Even if you're using a ytmp4 download tool for personal use, the safest approach is to ensure the video is not protected by copyright or to obtain permission first.
A reputable ytmp4 downloader will often provide disclaimers or guidelines for ethical usage. By respecting intellectual property rights, users can enjoy the convenience of YouTube to MP4 download tools without legal complications. Being informed and responsible goes a long way in ensuring your downloads remain both safe and lawful.
