TikTok is a platform where sound plays a major role in making videos engaging, relatable, and entertaining. Whether it’s a trending audio clip, a funny voiceover, or your favorite song, the sound you choose can determine how well your video performs. However, many users sometimes post a video and then realize they used the wrong audio—or want to switch to a trending sound for better engagement.
A common question is: Can you change the sound on a TikTok video after posting it?
The short answer is No—TikTok does not currently allow users to directly replace or edit sound on a video once it has been published. This is because once a video is posted, it is processed and saved in its final form.
However, there are simple workarounds that allow you to re-edit and repost the video with a new sound, while still keeping your original visuals.

Why TikTok Does Not Allow Sound Editing After Posting
TikTok treats posted videos as completed files. This means:
- The audio and video merge into one final clip.
- Changing the sound would require reprocessing the video file.
- Allowing sound changes could cause copyright complications, especially for music.
So, to change sound, you will need to recreate the video, but you do not need to record everything again.

How to Change the Sound Using the Repost Method
This is the easiest and most common way:
Step-by-Step Guide
- Open your TikTok App and go to your profile.
- Find and open the video you want to change the sound for.
- Tap the three dots (•••) in the lower right corner.
- Select “Save video” to download the video to your device.
- Start a new TikTok by tapping the + icon.
- Upload the saved video from your device’s gallery.
- Tap the Sounds button at the top of the editing screen.
- Browse and select the new sound you want to use.
- Adjust the volume:
- Lower the original video sound to zero (so the old audio is muted).
- Increase the selected TikTok sound to preferred level.
- Add captions, filters, or text if needed.
- Repost the video.
Once reposted, you can delete the original video if you wish.

How to Add a Voiceover Before Reposting
If you want to use your own voice instead of music:
- Upload the saved video.
- Tap Audio Editing/Voiceover.
- Record your new voiceover.
- Save and post the final video.
This method works best when correcting spoken mistakes or updating narration.

How to Change Sound Without Losing Your Post’s Engagement
Sometimes, you may not want to delete the original post because:
- It already has views, likes, or comments.
- It is part of a trend timeline.
In this case, you can:
- Pin the new edited version to the top of your profile.
- Edit the caption to direct viewers to the updated video.
- Write a comment on the original post and pin the comment:
“Updated version with new audio is posted above 👆”
This helps keep your engagement while introducing the improved version.

Tips for Selecting the Best Replacement Sound
To increase reach and engagement:
- Use trending audio — such sounds often help videos go viral.
- Choose songs that match your video’s mood.
- Check if the sound is allowed for commercial use (important for business accounts).
- Browse the Trending Sounds page in TikTok’s search tab for fresh picks.
