About The Audio Trimmer & Cutter

Slice your MP3, WAV, or OGG files instantly without losing any sound quality.

This tool uses FFmpeg WebAssembly to execute a direct 'stream copy' (-c copy) on your local device. Because it doesn't re-encode the audio, the trimming happens instantly and the original audio fidelity is perfectly preserved!

How to Use

  1. Upload an audio file.
  2. Use the built-in audio player to find the exact moments you want to start and stop.
  3. Click the 📍 pin button next to 'Start Time' and 'End Time' to automatically copy the player's timestamp down to the millisecond.
  4. Click Trim Audio and download your new file instantly.

Frequently Asked Questions

Is there any quality loss when trimming?

No. This tool does not re-encode your audio. It slices the binary stream directly, meaning the exported file retains 100% of the original audio quality.

Are my files private?

Yes. This tool runs the industry-standard FFmpeg engine directly inside your web browser. Your files never leave your device.
