The Play Store is full of 'YouTube to MP3' apps that are ad farms or worse. A web converter does the same job in your browser with zero installs, zero permissions, and zero risk.
In the YouTube app, tap Share under the video and choose 'Copy link'. Both full videos and Shorts work.
Head to our YouTube to MP3 page in Chrome and paste the link. Press Get video and wait for the quality list to appear.
Press 'MP3 Audio'. Our server extracts the soundtrack at 192kbps and sends back an MP3 named after the video. It saves into your Android Downloads folder, ready for any music player.
192kbps is the sweet spot: indistinguishable from the source for speech and great for music. Very long videos (an hour plus) take a little longer because the entire soundtrack must be converted before sending — grab a coffee.
