Ytmp3 is a browser-based service for searching YouTube videos and converting supported videos into downloadable MP3 audio, with MP4 options available for some sources. Its interface lets users search by song title, artist, or keyword, or paste a video link directly. Search results and trending suggestions help users compare recordings before opening the converter and reviewing the formats offered.

The service is designed for straightforward use on desktop and mobile browsers, with light and dark display modes and optional clipboard access for pasting links. No separate desktop converter is required. Ytmp3 also provides practical guidance through its frequently asked questions and blog, covering audio quality, bitrate, file formats, downloads, troubleshooting, and online safety.

Available formats and quality depend on the source and conversion provider. The site advises users to download only material they own, have permission to save, or are otherwise authorized to use, and notes that public access does not itself grant copying rights
