MP3 cutter & ringtone maker

Select a start and end to keep or remove a clip. Fade in/out and a ringtone preset. Everything runs in your browser, your file never leaves your device.

How Audio cutter works

Audio Cutter lets you trim a precise segment from an MP3, WAV, M4A, AAC, OGG or FLAC file right in your browser, with no sign-up and no file ever sent to a server. Pick a start time and an end time, then either keep that selection (with optional fade-in and fade-out) or remove it and stitch the remaining parts back together. A one-click ringtone preset grabs the first 30 seconds with a clean 2-second fade-out.

The cut is handled by ffmpeg compiled to WebAssembly, running entirely on your device. The selected range is re-encoded through the atrim filter, so the edit point is sample-accurate. Keep mode returns just your clip; Remove mode glues the two remaining fragments, so you can cut out a repeated intro, a glitch, or an unwanted section from anywhere in the file.

How to use Audio cutter, step by step

  1. Drop or select your audio file (MP3, WAV, M4A, AAC, OGG, FLAC).
  2. Set the start and end times using the sliders or by typing values directly.
  3. Choose Keep (save the selection) or Remove (delete the selection and join what remains).
  4. Optionally enable Fade In or Fade Out to smooth the cut edges.
  5. Click Cut. ffmpeg processes the file locally; your browser downloads the result.

Common use cases

  • Cutting a 30-second ringtone from a favorite song, without uploading it to any streaming or conversion service.
  • Removing a long silence or repeated intro from a podcast episode before sharing it.
  • Extracting a single verse or chorus from a track for use in a video or presentation.
  • Trimming raw voice-memo recordings to remove fumbled starts and trailing silence.

Frequently asked questions

Does my audio file get uploaded anywhere?

No. ffmpeg compiled to WebAssembly does all the work inside this browser tab. Your file is read into memory on your own device, the atrim filter runs there, and the cut result is offered as a local download. You can open your browser DevTools, switch to the Network tab, start the cut, and watch: not a single request will carry your audio data.

How do I make a ringtone?

Load your song, click the Ringtone preset button (it selects the first 30 seconds with a 2-second fade-out automatically), then adjust the start/end if you want a different section. Click Cut and download. The output keeps your original format.

What is the difference between Keep and Remove?

Keep produces only the segment between your start and end times. Remove deletes that segment and stitches the remaining parts together, so you can cut out an ad break, a gap, or a mistake from the middle of a recording.

Will cutting re-compress my audio and reduce quality?

Cutting re-encodes the selected range so the edit point is accurate and fades are applied cleanly. Quality loss in a single pass is minimal. For a lossless output, start from a WAV or FLAC source.

Can I use it without an internet connection?

Mostly. The cut itself always runs on your device, your audio never leaves your machine. The one caveat is that the ffmpeg engine is a sizeable download fetched from this site the first time you cut a file; once that download and the page have both completed, you can switch to airplane mode and the cutter keeps working with no network connection at all.

Is there a cost or file size limit?

The tool is free and asks for no account. There is no server-imposed size limit; the practical ceiling is the memory available in your browser tab. Files of several hundred megabytes cut without issue on a modern machine.

Does the ringtone or clip get a watermark or a spoken ad in it?

No. Some ringtone-maker apps and sites insert a spoken tag or a tone at the start or end of the free output. This tool never adds anything: the exported file is exactly the audio range you selected, nothing appended.

Can I cut a ringtone from a song directly on my phone?

Yes. ffmpeg.wasm runs the same way in mobile Chrome or Safari as on a computer, so you can load a song, set the ringtone preset and download the trimmed file from your phone. Setting it as your actual ringtone still requires your phone's own settings app, since that step is outside what a web page can do.
