Video thumbnails let viewers see a quick snapshot of your video as they're browsing YouTube. After your video is finished uploading, you can choose a thumbnail from the three options YouTube automatically generates, or upload your own if your account is verified.
You can also add thumbnails in the YouTube Studio app on your mobile device.

Custom thumbnail best practices
Image size & resolution
Your custom thumbnail image should be as large as possible. It will be used as the preview image in the embedded player. We recommend your custom thumbnails:
- Have a resolution of 1280x720 (with minimum width of 640 pixels).
- Be uploaded in image formats such as JPG, GIF, or PNG.
- Remain under the 2MB limit.
- Try to use a 16:9 aspect ratio as it's the most used in YouTube players and previews.
Thumbnail policies
- Nudity or sexually provocative content
- Hate Speech
- Violence
- Harmful or dangerous content
