Audio Silence Remover
Cut the dead air from the start and end of an audio file right in your browser. Drop in a recording and the tool finds where the sound actually begins and ends, then trims the quiet edges while keeping a little padding so nothing gets clipped. Adjust the silence threshold in dBFS and the padding in milliseconds, then download a tidy WAV. The audio never leaves your device.
How to remove silence from audio
- Drop an audio file in, or click to browse.
- Adjust the silence threshold and the padding kept on each side.
- Click Download to save the trimmed WAV file.

Frequently asked questions
Is my audio uploaded anywhere?
No. The file is decoded and trimmed entirely in your browser. Nothing is uploaded to any server, so it works offline once the page has loaded.
What does the threshold do?
It sets how quiet a part has to be to count as silence, measured in dBFS. A higher value like -40 dBFS trims more aggressively; a lower value like -60 dBFS only trims near-total silence.
Why does it keep a little audio at the edges?
The padding setting keeps a few milliseconds of lead-in and tail so words and notes are not clipped off abruptly. Set padding to 0 for the tightest possible cut.
Does it remove silence in the middle too?
No. This tool trims only the leading and trailing silence, so the timing of the audio in between is preserved exactly.
What format is the download?
A 16-bit PCM WAV file at the original sample rate. WAV is uncompressed and plays everywhere, so trimming does not lose quality.
