Frequently Asked Questions
How do I make an iPhone ringtone?
Upload a song and cut out a 20-second section that you like. Export it, then change the file extension on your computer to .m4r. You can then transfer it to your phone.
Is there a file size limit?
Not practically. The trimmer runs entirely inside your browser's memory. You can edit long, heavy files without waiting for slow internet uploads.
