Step 3: Choose your targeted video format from the top right corner. There are a lot of formats available. Including MP4, AVI, MKV, and MOV. After this, click on the conversion icon on the right of the chosen file. If you have to convert all the videos in the chosen list, simply choose the “Convert All” option on the bottom right of the main window.
It may take some time depending on the number of files you have and the total size. You can use the "Email me when done" option to get notified once the archival completes. You can then download the created archive locally. Make sure to download it to your Google Drive shared folder or copy it there after download so it gets synced and backed up in the cloud.
Depending on how many videos you have in your channel and what your video quality is like that you uploaded and everything, this could be a really large file. So give it a lot of time to prepare and then to download. And make sure you have plenty of disk space on your computer to save all of that if it is a really large file. If I went through this too fast or you want to have more detailed instructions, I’ll put a link in the description below this video that will take you through a step-by-step walk through details of how to download and archive your entire YouTube channel, if you want to back it up and save for later.
