Audio Trimmer (Waveform)

Trim podcasts, calls, or music right in your browser. Load a waveform, set start/end points, preview instantly, and export to MP3 or WAV via ffmpeg.wasm.

Workflow

  • Drop an audio file to decode it locally.
  • Use sliders or numeric inputs to fine-tune the clip bounds.
  • Preview the selection with a quick in-browser play.
  • Export a clean MP3 or WAV with metadata removed.

Notes

  • Processing is fully local; no uploads leave your device.
  • Keep selections short for faster exports.
  • WAV exports are lossless; MP3 exports use LAME for speed.
