There are a few different methods for downloading TikTok videos without a watermark, but it's important to note that many of these methods may violate the terms of service for TikTok and could lead to your account being suspended. Additionally, it's important to respect the copyright of the creators whose videos you are downloading.

That being said, one way to download TikTok videos without a watermark is to use a third-party website or app that can "scrape" the video from TikTok's servers. These types of websites and apps are available online, but it is important to be careful when using them, as some may contain malware or other security risks. Another way you could download the video is by recording the video while it is playing on your screen or use a screen recording app.

It is worth mentioning that many creators on TikTok have used the watermark as a way to protect their content and give credit to the original authorship, thus it could be seen as disrespectful to download them without the watermark. Instead, you could consider using the share option on the app and post the video on your personal account, giving credit to the original creator in the caption.
