What is this tool?

A browser-based audio editor for shortening a clip. Load a file, drag the waveform handles to the range you want, and choose whether to keep that range or remove it — no upload, no account, no software to install.

When to use it

  • Removing dead air from the start or end of a recording
  • Cutting a specific clip out of a longer podcast or lecture
  • Trimming a voice memo before sharing it
  • Cutting out an unwanted section (like a cough or interruption) from the middle of a track
  • Shortening a song intro before using it elsewhere

How to use it

  1. 1Drop in an audio file — the waveform renders automatically
  2. 2Drag the two handles on the waveform to set your start and end points
  3. 3Choose Keep (export just the selected range) or Cut (remove the selected range and keep the rest)
  4. 4Click Trim to process, then preview the result
  5. 5Download the trimmed audio as a WAV file

Frequently asked questions

Does trimming lower the audio quality?

No — the audio is decoded and re-encoded as WAV, which is lossless, so no compression artifacts are introduced.

What file formats can I upload?

Any format your browser can decode — MP3, WAV, M4A, OGG and most other common audio formats.

Is there a length limit?

No hard limit is enforced; very long files just take a little longer to decode and render.

Is my audio uploaded anywhere?

No — decoding, trimming and re-encoding all happen locally in your browser tab.
