Tiktok Link Anonymizer
This (progressive) web app can be used to anonymize Tiktok share link.
By default Tiktok share links are linked to the account that created them. This app will take those links and give you a link not attached to any account.
You can install this as a progressive web app to use it more easily. If you install it though Chrome on Android you can also use it as a share target! It may also work on iPhone but I haven't tested it.
