YTMP3 is a free, browser-based service for converting YouTube videos into MP3 audio files. Users paste a video link, select a bitrate, and download the converted audio without creating an account or installing software. The service works on Windows, macOS, Android, and iPhone, and supports quality settings from 64 kbps to 320 kbps. Lower bitrates create smaller files suited to speech, while higher settings are intended for music and retain more of the source audio’s detail.

The site is designed around a simple conversion process, with a link field, a Convert button, and a download option. It says the service has no pop-ups, redirects, or conversion limits, and describes its use as free, with an optional coffee contribution to support the site. Standard YouTube videos up to four hours are supported; live streams, age-restricted videos, and longer videos are not. YTMP3 encourages users to convert content they have the right to save, such as their own uploads or material freely shared by its creators.
