If you've added an original sound to TikTok that other creators have used on their videos, you can choose to remove that sound at any time. Once you remove the sound, it will be permanently removed from all videos that use that sound, including your own.
How to remove an original sound on TikTok
To remove your sound from all TikTok videos:
1. In the TikTok app, tap the sound at the bottom of the video to go to the original sound screen.
2. Tap the Share button at the top.
3. Tap Remove sound, then tap Remove on the next screen and confirm to delete the sound from all videos that use it. This includes your video as well as other videos from creators that used your sound. Creators will be notified that the sound has been removed from their video.
