Looking for a YT1s MP4 converter?
People search for this as yt1s mp4, yts1 mp4, yst1 or y1ts. Whichever spelling you used, this page does one job: turn a public YouTube link into an MP4 file you can save. yt1s.video is an independent service and is not affiliated with other sites that use a similar name.
How it differs from other YT1s sites
This site is independent. It shows no pop-up ads, asks for no extension and never asks for your Google login.
What you get
MP4 video up to 1080p, or M4A audio. It does not create MP3 files or 4K video.
Misspellings are fine
yts1, yst1, y1ts, yt 1s and yt1 all lead to the same idea: a quick YouTube downloader. You are in the right place.
If your download does not start
Check that the video is public and still available on YouTube. Try a lower quality if the selected format fails. Private, removed, live or region-restricted videos may not be supported. Current limits are 30 minutes and 500 MB per download.
Save the file before the link expires
Prepared links are temporary. If a link expires, paste the original video URL again to prepare a new one. On a phone, check your browser downloads or Files app for the saved MP4 or M4A file.
