Hi, I know how to help you, I've been using the SaveTikTok site myself for a while now and I'd like to recommend it to you. On it you can download videos from TikTok free of charge and without restrictions, without watermarks and in good quality. You can also download music. You just need to paste the link to the video and you will get the finished file. Here is the link to https://savetiktok.org. Hope I was able to help you, have a nice day)
