Part 2. How to Change Background Music of Video Online Free?

Instead of downloading a desktop video editor to remove background music from a video, you can also try some online video editors to replace the background music in videos. Here are many online video editing tools now, and I’d like to take Clideo as an example to show you how to change the video background music online free.

Clideo is one of the most popular online video editors that enables users to merge, crop, rotate, resize, trim, and compress videos. It also allows you to add music to videos. Some audio editing features like cutting and merging audio are also provided.

Now, let’s see how to change background music of a video with Clideo.

Step 1. Go to the startup page of Clideo with this link ( and click “All tools” to find and open the “Add Music to Video” tool.

Step 2. Click “+ Choose file” to import the video from your local drive. You can also click the arrow icon to select a video file from your Google Drive or Dropbox account. Wait for the file uploading process.

Upload Video

Step 3. After entering the audio adding page, click the “+ Add Audio” button right next to the video view window to pick an audio file and wait for the uploading process. (Here you can also add the audio file from your Google Drive and Dropbox account.)

Step 4. Now you can set the music start time while playing, and trim the audio to shorten the audio track. You can also loop the audio when the soundtrack you add is shorter than the video. Then drop the video volume to 0%.

Step 5. At the bottom left of the window, you can choose the output format or leave it as the default (MP4). Finally, press “Export” and wait for a while.

Replace Background Music

Step 6. Before downloading the final video, you can preview it to make sure everything sounds OK. Then click “Download” to save it to your devices or upload it to your Google Drive or Dropbox account. Otherwise, you can click “Edit” to return to the previous step.

Tips. Online background music changers are easy to get started with, but there are also many drawbacks. They completely rely on the network, so the uploading and editing processes can take a long time and even crash if the network is unstable. Moreover, most online video editors limit the uploading file size and length, output quality, and add a watermark to the final video unless you upgrade to their paid plans.

Part 3. Video Background Music Changer App for Mobile

You can just search for a video editor in the App Store on your iPhone or Android phone.
