Adding music to video online is a good choice because you don’t need to install any video editing software on your computer. Sometimes, if the desktop video editing app installed doesn’t have a library of royalty-free music, you have to uninstall and try other software. With online solutions, you won’t worry about this. There are several online video editors you can use to add music to a video for free. In this article, I’ll share with you about how to add music to video online.
