AceThinker Music Keeper is a versatile tool that supports downloading MP3 songs from popular music sites. That includes YouTube, Instagram, Vimeo, SoundCloud, Jamendo, Facebook, and other online streaming websites. With its copy and paste option, you can quickly download all your favorite songs from any supported website in an instant. You can have a better downloading experience that doesn’t limit you from downloading songs from different music sites.
First, you need an MP3 downloader that can download a YouTube playlist, like AceThinker Music Keeper. Then, go to the YouTube Playlist you want to download and copy its URL from the address bar. Afterward, relaunch the Music Keeper and paste it into the tool’s search bar. Once the tool analyzes the URL, it will eventually display the playlist. Next, click the “MP3” button to download the YouTube playlist or hit the “Download” button to choose the output quality first before downloading.
If you want to download MP3 songs for free, you can use several online downloaders. Still, most tools have a downloading limit and only support 128kbps. We suggest using AceThinker Music Keeper to download them in the highest quality. This tool is dedicated to helping you download MP3 songs on Windows or Mac computer. Also, downloading MP3 songs with this tool can give you the satisfaction of downloading multiple songs at the same time.
You can use an online converter that supports YouTube to WAV audio format. However, converting YouTube videos to WAV is not ideal for uploading online. Also, the WAV format consumes more storage space than the MP3 format. Still, we suggest using Music Keeper to download YouTube videos in MP3 format so that you can save them in smaller file sizes. Then, you can upload them on social media platforms like Facebook, Twitter, and more without a hassle.
Though Music Keeper doesn't support downloading YouTube to WAV directly, you can check the article about YouTube to WAV to find a working solution.
