Is YouTube to MP3 safe?

Low risk

YouTube to MP3 injects a hidden remove.video iframe into every visited page after install or update.

The extension runs a content script on all websites and, after install or update, appends a 1-pixel hidden iframe that loads remove.video/start. That request can send the visited page context, including the page URL or referrer and the user's IP address, to remove.video outside the stated YouTube conversion flow.

Where it sends data

Destinations our analysis observed YouTube to MP3 contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
