How do I set the .m4r file as my ringtone on iPhone?

You can import the .m4r file into the free GarageBand iOS app and share it as 'Ringtone', or drag and drop it into Finder/iTunes when your iPhone is connected to your computer.

What is the maximum allowed ringtone length on iPhone?

iOS limits custom ringtones to a maximum of 40 seconds (or 30 seconds for text alerts). PullDL automatically optimizes the audio output.

Are my personal songs uploaded to a remote server?

No. Conversion runs 100% locally within your browser sandbox via WebAudio. Your audio files never touch external servers.

Is MP3 to M4R completely free?

Yes. PullDL is 100% free with no hidden charges, paywalls, or limits.
