The most directly identified official site in the search results is https://ytmp3.com.im/. I’d treat that as the current candidate, but YTMP3-style sites often have clones and mirror domains, so verify the exact branding and security details before using it.

Quick check

  • The result labeled “YTMP3 - YouTube to MP3 Converter and Downloader {Official}” points to ytmp3.com.im.
  • Another result points to related YTMP3 pages on different domains, which suggests there may be multiple branded or mirror sites in circulation.
  • Because of that, the safest approach is to confirm the site you open matches the official branding and uses HTTPS.

Practical note

YTMP3-type services can be used for copyrighted content, so it’s best to only download media you own or have permission to use.

Bottom line

If you want the official website, the clearest candidate from the available results is https://ytmp3.com.im/.
