What is the safest music converter?

I'm curious, when it comes to converting music files from one format to another, what's considered the safest music converter on the market today? I've heard about several options, but I'm unsure which one prioritizes security the most, ensuring that my music files remain protected and free from malware or data breaches. Is there a specific converter that the community trusts for its robust security features and reputation for keeping user files safe?
