How it works

Three quick steps. No sign-up. Nothing leaves your device.

  1. 1

    Add your music

    Drop in one song or many. They sit on your own phone or computer the whole time.

  2. 2

    Pick the format you want

    Choose what to turn it into — MP3, FLAC, WAV, and more. We pick smart defaults so you can just hit go.

  3. 3

    Save

    Save the new files one at a time, or grab them all in a single zip.

What you can do here

More than just a converter — also a clip trimmer, a looper, and an iPhone ringtone maker.

  • Convert between formats

    MP3, FLAC, WAV, OGG, M4A, AAC, Opus, AIFF, and Apple Lossless. Pick a quality preset; we set the right encoder for you.

  • Trim and cut

    Drag the edges of the clip to trim the start or end. Click the Cut tool and tap the timeline to remove sections in the middle. The rest joins seamlessly.

  • Loop a section

    Like a chorus or a short loop? Set Repeat to 2, 5, or up to 100. The kept part plays back-to-back in the saved file.

  • Make an iPhone ringtone

    Trim the part you want (under 30 seconds), then click "Make iPhone ringtone". You get a .m4r file ready to drop into Settings > Sounds.
