time limit on how long I can record?

Accepted Answer

No. Nothing in the page stops a recording or counts minutes. The limit is your computer: the recording is kept by the browser until you download it, and full HD is recorded at about 5 megabits a second, which is roughly 2 GB an hour. An hour or two is fine on most computers; for a session of several hours, stop and start a new recording now and then.

Question 2

Will the video have a watermark or this site’s name on it?

Accepted Answer

No. The video is exactly what you shared, plus your webcam bubble if you turned it on. Nothing else is drawn on it, and there is no account to make or plan to upgrade.

Question 3

Can it record the sound playing on my computer, not just my voice?

Accepted Answer

In Chrome and Edge, yes: tick Include computer or tab sound, then turn on the audio switch in the browser’s sharing picker - Share tab audio when you pick a tab, or Share system audio when you pick the whole screen on Windows. A single window is always shared without its sound. Firefox and Safari do not share sound with a web page at all, so there the recording has your microphone only. When both are on, the page mixes the screen’s sound and your microphone into one soundtrack.

Question 4

Why did my screen recording save as WebM rather than MP4?

Accepted Answer

Because the browser could not record MP4, or WebM was chosen as the file type. Firefox records WebM, and Chrome and Edge fall back to it on computers where they cannot make MP4. VLC and web browsers play WebM, but if an app wants MP4, download the recording and open it in the Video Compressor on this site, which converts WebM to MP4 and can trim the start and end too.

Question 5

Does my screen recording go to a server?

Accepted Answer

No. It is recorded by your browser and kept in this tab; the page does not upload it, and Download writes the file from the tab straight to your computer. Close the tab without downloading and it is gone.

Question 6

Can I record my screen on a phone or iPad with this?

Accepted Answer

No. Phones and tablets do not give web pages screen sharing, so this needs a desktop or laptop with Chrome, Edge, Firefox or Safari. iPhones and iPads have a Screen Recording button in Control Centre instead, and recent Android phones a Screen record tile in Quick Settings.
