Online Silence Remover

%25 / %65 / %10no server needed WAV by default

Remove silence from any audio file — right in your browser

Online Silence Remover finds the quiet parts of a recording, cuts the middle of every pause and gives you back a tighter file. Nothing is uploaded: the analysis and the encoding both happen inside your browser, so the audio never leaves your computer. That makes it safe for interviews, voice notes, lectures, music practice takes or anything you would rather not send to a server.

How to trim silence in three steps

  1. Choose a file — MP3, WAV, FLAC, OGG or M4A, up to 150 MB.
  2. Analyse — the waveform marks silence in blue and, in split mode, the part that will be cut in red.
  3. Trim & download — save as MP3 (128–320 kbps) or WAV 16/24-bit, with an optional crossfade so the cuts do not click.

What is split mode?

A pause in speech is not empty space — it has the tail of the previous word, a dead middle and the breath before the next word. Cutting the whole gap makes a voice sound rushed and robotic. The default 25 / 65 / 10 split keeps a quarter of the gap, deletes the middle 65% and leaves a short breath, the same trick editors use to tighten a podcast. Presets for 50 / 50, three equal parts and “cut all silence” are one click away, and you can select any range on the waveform to build your own cut list.

Made for long recordings

Every detected silence appears in a table with its start, end and length. You can disable a single cut (A/B), delete them all, copy the list or export it as CSV, JSON or Markdown — useful when you want to tighten the audio in another editor but let this tool find the pauses for you.

Frequently asked questions

Is my audio file uploaded to a server?

No. The file is decoded, analysed and re-encoded inside your browser with the Web Audio API. Nothing is sent anywhere, so the tool keeps working even if you disconnect from the internet after the page has loaded.

Which audio formats are supported?

You can open MP3, WAV, FLAC, OGG and M4A files (up to 150 MB). The result can be saved as MP3 at 128–320 kbps or as WAV 16-bit / 24-bit.

Can I remove silence between words in a podcast or interview?

Yes. Lower the minimum silence value to catch short gaps, and raise the threshold if quiet background noise is being treated as speech. Split mode keeps a small breath at each end of the gap so the speech does not sound rushed.

Is the silence remover free?

Yes. There is no account, no watermark and no server limit — the only practical limit is your device's memory (150 MB is the default maximum file size).

Does it work on a phone?

It runs in modern mobile browsers, but very long files are better handled on a desktop computer because all processing happens on your device.
