How to Change YouTube Thumbnails on a PC (With Pictures).
Creating creative thumbnails for your YouTube videos is one of the most important things you should consider to develop your YouTube channel.
If your YouTube video thumbnails are attractive and creative, it will help you attract more people to watch your videos and then rank higher. However, if you use the low-standard thumbnails automatically generated by YouTube, it will be more difficult for anyone to increase views on your YouTube channel. I won’t tell you how to make a cool thumbnail for your YouTube videos in this post, but you can find out how to change the thumbnails for your YouTube videos in 2023 here.
This way to change YouTube thumbnails can be used to upload and publish videos. Please leave your questions in the comment section at the bottom. How do I change the thumbnail of a YouTube video in YouTube Studio?
You cannot directly change the thumbnails of your YouTube videos on the YouTube channel; you need to use YouTube Studio to help you with this.
First of all.

Log in to YouTube Studio by clicking the title here or selecting it under your profile icon.
Second.

Click “Content” on the sidebar and select the video you want to change the thumbnail of.

Third.

Continue scrolling down the video edit page until you reach the “Thumbnails” section (Skip Title and Description).

If you haven’t used any custom thumbnails before, just click the first box here. For those already using non-auto-generated thumbnails for your videos, click the three dots on the top right of the first box to open “Options”.
Then, click convert.

Go to the folder with your custom thumbnail that you want to change for your YouTube video and select it.
After you select a thumbnail, click “Open”. By the way, make sure the thumbnail size is 2MB or below; otherwise, YouTube won’t allow you to use a large image as a video thumbnail.
If you’re happy with the latest thumbnail you’ve used for your YouTube video, click “Save” on the video edit page.

That’s how you change thumbnails for YouTube videos. The process to change thumbnails using the YouTube Studio App on a mobile phone, no matter if it’s an Android or iPhone, is similar to what I show you here.
Thanks for reading.
See you next time.
