MP3 Cutter

RUNS ON THIS DEVICE

Cut a section out of an MP3, WAV, or M4A file without installing anything. Play the audio, mark the start and end, and export just that slice.

Trim audio without opening an editor

Most audio trims are small jobs: cutting a ringtone out of a track you own, pulling a quotable minute from a podcast episode, or removing the dead air at the start of a voice recording. Installing a desktop editor for that is overkill. This cutter loads your file into a player, lets you set precise start and end times, and exports just that slice as an MP3.

Preview before you commit

Because the file is already in your browser's memory, you can scrub through it, listen to your selection, and adjust the in and out points as many times as you like. Upload-based cutters make every adjustment a round trip — re-upload, re-process, re-download — which turns a thirty-second edit into a ten-minute chore. Here, moving a marker and exporting again takes only as long as the export itself.

What goes in and what comes out

You can trim MP3, WAV, and M4A files; the exported slice is always an MP3, which plays everywhere and works directly as a notification or alarm sound on Android. iPhones are pickier about ringtones — iOS expects the .m4r format — so plan on one extra conversion step if that is your goal. Your audio is decoded and re-encoded entirely on your own computer; nothing is transmitted, stored, or logged on a server.

Frequently asked questions

Does my audio ever leave my computer?

No. The player, the trimming, and the MP3 export all run locally in the browser tab, and closing the tab removes every trace of the file.

Can I use the result as a ringtone?

On Android, yes — MP3 works directly. iPhones require the .m4r format, so you would need one extra step in GarageBand or Finder to set the clip as a ringtone.

Which audio formats can I trim?

MP3, WAV, and M4A files are accepted, and the trimmed output is saved as MP3.

Can I make several cuts from the same file?

Yes. Adjust the start and end points and export again as often as you like — there are no per-edit fees, task limits, or watermarks.
