In the past, if you wanted to record the screen, you had to install additional software. Now, there are more and more useful free screen recording tools on the Internet, which can be achieved through the browser, which is very convenient. The ONLINE SCREEN RECORDER recommended in this article is one of them. Chrome, Firefox, and Opera all support it. After opening this web tool, you can enable screen recording, and you can also choose to record the entire screen, an application, or a browser tab.
It also supports simultaneous recording of microphone and browser sounds, which I will quickly introduce to you below.

Open applications will be listed above, and even folders support:

The same goes for browser paging. If you just want to record the operation of a certain web page, this function is very easy to use. You don’t have to worry about other things being recorded:

As shown below, after the recording is completed, press Stop Recording to stop:

Click the download icon on the left to download the file to your computer:

Video format is Webm:

The image quality depends on the resolution setting of your computer, like mine is 2560×1080:

It’s a pity that this set does not support the pause function, which means that each recording must be recorded in one go, and there is no way to interrupt it, or to combine the clips through other editing software.
