How to Trim Audio Online – Free Audio Trimmer Guide

Free online audio trimmer: select start and end times to keep the desired part of your audio file. Perfect for cutting silence, removing intros/outros, or trimming mistakes from recordings. Lossless quality, supports MP3, WAV, AAC, FLAC, OGG and more.

How Does Audio Trimming Work?

Trimming means discarding the beginning or end of an audio file, keeping only the selected middle part. Our tool uses FFmpeg's stream copy mode, so trimming is lossless: the audio is not re-encoded, preserving original quality. Just set the start and end points in seconds and the tool extracts the selected range instantly.

Step‑by‑Step to Trim Audio

  1. Upload your audio file (MP3, WAV, AAC, etc.).
  2. Wait for the file to load – its duration is shown automatically.
  3. Enter the start time (in seconds) where you want the trimmed file to begin.
  4. Enter the end time where the trimmed file should finish.
  5. Click 'Trim Audio' – the tool extracts the selected segment and provides a download link.

Frequently Asked Questions

1. Does trimming reduce quality?
No, because we do not re-encode. The trimming is done by copying the bytes of the selected range, so quality remains identical.
2. Can I trim multiple parts at once?
This tool trims a single continuous segment. For multiple cuts, use the 'Split' tool.
3. What formats are supported?
Almost all common audio formats: MP3, WAV, AAC, FLAC, OGG, Opus, M4A, AC3, AIFF, AU, etc.
4. Is my audio uploaded to a server?
No. All processing happens in your browser using FFmpeg.wasm. Your files stay private.
5. How precise can I set start/end times?
You can enter times with one decimal place (e.g., 12.5 seconds). For more precise cutting, use the preview to find exact points.
