YouTube thumbnail is the video cover image that gives a preview of the video. There are two types of YouTube thumbnail: automatically generated by YouTube, and uploaded by the creator. Thumbnails uploaded by creators are also called custom thumbnails. No matter what kind of thumbnail, its URL is hidden, you can't find the thumbnail link on YouTube, and you can't save it.

A YouTube video can have up to nine thumbnails, but not every video has nine thumbnails. There are seven thumbnails guaranteed to exist:

• Player Background 480x360
• Start 120x90
• Middle 120x90
• End 120x90
• High-Quality 480x360
• Medium Quality 320x180
• Normal Quality 120x90

Besides, if the video is high-definition, there will be two other sizes of the thumbnail.

• Standard Definition 640x480
• Maximum Resolution 1920x1080

But the most commonly used sizes are High-Quality, Medium Quality, and full size. Therefore, the YT Youtube thumbnail downloader only provides downloads in these three sizes. If you need other sizes, I'll tell you how to get it later.

YouTube video thumbnails are one of the most important metadata of a video, and attentive creators will carefully design the video cover. That has resulted in most of the video covers on YouTube being beautiful, either funny or creative. It makes many people want to download and save. In general, based on the following purposes:

1. Save YouTube thumbnail as wallpaper.

The YouTube video ID is a unique ID used to identify the video uploaded to YouTube. Youtube video ID is used to create a unique URL for displaying videos and can be used to embed Youtube videos on any website.

The video id is usually at the end of the video URL, such as the following two video links:

• https://www.youtube.com/watch?v=dy6Hj0Kk-CA
• https://youtu.be/dy6Hj0Kk-CA

The character dy6Hj0Kk-CA is the video ID. Below is a list of all nine thumbnail image links of a video, replace the video id with your own to get the video thumbnails.

The copyright of the thumbnail belongs to the creator or designer. Without the permission of the copyright owner, they can report and sue you for using the content in the thumbnail. Therefore, I don't recommend copying the video thumbnails of others. But it can be used as a design inspiration to create your thumbnails.
