What is this Tool?

Audio Trimmer is a powerful, free online tool that lets you cut and trim audio files directly in your web browser. Whether you want to create a ringtone, remove intro/outro from a podcast, or extract a specific funny moment from a recording, this tool makes it incredibly easy.

Unlike most other online editors, wowfree does not upload your files to the cloud. All processing happens locally on your device using advanced Web Audio API and WebAssembly technology. This guarantees 100% privacy and lightning-fast performance, even for large files.

How to use

  1. Upload File: Drag & drop an audio file (MP3, WAV, M4A, etc.) or a video file (MP4, WEBM) into the box.
  2. Select Region: You will see a visual waveform. Drag the start and end handles to highlight the part you want to keep. You can also type exact timestamps for precision.
  3. Preview: Hit the Play button to listen to your selection.
  4. Export: Choose your preferred output format (MP3 or WAV) and click Download. Your new file is generated instantly.

Why do you need it?

  • Privacy Guaranteed: Your personal audio recordings never leave your computer. We cannot listen to them, and neither can anyone else.
  • No Size Limits: Since there's no server upload, you aren't restricted by bandwidth or file size limits common on other sites.
  • Precision Editing: The visual waveform allows you to see exactly where silence or beats occur, making it easy to cut with millisecond precision.
  • Video to Audio: Found a great song in a video? Drop the video file here, and we'll extract the audio track for you to trim and save as MP3.
