How to convert youtube to m4a so I can use them on my iphone?

I’ve tinkered around with converting YouTube videos to M4A on my iPhone before, and honestly, I’ve run into a few frustrating fails. My failed experiences mainly boiled down to apps or online tools breaking, quality issues, or legal/technical restrictions on iOS. If you want a smoother experience, I’d recommend doing conversions on a computer and then transferring files to your iPhone, rather than trying to do everything directly on the device.

Honestly, iOS is pretty locked down compared to desktop. Apple’s restrictions on file access, app permissions, and browser limitations make it tricky to do seamless conversions without jailbreak or complex workarounds. Plus, YouTube’s TOS frown upon downloading or converting their content, which adds to the headache. So, this causes some obstacles for you when converting YouTube to M4A format.
