Frequently Asked Questions

How do I download a YouTube thumbnail?

Paste the YouTube video URL above and click "Get Thumbnails." We'll show you all available resolutions. Click "Download" on the one you want.

What resolution thumbnails are available?

YouTube stores thumbnails in several sizes: Max Resolution (1280×720), Standard (640×480), High Quality (480×360), Medium Quality (320×180), and Default (120×90). Not all videos have the max resolution version.

Is this free to use?

Yes, completely free with no limits. No sign-up, no watermarks, no strings attached.

Can I use downloaded thumbnails?

Thumbnails are owned by the video creator. You can use them for commentary, reviews, or reference under fair use. For commercial use, check with the original creator.

Why is the max resolution thumbnail not available?

Not all YouTube videos have a 1280×720 thumbnail. This usually happens with older videos or those where the uploader didn't provide a custom thumbnail. The next best resolution (640×480) is always available.
