What the tool does, how to run it, and what to expect from the result.

How to cut an audio file

To use the Audio Cutter, load one audio file, then set the start and end time for the part you want to keep. The tool isolates that range and lets you export it as a new, shorter file without affecting the original on your device.

You can export the clip as MP3, which is the default and plays everywhere, or trim supported files back out in their original format when you want to preserve the source codec. Both options run entirely in your browser.

  • Load an M4A, MP3, WAV, AAC, or OGG file
  • Set the start and end time of the clip
  • Export as MP3 or the original format

Why this matters beyond MP3-only cutters

People often just need to cut one audio file, regardless of whether it came from a voice memo, recording app, lecture export, or messaging app. A broader cutter that accepts M4A, MP3, WAV, AAC, and OGG matches that real-world workflow better than a format-specific page alone.

Because the cut happens locally, your recording never leaves your computer. That privacy matters for interviews, voice notes, and personal audio, where uploading a file to a server is exactly what you want to avoid.

Tips

Getting a better result out of Audio Cutter

Specific settings and thresholds, not general advice.

  • The times are in milliseconds because a clean cut belongs on a silence, not on a round second. Two hundred milliseconds is often the difference between a clean start and a clipped word.
  • Cutting is the only edit that shrinks the file for free. Fewer seconds means fewer bytes, with no quality trade at all.
  • Leave 100 to 200 ms of silence at each end. A clip that starts exactly on the first syllable sounds abrupt and one that ends on the last sounds truncated.
  • Make all your cuts in one pass. Each export re-encodes the audio, so cutting an already-cut file costs quality twice.
  • If the ends click, add a short fade with the MP3 Fade In/Out tool. A cut landing mid-waveform is the usual cause.
Limits

What Audio Cutter does not do

The honest boundary, so you do not lose time finding it yourself.

  • It does not merge or join clips.
  • It does not detect silence automatically.
  • It does not fade or change the volume.
  • It exports the clip; it does not edit in place.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Can I export MP3 or keep the original format?

Yes. MP3 is the default export, and supported files can also be trimmed back out in their original format so you keep the source codec when you need it.

Which formats can I cut?

The Audio Cutter accepts M4A, MP3, WAV, AAC, and OGG files as its main inputs, covering most voice memos, recordings, and downloads.

Does the trim stay local?

Yes. The clip is cut and exported entirely in your browser. The audio file is never uploaded to a server, so your recording stays on your device.

Is the audio cutter free?

Yes. The Audio Cutter is free to use with no signup and no watermark, and it runs locally so there is no upload queue or account needed.

How do I cut a section out of an audio file?

Set the start and end in milliseconds and export. The clip between them is written out as a new file in your browser, and the original is untouched.

Which audio formats can I cut?

The common ones, including MP3, WAV, M4A, AAC and OGG. The file is decoded in your browser and the clip is exported from there.

Does cutting reduce the file size?

Yes, in proportion to what you removed, and it costs nothing in quality. It is the only edit that is free in that sense.

Why does my clip click at the start?

Because the cut landed mid-waveform. A short fade, even 100 ms, removes it: use the MP3 Fade In/Out tool afterwards.

Can I cut several sections at once?

Not in one pass here. For splitting a file into several pieces, use the MP3 Splitter, which places multiple cut points.
