Trim a TikTok Video

Trimming a TikTok refers to shortening the length of the video. You’re essentially cutting the beginning or ending of your video.

Action: Today, I’ll teach you how to trim a TikTok video.

What is the ideal length of a TikTok video?

Answer: TikTok videos between 15 and 30 seconds usually perform better than longer or shorter ones.

1. 15–30 Seconds: Best for quick, engaging content like trends, dances, and snappy how-tos. Viewers are more likely to watch these to the end.
2. 45–60 Seconds: Great for storytelling, tutorials, or more detailed content where you need slightly more time to convey your message.
3. 1–3 Minutes: Effective for in-depth topics, vlogs, or explaining complex ideas, but only if your content keeps viewers engaged throughout.

Or take this as a “Key Takeaways” section:

Length	Best For	Notes
15–30 sec	Trends, dances, quick how-tos	Higher chance of full views, boosts algorithm performance.
45–60 sec	Storytelling, tutorials, engaging narratives	Allows more detail while maintaining attention.
1–3 min	Vlogs, in-depth explanations, complex topics	Use only if the content is engaging throughout; risks lower watch rates.

Shorter videos often perform better because TikTok’s algorithm favors high completion rates.

How to Trim a TikTok Video (within TikTok)

Upload your video to TikTok, and during editing just pull the beginning and ending corners of the timeline. This works for both mobile and PC.

1. Open the TikTok app
2. Tap “+” at the bottom
3. Select a video (or record one)
4. Tap “Edit“
5. Pull the start/finish corners of the video

This will adjust the video’s length.

Pro Tip: If you want to merge TikTok videos, the same process will be followed — pulling the corners will shrink/extend the video (trim).

How to Trim a TikTok *After Posting*

You can’t trim a TikTok after posting and keep all of its stats. You need to save and delete the current video, re-edit and trim it, then upload it again.

1. Save the Video: Open the posted TikTok, tap the three dots (...), and select “Save video.”
2. Delete the Original: Go back to the menu and choose “Delete.”
3. Edit the Video: Use an app like SendShort or CapCut to trim the saved video.
4. Re-upload: Post the edited version as a new TikTok.

Note that likes, comments, and views won’t transfer to the re-upload.

Additionally, some videos may have restrictions based on the app version or device compatibility.

2. Where is the trim option on TikTok?

The trim option on TikTok appears after you record or upload a video. Tap “Edit” on the right side of the screen to access and trim your video.

3. What is smart trim on TikTok?

TikTok’s Smart Trim is a feature that automatically shortens your video by trimming less important parts, focusing on the key moments based on audio and visual cues. It’s designed to help you quickly create concise and engaging content.
