How to trim a sound on TikTok

TikTok’s built-in audio editor makes it easy to trim sounds, shorten music, sync clips, and create clean transitions. Whether you’re using an original sound, TikTok’s music library, or an uploaded audio clip, trimming allows you to control exactly which part plays in your video.

This guide breaks down every working method for trimming audio on TikTok using both iPhone and Android.

What Does “Trimming a Sound” Mean on TikTok?

Trimming a sound means cutting the audio so that it starts and ends exactly where you want. This is especially useful when you want:

• A specific beat drop
• A particular lyric
• A short soundbite
• To sync your lip-sync or transition
• To remove unwanted parts of a long audio clip

How to Trim a Sound on TikTok (Using the Built-In Trimmer)

This is the most common method and works for sounds from TikTok’s own music library.

Step-by-Step

1. Open TikTok and Tap the “+” to Create a Video

This opens the recording/editing screen.

2. Record a Video or Upload One

You can trim audio for both recorded and uploaded clips.

3. Tap “Add Sound” at the Top

This opens TikTok’s sound library.

4. Choose a Sound

Use:

• Favorites
• Trending
• For You
• Search bar

5. Tap the Scissors Icon (Trim Button)

Once the sound is selected, you’ll see the scissors/trimmer icon next to the sound preview.

6. Drag the Waveform Left or Right

• Slide the waveform to choose the exact part of the audio you want to use.
• The highlighted section is what will play in your video.

Your audio is now trimmed and ready for posting.

How to Trim TikTok Sounds After Recording

You can still trim the audio even if you already recorded your video.

Steps

1. Record or import your clip.
2. Tap Sounds at the bottom-left.
3. Tap the scissors icon.
4. Drag the slider to select the part of the sound you want.
5. Tap Done.

How to Trim Your Own Uploaded Audio on TikTok

If you upload your own sound (e.g., voiceovers, exported audio, background music), you can trim it the same way.

Steps

1. Tap Upload → select your video.
2. Tap Sounds → My Sound (or “Imported”).
3. Tap the scissors icon.
4. Drag the handles to trim the audio.
5. Save.

TikTok may restrict trimming for copyrighted music you upload yourself.

How to Trim Original Audio Recorded in Your Video

If your audio comes from your recording (talking, singing, etc.):

Steps

1. Upload or record your video.
2. Tap Volume → reduce “Original sound” or mute it.
3. Add a TikTok sound.
4. Trim the TikTok sound normally.

To trim the original sound itself directly, you will need to split the video clips:

Steps

1. Add your video.
2. Tap Edit.
3. Use Split to cut the video clip at the exact parts you want.
4. Delete the unwanted segments.

This trims both the video and the original audio.

Why Can’t I Trim a Sound on TikTok? (Common Issues)

You may not see the trimming option due to:

Try trimming before adjusting clips or effects.

3. You’re Using a Stitch or Duet

Some duets/stitches lock the sound.

4. TikTok App Bug

Fix by:

• Updating the app
• Restarting device
• Clearing cache
• Re-installing TikTok
