Why can’t I change thumbnail on Shorts?
There are two main reasons why this doesn’t work:
Simplification: In 2022, YouTube removed the option to upload custom thumbnails through YouTube Studio for desktops.
Mobile users: Currently, you can only select a thumbnail from a few auto-generated options when uploading through YouTube Studio on desktop.
Here’s what YouTube said on X (Twitter) :
FIX: How to change thumbnails for YouTube Shorts
To set a custom thumbnail for Shorts, choose a frame during upload on mobile or design a custom one and add it to your video before uploading.
1. Before uploading
A. Use a frame from your Short
Start uploading your Short
Look for a pencil icon next to the auto-generated thumbnail.
Tap that
Choose the frame you want as a thumbnail
B. Edit the thumbnail within your Short
Create a thumbnail
When editing the Short, add it as the last frame
Start uploading the video
Select that frame as your thumbnail
This way, the custom frame you designed becomes the thumbnail when you upload the Short.
2. After uploading
If you’ve already uploaded a Shorts and want to change its thumbnail, it’s too late — sorry. YouTube doesn’t let you change the thumbnail after upload.
Though, they might be working on it — check this out:
No clear sign yet, though we know they’re aware of our needs.
