YouTube MP3 and MP4 Downloader has a search feature so you can locate anything you might be looking for, showing you the same results as if you were doing the search directly on YouTube itself. Once you see the results of your search, just click on the file you want to download. You can also preview it to make sure it's the right one.
When you want to download a file directly to the memory of your Android, you have to select MP3 or MP4 depending on how you want the file, and after a few seconds' wait for the video to process, the download will begin. While you wait, you can continue browsing the platform to add other files to the queue.
Once the process is finished, you can locate the file in the output folder you selected, which can also be changed whenever you like. Although the sound is usually of a lower quality than the original, YouTube MP3 and MP4 Downloader offers good quality overall.
