Part 3. Can You Change TikTok Thumbnail After Posting?

Once a TikTok video is posted, the platform does not currently allow users to change the TikTok thumbnail after posting. Unlike YouTube, where thumbnails can be updated at any time, TikTok locks the selected cover once a video goes live.

Alternative Solution: Delete and Re-upload

If you need to update the TikTok video thumbnail, the only way is to delete and re-upload the video with the desired cover. Here's how:

Step 1. Open TikTok and go to your profile.

Step 2. Find the video and tap on it.

Step 3. Tap the Three-dot menu (•••) on the right side.

Step 4. Select Delete and confirm.

Step 5. Re-upload the video, following the steps in Part 1 to choose the right thumbnail for the TikTok video.

Potential Drawbacks

While this method works, it comes with some downsides:

  • Loss of engagement – All likes, comments, and shares on the original post will be lost.
  • Reposting effects – Followers may see the re-uploaded video as a duplicate, which could affect engagement.

Since TikTok doesn't currently support changing thumbnails after posting, it's essential to select the best thumbnail before uploading to avoid these issues.

Conclusion

Knowing how to change the thumbnail on TikTok can help make your videos more visually appealing. Since TikTok only allows you to select a frame before posting, choosing the right TikTok video thumbnail is important for engaging viewers. If you need more customization, third-party tools like Filmora offer advanced editing features to create eye-catching thumbnails.

Currently, TikTok does not support how to change the TikTok thumbnail after posting. The only option is to delete and re-upload the video, which may result in losing engagement. To avoid this, selecting the best thumbnail before posting is essential.
