About MP3 Cutter
Cut audio with a real waveform
Seeing the waveform makes it easy to find the exact moment a beat drops, a word starts, or a chorus begins. Drag the start and end handles to select your region, or type precise HH:MM:SS.ms timecodes for frame-accurate cuts. Hit play to preview just the selected part before you export.
Fades and format options
Add a one-second fade-in and fade-out so your clip starts and ends smoothly instead of cutting off abruptly — perfect for ringtones and loops. Export to MP3 for universal compatibility, WAV for lossless quality, or M4A, which is the format iPhones want for custom ringtones. When you're just trimming without fades and keeping the same format, the cut is lossless.
Fast, free, and handles big files
The heavy lifting runs on our conversion server with FFmpeg, so even large lossless files process quickly. Files are encrypted in transit and automatically deleted after about an hour. No account, no watermark, no limit on how many clips you make.

Frequently Asked Questions
How do I make an iPhone ringtone?
Cut your clip to 30 seconds or less (iPhone ringtones are capped at 30 seconds), export as M4A, then rename the file extension from .m4a to .m4r on your computer. In older workflows you'd add it to your library and sync via Finder/iTunes, then set it under Settings → Sounds & Haptics → Ringtone. Android is simpler — just set any MP3 as your ringtone directly.
Will trimming reduce the audio quality?
If you keep the same format and don't add fades, the cut is a lossless stream copy — identical quality to the original. Adding fades or changing format re-encodes the audio; at the bitrates used here the difference is inaudible for normal listening.
What audio formats can I upload?
MP3, WAV, M4A, AAC, OGG, FLAC, and OPUS, up to 1GB each.
Can I use this as a ringtone maker?
Yes — select up to a 30-second region, add a fade-out, and export as M4A for iPhone or MP3 for Android. That's a ready-to-use ringtone.
Is there a length or file-size limit?
You can upload files up to 1GB and cut a clip of any length within the track. There's no cap on the number of clips you can make, and it's completely free.
