There are many free tools for downloading YouTube and online videos on the market. The characteristics of Vividl are that it is small in size, easy to operate, supports hundreds of websites, and is an open program code. It also provides installation-free files. It is very suitable for people who do not want to install too many software on their computers. I will introduce it to you below.

Vividl is a free open source video downloader that supports hundreds of websites such as YouTube, FB, and IG.
After entering the Vividl download point, if you want to download the installation file, you can click Download directly. If you want to download the installation-free file, please scroll down the page, and then find the Portable download point in Project Activity. Please download Portable.zip:

Therefore, if you want to download a video (image + sound) above 1080p, you must download the image and sound separately, and then merge them through other software, which is a little more troublesome:

After setting up, you can click the download icon on the right, and the storage location can be modified in the path above:
