To change a YouTube Short’s thumbnail, first decide whether you want to select a frame from the video or use a separate image file. You choose a frame in the YouTube app; to upload a custom image, use YouTube Studio on a computer.
You can make either change before or after publishing, but the workflows are different. A saved change may take time to appear, so check the Short itself rather than assuming an immediate update.
Choose between a video frame and a custom image
A thumbnail can come from the Short itself or from a separate image you prepare. That distinction determines where you go: use the YouTube app to select one of the video’s frames, or Studio on a computer to upload an image file. Studio is not the place to select a frame from the video.
| What you want | Where to do it | Image source | Account note |
|---|---|---|---|
| Choose a different moment from the Short | YouTube app | A frame from the video | YouTube’s frame-selection instructions do not specify the verification requirement described for custom uploads |
| Use a designed image instead | YouTube Studio on a computer | A separate image file | YouTube says custom thumbnail uploads require a verified account |
Choosing a frame is usually the straightforward route if the video already contains a clear, well-composed moment. It avoids preparing another file, and YouTube’s app also allows you to add text or apply filters to the selected frame. A separate image gives you more control over the artwork, but you have to create an image that works in the Shorts format and meet the account requirement for custom thumbnail uploads.
A thumbnail is one of the things a viewer may see when encountering a Short in search or on your channel page. TeamYouTube has described it as an opportunity to entice viewers, not as a guarantee of more views. Choose an image that accurately represents the video and remains legible at a small size; changing it cannot assure a particular audience or result. For other channel presentation choices, see our guide to highlighting chat messages on a stream.
Change the selected frame in the YouTube app
YouTube’s documented frame-selection workflow is in its app. The labels and their placement can differ as the app changes, but the main steps are to open the Short’s thumbnail editing control, choose a frame, and confirm it.
For a Short you are preparing to upload, sign in to the YouTube app and continue through the creation flow to the final upload screen. Find the thumbnail preview, tap Edit on it, and move through the video until you reach a frame you want to use. Tap Done to confirm. You can also add text or apply a filter to the selected frame using the available controls.
Take a moment to check the result before finishing the upload. Look for a frame where the subject is visible, the moment makes sense without sound, and any text is readable on a phone. If the preview is small, that is useful: it gives you a rough idea of how the thumbnail will read when viewers encounter it in a compact format. Avoid covering a face, product, or other important detail with text.
The frame does not have to be the first moment of the video. Scrub through the Short and look for a point that represents what follows. For a devotional clip, that might be a clear view of the singer or altar; for a study Short, it could be the finished diagram rather than an opening shot of a blank page. The image should set an honest expectation for the content.
If a control is missing, check that you are editing the Short in the YouTube app rather than looking for a frame selector in Studio. YouTube’s Android instructions for creating Shorts describe selecting a thumbnail frame in the app. The wording and screen layout may vary by device and app version, so follow the purpose of the control rather than relying on an exact screen position.
Edit a Short before or after upload
You can select a frame before upload or change it later. For an existing Short, open your channel page in the YouTube app, go to Your videos, find the Short, and open its More menu. Choose Edit, then tap Edit on the thumbnail image, select the frame you want, and tap Done. Review any other edits you have made before saving or leaving the screen.
Before upload, the thumbnail choice is part of the creation and upload flow. After upload, you are changing an existing Short, so make sure you opened the right item. If your channel has several similarly named clips, use the thumbnail and title to confirm you are editing the intended video. A mistaken edit is inconvenient, but checking the item first is easier than trying to diagnose why a different Short changed.
The two situations share the same basic frame-selection action, although you enter it from different places. For a new upload, proceed to its final upload screen; for a published video, open the existing Short from your videos list and edit it. You do not need to re-upload the video just to choose a different frame.
If you are also planning a longer pre-recorded programme, the publishing decisions are different from editing a Short. Our guide to streaming pre-recorded worship services without a PC running covers that separate workflow; it is not needed to change a Shorts thumbnail.
Upload a custom image in YouTube Studio
Use a computer and YouTube Studio when you want a separate image file rather than a frame from the video. Sign in to Studio, select Content, then Shorts, and open the Short’s edit or details page. Under Thumbnail, upload the image file and save the changes. This is the custom-image workflow; do not look for it in the YouTube app’s frame-selection control.
Before you upload, check that the file is the intended image and that it represents the Short accurately. If the thumbnail section or upload control is unavailable, confirm that you are editing the correct Short and that the account meets YouTube’s stated requirement for custom thumbnail uploads. YouTube says the account must be verified for this feature. Verification is an account setting, not something supplied by an image editor.
YouTube’s computer instructions for adding custom thumbnails give the Studio route and account guidance. They recommend a 9:16 aspect ratio for a Shorts image. Follow the current Help instructions if the labels or page arrangement differ from what you see, since YouTube can update its interface.
If you are creating artwork separately, keep the main subject and any essential text near the centre of the image. A tall design can be cropped or displayed differently in different contexts, and small lettering may not remain readable. Preview it at a compact size before uploading. A simple image that clearly identifies the Short is often more useful than a crowded design with several competing elements.
Check verification and aspect ratio
The verification requirement applies to uploading a custom thumbnail image, according to YouTube’s Help guidance. If you cannot upload a file, check whether the Google account associated with the channel has completed YouTube’s verification process and whether you are signed in to the right channel. Do not assume that a missing control means the image file is defective.
For a Shorts custom image, YouTube recommends a 9:16 aspect ratio. That is a recommendation from YouTube, not a promise that every surface will show every pixel exactly as you designed it. Keep key content away from the outer edges, and preview how the subject and text look when the image is displayed small.
Frame selection and image upload should not be confused when checking eligibility. The frame method uses a moment from the video in the YouTube app; YouTube’s custom-thumbnail guidance specifies verification for a separately uploaded image in Studio. If you only need a clearer still from the Short, try the app workflow first. If you need an illustration, title card, or branded design that is not present in the footage, use the custom-image route.
Save, then verify what viewers can see
After selecting a frame, tap Done and finish or save the edit as the app directs. After uploading an image in Studio, use the page’s Save control. A thumbnail change may take time to appear, and YouTube does not provide an exact display time in the cited guidance. Do not treat the first view of an old thumbnail as proof that the edit failed.
Check the Short from the channel’s content list or its viewing page after saving. Confirm the title and video are the right ones, then look at the displayed thumbnail. If you use a phone and a computer, check on both when practical; the display may not refresh at the same moment everywhere. Avoid making repeated edits simply because one place still shows the earlier image. First give the change time to appear and refresh the page or app.
A useful verification check is specific: can you identify the intended frame or image, and does it belong to the Short you edited? If not, return to the relevant workflow and check that the edit was saved. If the chosen frame is correct in the app but a separately uploaded image is what you intended, you used the wrong method; select the right route rather than repeating the same steps.
For creators who also publish long-running channel programming, thumbnail work is a separate task from keeping a live broadcast running. If a pre-recorded video is part of a continuous channel, our continuous YouTube live stream settings guide addresses stream configuration, not Shorts artwork. StreamNeo can remove the need to keep your own computer running when you want an uploaded video to run as a 24/7 YouTube live stream; that is a different use from changing a Short’s thumbnail.
Troubleshoot a thumbnail that has not updated
Start by identifying which method you used. If you selected a frame in the app, reopen the Short’s edit controls in that app and check that you tapped Done. If you uploaded a custom file, revisit the Short in Studio on a computer and confirm that you saved the edit. These paths are distinct, so repeating the other method will not confirm that your original change was saved.
Next, verify the account and item. Make sure the channel shown in the app or Studio is the one that owns the Short, and confirm the title or content before changing anything again. For a custom image, check the account verification requirement and the image under Thumbnail. If the upload control was absent, verify the current account status and consult YouTube’s current Help page rather than guessing at a workaround.
If the saved image is correct but you still see the old one, allow time for the display to catch up. YouTube notes that a change may take time to appear, but does not give a fixed waiting period. Refresh the page or app, then check again later. The same thumbnail can be cached or displayed differently in places you have already opened, so compare the current video page with the content list rather than relying on one stale screen.
If the wrong image appears after the display has had time to update, edit again using the matching workflow and save once. For a frame, use the YouTube app; for a separate file, use Studio on a computer. Keep a copy of your custom image so you can compare it with the uploaded result, and note which channel and Short you changed if you manage more than one. Avoid making several changes in quick succession, since that makes it harder to tell which saved version you are checking.
