Acceptance of these terms

By using YT1s, you agree to these terms and conditions. If you do not agree with them, please do not use the website.

The service

YT1s is a free online tool that lets you save YouTube videos as MP4 video files or as MP3 audio files. You paste a video link, choose a format and a quality, and download the file in your browser. No account is needed.

Personal use and copyright

The service is for personal, non-commercial use only. You are responsible for what you download. Only save videos that you own, that are free to use, or that you have permission to save, and always respect copyright law and YouTube's terms of service.

Things you must not do

When you use YT1s, you agree not to:

  • use the service to break any law or to download illegal content;
  • copy, scrape or call the service automatically with bots, scripts or other tools;
  • try to overload, disrupt or break the website or the systems behind it;
  • resell the service or present it as your own.

Limits of the service

Video files are available from 144p up to 1080p, and audio as MP3 at 320, 256 or 128 kbps. Only public videos can be saved, and the qualities you see depend on the original video.

We may change, pause or stop parts of the service at any time, and it may sometimes be slow or unavailable.

Third-party services

To find your download links, YT1s works with a third-party service, and thumbnails are shown from YouTube's image servers. We are not responsible for the content of the videos you save or for services that we do not control.

No affiliation

YT1s is not affiliated with, endorsed by or connected to YouTube or Google. YouTube is a trademark of Google LLC.

No warranty

The service is provided "as is" and "as available", without warranties of any kind. We do not promise that it will always work, that it will be free of errors or that it will meet your needs.

Limitation of liability

To the fullest extent allowed by law, YT1s is not liable for any direct or indirect loss or damage that results from using the service, from not being able to use it, or from files you download.
