HitPaw does not recommend that users use watermark-free TikTok videos for anything other than personal use. If you really want to, you need to notify the video owner first. If you can't reach the original TikTok video maker, you can indicate the source of the cropped video in the description. Then, you can then post those videos on TikTok. However, if you are the original creator, you can publish your videos on any platform.
