One Thumbnail is free. You can use it without an account. The site is offered as it is. A download can fail, a platform can change its page, and the site can change or close without notice.

The cover is not yours

YouTube publishes the thumbnail. The name belongs to them. One Thumbnail only fetches that public image so you can look at it. You may not upload it as your own thumbnail, sell it, or pretend you made it.

Fair use of the tool

Paste a normal YouTube link and download the thumbnail. Do not hammer the site or scrape it with a bot.

The writing

The articles are opinion and explanation, not a promise that a cover, a title, or a test will get views. You are responsible for what you publish on your own channel.

Privacy

How links and browser storage are handled is on the privacy page. Questions go to the contact page.
