Yes. You can change a YouTube video thumbnail after upload. Open the video in YouTube Studio, choose an available suggested image or upload a custom thumbnail, then save. YouTube says the change may take time to appear.
This guide covers standard videos first. Shorts use separate thumbnail controls, so check the Shorts section before following the regular-video steps.

How do you change a standard video's thumbnail?
Edit the existing video's details in YouTube Studio. YouTube's computer instructions are:
- Sign in to YouTube Studio.
- Choose Content from the left menu.
- Click the video's title or thumbnail to open its details.
- Under Thumbnail, choose a suggested image or upload a file if the option is available.
- Select Save.
YouTube's video settings guide confirms that video details can be changed after upload. Its thumbnail instructions explain how to choose a suggested image or upload a custom one.
You are editing the thumbnail setting for the video already in your channel. This is different from deleting the video and uploading a replacement. Do not re-upload just to try a new preview image.
Can you upload a custom thumbnail?
YouTube says your account must be verified to upload a custom thumbnail. If you do not see the upload option, check the channel's verification and feature eligibility in YouTube Studio. You can also choose from the suggested thumbnail images when available.
| Thumbnail choice | What it means | What to check |
|---|---|---|
| Suggested image | Select an image YouTube offers for the video. | Pick the frame that best represents the video. |
| Custom image | Upload an image from your device. | YouTube requires a verified account for custom thumbnails. |
| Shorts frame | Choose a frame from the Short using the Shorts controls. | Shorts use a separate workflow and can have different limitations. |
Thumbnail availability and rules can differ for Shorts. Do not assume the custom-image options for a standard video work the same way for a Short.
Can you change a YouTube Shorts thumbnail?
Shorts use a separate thumbnail workflow. YouTube's Shorts Help article says you can choose a frame for a Short before or after upload, and its after-upload steps use the YouTube app rather than YouTube Studio.
- Open the YouTube app and go to your channel page.
- Open Your videos and find the Short.
- Open its menu and choose Edit.
- Select a frame to use as the thumbnail, then tap Done.
YouTube says this Shorts workflow selects a frame from the video. Its custom-thumbnail guidance is separate, so check the current YouTube Shorts instructions for the options available on your device.
Why has the new thumbnail not appeared yet?
YouTube says thumbnail changes may take time to appear. Save the setting in Studio, then give the update time to show on YouTube before changing it again.
If the thumbnail still looks unchanged, reopen the video's details and confirm that the new choice was saved. Also check the video on another YouTube surface, since an already-open page or cached preview may not refresh at once.
There is no exact update time in YouTube's help article, so avoid relying on a promised number of minutes or hours.
What should you check before saving?
Make sure the selected image accurately represents the video. A thumbnail sets the preview viewers see before choosing a video, so it should not promise content that is not in the video.
- Accuracy: match the image to what the video actually shows.
- Readability: check that the main subject remains clear at a small size.
- Eligibility: confirm that your account can upload a custom thumbnail if you need one.
- Format: use YouTube's current guidance for the video type and upload device.
- Save status: return to the video's details and confirm the new thumbnail is selected.
Thumbnail impressions and video views are different measures. For the current distinction, see our guide to what counts as a YouTube view. If you are comparing video engagement options, review the current requirements on the YouTube Views and Likes service page before submitting a video link.
