How to change music on a TikTok post

If you’ve already uploaded a video and later realized you want to swap the audio, you may be wondering how to change music on a TikTok post. Many creators find themselves wanting to update their sound because a trend changes, a song becomes copyrighted, or they simply want their video to perform better. While TikTok gives users powerful editing tools, its rules around editing published videos are strict—meaning you cannot directly replace audio on a post once it goes live. However, there are several effective workarounds.

This guide explains everything you need to know, including what you can change, what TikTok does not allow, and the best solutions to update your audio.

Can You Directly Change Music on a Posted TikTok?

The short answer: No, TikTok does not allow changing or replacing music on a video that is already published.

Once the post is live, TikTok locks the audio track to protect copyright integrity and prevent misuse of trending sounds.

However—TikTok does allow you to repost, re-edit, or save and replace your content using alternative methods.

Method 1: Remove the Video and Re-upload With New Music

The most common and effective solution is to:

1. Save your original video
2. Delete the published version
3. Re-upload it with new sound

Step-by-step process:

1. Open TikTok and go to your Profile
2. Find the video you want to update
3. Tap the three dots (…)
4. Select Save video
5. Go back and delete the original video (optional but recommended)
6. Tap the + button to upload the saved video
7. Choose your new music from the Sounds library
8. Edit and post as normal

This method preserves your content but gives you full control over sound selection.

Method 2: Use the “Duet with Yourself” Trick (Sound Replacement Hack)

If you don’t want to delete the original video, you can use the duet feature to essentially create a new version with new sound.

Steps:

1. Open your posted video
2. Tap Share > Duet
3. Choose the full-screen layout
4. On the right-side menu, tap Add sound
5. Select the new music you want
6. Record or upload your original video again
7. Post the duet as your updated version

This keeps the old video online while giving you a fresh one with updated audio.

Method 3: Re-edit the Video Using a Third-party Editor

Apps like CapCut, InShot, or VN Video Editor allow you to:

• Remove the original audio
• Add new music
• Adjust sound levels
• Add effects or transitions

Steps:

1. Save the video from TikTok
2. Open it in your preferred editing app
3. Delete or mute the original sound
4. Add your new music track
5. Export and upload it back to TikTok

This method is ideal if you want advanced audio control.

Method 4: Use TikTok’s “Adjust Clips” Tool Before Posting

While you cannot change music after posting, you can change it before your video goes live.

Steps while editing:

1. Record or upload your video
2. Tap Sounds to pick music
3. If you change your mind, tap Sounds again
4. Choose a different track
5. Tap Adjust clips to sync sound with video
6. Finalize and post

This ensures your audio is timed perfectly before publishing.

What to Do If the Music Becomes “Muted,” “Private,” or “Removed”

Sometimes TikTok removes or mutes certain music due to copyright updates. If this happens:

1. Save your unmuted original (if possible)
2. Delete the affected post
3. Re-upload with a trending sound that is copyright-approved

TikTok’s audio library constantly changes, so choosing official or royalty-free sounds is safest.

Tips for Choosing the Best Music for Your TikTok Post

• Use trending sounds to increase reach
• Choose music that matches the mood of your video
• Avoid copyrighted music from outside TikTok
• Adjust the volume so your voice (if any) stays clear
• Keep an eye on TikTok’s recommended “For You” sounds

Good audio selection increases watch time and boosts discoverability.
