Audio Trimmer

Trim any audio file to the exact section you need. Select a start and end point on the waveform and export losslessly when possible.

01

How to use Audio Trimmer

  1. 01Upload your audio file — we analyze its waveform and duration.
  2. 02Drag the start and end handles on the waveform, or type exact timestamps.
  3. 03We cut the selection with FFmpeg, using a lossless stream copy whenever the format allows it.
  4. 04Download your trimmed clip.

02

Quality and privacy

We use FFmpeg on the server for processing. Files are placed in isolated temporary storage and deleted automatically after one hour. When an operation can copy an existing audio stream, we identify it instead of claiming an unnecessary re-encode is lossless.

Frequently asked questions

Does trimming reduce audio quality?
When the output format matches the input, we cut on the nearest keyframe and copy the stream directly — no re-encoding, no quality loss. If you change the output format, a normal encode is required.
Can I trim a long recording, like a podcast or lecture?
Yes, use the waveform to zoom in and select the exact start and end points, even in long files.
