Free YouTube to MP3 Converter
YT1s lets you extract the audio from any YouTube video and save it as an MP3 file. This is useful for downloading music, podcasts, interviews, or lecture audio without needing the video portion. Paste the YouTube link into the search box, choose your preferred bitrate, and the MP3 file downloads directly to your device.
The converter works entirely in your browser, so there's nothing to install on your computer or phone. It's compatible with Android, iPhone, tablets, and desktop computers, and works across Chrome, Firefox, Safari, and Edge without any extensions or plugins.
MP3 output is available at 64kbps, 96kbps, 128kbps, 192kbps, 256kbps, and 320kbps. Lower bitrates create smaller files that are fine for casual listening, while 320kbps gives you audio quality closer to the original. If you decide you want the video instead, the same link can be converted to MP4, 3GP, WMA, WEBM, or M4A.
