Can't download videos from TikTok

I've got some TikTok videos I like, but I don't understand how to download them at all. Can you help a newbie? Because I just registered there recently. 

As far as I know, the video can be downloaded through the TikTok application itself, but there will be all sorts of watermarks and if you post it somewhere, there may be problems with copyrights. That's why I download videos through this site https://qload.info There is absolutely nothing to pay or register, just paste the link to the video you like and click the Download button. The site itself removes all unnecessary icons.
