YouTube link cleaner
Removes the si and feature parameters. Keeps the video ID, timestamp (t) and playlist (list).
What it changes
Apps append parameters to shared links that identify the share or campaign. Untail removes those and keeps the ones the page needs, like the video ID.
Keeps what the page needs
YouTube video IDs, timestamps and playlists survive. Only known tracking parameters are removed.
Expands TikTok short links
vm.tiktok.com and vt.tiktok.com links are followed once by our server to get the full video URL.
Runs in your browser
Normal links are cleaned locally and never sent anywhere. Only short links are sent to our server to resolve the redirect.
FAQ
What is the si parameter in YouTube links?
YouTube often adds ?si=... to shared youtu.be or Shorts links. It is not needed to identify the video and Untail removes it.
Does Untail keep timestamps?
Yes. Parameters such as t and start are preserved, so a link opening at a specific moment keeps working.
Does Untail preserve playlists?
Yes. It keeps list and index, along with the video ID v, so the link can still refer to the chosen playlist position.
Install as an app
Add Untail to your home screen. On Android you can then pick it from the Share menu to clean a link directly.
