To protect your channel from COPPA, you can download all videos in the channel to your computer for backup or re-upload them to other platforms. Since online websites do not support batch downloading of videos, and most of them have suspicious and unsafe ads embedded, thus, it is better to use a safe and reliable tool like Jihosoft 4K Video Downloader.
The last thing that I'll add is that the build quality of the software is excellent... any if you that have purchased Abbas' products in the past then you know that the quality of his software, and his customer support, are exceptional. I can’t imagine uploading all my videos all over again since I have over 500 videos in one of my accounts. I really needed this software!!
