# Add and edit subtitles on TikTok

By HeyMark · Updated October 16, 2026

Before editing, check that the text you want to change is in the caption track, not the post description or text embedded in the video file. The steps below cover a track on a published video and creator captions in a post preview.

## Edit auto-generated captions on a published video

1. Open your profile and choose a video that has auto-generated captions.
2. Tap the caption track and select **Edit captions**.
3. Correct lines that do not match the speech, or delete lines you do not want to show.
4. Tap **Save**, then replay the section to check the result.

This path applies to auto-generated captions available on the video; it does not edit the post caption or text embedded in the original video file.

## Edit creator captions before posting

1. Tap **Add post** and record or upload your video.
2. In the preview, open **Captions** in the side panel. The first time, TikTok may ask you to turn on the feature and agree to its terms.
3. Review the transcript and edit lines one by one; save when finished.
4. Check the text and timing before continuing to the posting screen.

TikTok can also generate auto captions for eligible videos: on the posting screen, tap **More options**, choose **Select video language**, and select the language, then continue with **Post** if the video is eligible. Availability may vary; if you do not see a tool or caption track, do not assume the post description replaces it.

### Fictional example

In a bakery video, the speaker says “sourdough,” but the transcript reads “sour dough.” If it is an auto-generated track on a published video, open that track and correct the line. If you are preparing the post and using creator captions, edit it in the preview before sharing. Replay the section and confirm each word. This example is fictional and was not tested on an account.

## Check before you finish

- First identify whether you are editing auto captions on a published post or creator captions in a preview.
- Listen to the beginning, a section in the middle, and the end.
- Check names, numbers, and negations against the audio.
- Save and replay the section; if the error is embedded in the file, correct the original project.

[TikTok's accessibility and captions Help page](https://support.tiktok.com/en/using-tiktok/creating-videos/accessibility) describes both workflows. Its [editing and posting guide](https://support.tiktok.com/en/using-tiktok/creating-videos/editing-posting-and-deleting?lang=en) covers other editing tools.

## Frequently asked questions

### Can I edit TikTok captions after posting?

Yes, for auto-generated captions: open the video, tap the caption track, choose Edit captions, change or delete lines, and save.

### How do I edit creator captions?

While preparing the post, open Captions in the preview's side panel, edit the lines, and save before posting.

### Are captions the same as a TikTok post caption?

No. Captions transcribe speech on the video; the post caption is its written description.
