What is a YouTube thumbnail downloader?

Video link in, thumbnail image out.

A YouTube thumbnail downloader reads the video ID from a YouTube link and fetches the thumbnail images YouTube stores for it. YouTube keeps up to five sizes per video. With Jupitrr's YouTube Thumbnail Downloader, paste the link, see which sizes exist, and save the one you choose as a JPG.

Frequently asked questions

Is the YouTube thumbnail downloader free?

Yes. It is part of the Jupitrr Free Video Toolkit. No account, no watermark, no limit on how many thumbnails you save.

Which sizes can I download?

YouTube stores up to five sizes per video: 1280 x 720, 640 x 480, 480 x 360, 320 x 180, and 120 x 90. The tool checks which ones exist for your video and lists them. Older or low resolution uploads often do not have the 1280 x 720 version.

Which links work?

Standard watch links, youtu.be short links, Shorts, embed and live links, and a bare 11 character video ID all work. Playlist links need the video link itself.

Can I download thumbnails from any channel?

The tool fetches whatever YouTube makes public. Thumbnails belong to the creators who made them, so use it for your own videos or with permission from the owner.

Why does the file save through jupitrr.com?

Browsers block saving images from another site directly. The download passes through a small proxy on jupitrr.com so it lands in your downloads folder instead of opening a new tab. The proxy only passes the image through and does not keep a copy.

Can it write the title and description too?

Not this tool. For a title, description, and hashtags, use the YouTube Shorts Caption Generator.
