Automatically cut the silent gaps and dead air out of a recording with this free online silence remover. Upload a file, tune the detection, see how much time you saved, and download an MP3 or WAV — all in your browser, with nothing uploaded and no signup.
Unlike a simple trimmer that only cuts the start and end, this removes every silent gap throughout the audio, tightening a whole recording in one pass — perfect for podcasts, interviews, voiceovers and audiobooks.
Silence Remover
Automatically cut the silent gaps and dead air out of a recording — podcasts, voice memos, lectures, voiceovers. Upload a file, tune the detection, preview, then download an MP3 or WAV. Nothing is uploaded.
This finds every stretch quieter than the threshold that lasts longer than the minimum gap, and removes it — keeping a little audio (keep around cuts) at each edge so the result doesn’t sound clipped. Raise the threshold if quiet speech is being cut; lower it if background hiss is being kept. A tiny fade at each join prevents clicks. Great for tightening up podcasts, interviews, audiobooks and voiceovers — all on your device, nothing uploaded.
How to remove silence from audio
- Upload your recording. Drag an MP3, WAV, M4A, OGG or FLAC onto the box (up to ~50 MB). It is processed on your device — nothing is uploaded.
- Check the result. It scans instantly and shows how many gaps it removed and how much shorter the file is.
- Fine-tune. Adjust the threshold (what counts as silence), the minimum gap (only longer pauses are cut), and how much audio to keep around cuts so it doesn’t sound clipped.
- Preview and export. Press play to hear it, then download an MP3 or WAV.
The three controls, explained
- Silence threshold (dB) — anything quieter than this counts as silence. Raise it if quiet speech is being cut; lower it if background hiss is being kept.
- Minimum gap to cut — only silences longer than this are removed, so natural short pauses between words stay.
- Keep around cuts — leaves a little audio at each edge of a cut, so speech doesn’t start or stop too abruptly. A tiny fade at every join prevents clicks.
What you can use it for
- Podcasts & interviews — remove the dead air and long pauses in one pass.
- Voiceovers & narration — tighten takes before editing.
- Lectures & meetings — cut the gaps to make a long recording shorter to listen to.
- Voice memos — clean up rambling recordings quickly.

Frequently asked questions
How do I remove silence from an audio file?
Upload it here — the tool scans for silent gaps automatically and shows the result. Adjust the threshold and minimum-gap sliders if needed, then download an MP3 or WAV.
Does it remove all the gaps or just the ends?
All of them. It removes every silence longer than your minimum-gap setting throughout the recording, not just the start and end.
Will it cut natural pauses between words?
Only if you set the minimum gap very low. By default it keeps short pauses and removes the longer, dead-air gaps. Raise the minimum gap to keep more pauses.
What if quiet speech gets removed?
Lower the silence threshold (a more negative dB value) so quiet speech counts as sound. If background noise is being kept, raise it.
What formats does it export?
MP3 (192 kbps) or WAV, both made on your device.
Does it upload my audio?
No. Everything runs in your browser using the Web Audio API; your file never leaves your device.
Is it really free?
Completely — no signup, no watermark, no limits.
