The YouTube thumbnail is the first thing viewers see about your video, and it plays a big role in people’s choice to click on your video.

When you upload a video on YouTube, it auto-generates several pre-selected thumbnails you can choose from, or lets you upload your custom-made thumbnail.

If you’ve already uploaded the video, but you are not satisfied with the low-quality auto-generated thumbnail or want to change it for your own custom thumbnail, the good news is that you can - even if the video is already published.

In this article, we’ll walk you through how to change the thumbnail on a video that’s already been published and how to add a custom thumbnail while publishing a video.

How to change a thumbnail on YouTube for a published video

Your account doesn’t allow you to upload a custom thumbnail by default. In order to enable the custom thumbnail option, you need to verify your account. Verifying your account will also allow you to upload videos longer than 15 minutes, live stream and appeal content ID claims.
