I'm sure that you know that it's possible to download videos from TikTok, but every time you do that via the app, you get watermarks on the video. That's why I think it's quite convenient that there are services like Tiktok Video Downloader that can help you get a video without any watermarks, so I think it's worth giving a try. And considering the fact that there are many high-quality videos, these watermarks can be quite distracting.
