How it works

How to remove silence, free, in three steps.

  1. 1

    Drop in your video or audio

    MP4, MOV, WebM, MP3, WAV or M4A, from a phone, a camera, a screen recorder or a podcast mic. It opens in your browser; nothing is uploaded.

  2. 2

    Check the cuts

    Every pause is found and marked on the waveform. Set how quiet counts as silence, how long a pause must be, and how much breathing room to leave. The cuts update as you move the sliders.

  3. 3

    Download the tightened file

    Get it back in the same kind of file, at full quality with no watermark. Or download the cuts as an EDL and open them in Premiere Pro or DaVinci Resolve.

Why this one

Free, with nothing held back, and nothing uploaded.

Finds the pauses for you

It listens to the whole recording and sets the threshold from its own room noise and voice level, so it works on a quiet studio mic and a noisy phone alike.

Cuts that don't click

The sound fades over 10 milliseconds into and out of every cut, and short gaps of breath are kept, so the result sounds edited, not chopped.

Full quality, no watermark

Videos come back as an MP4 at their own resolution, up to 4K, encoded at high quality. Audio comes back as the format it came in: M4A, MP3 or WAV.

Keep editing in your editor

Download the cut list as an EDL, import it into Premiere Pro or DaVinci Resolve, and the jump cuts are on your timeline, linked to your original file.

Your file is opened and processed by your own browser. It is never sent to a server, so it stays private, and there’s no upload to wait for.

Removing silence from an audio file

Long pauses make a recording feel slow: a podcast where the host thinks before every answer, a voice memo with gaps between ideas, a voice-over recorded line by line. Cutting them by hand in Audacity or GarageBand means finding each one on the waveform.

Here the waveform shows every pause the tool found, shaded, before anything is cut. Move the threshold until it catches the gaps and not your quieter words, choose how much of each pause to keep, and download. An MP3 comes back as an MP3, a WAV as a WAV and an M4A as an M4A.

Questions

The silence remover: your questions, answered.

How do I remove silence from an MP3 for free?

Drop the MP3 on this page. The pauses are found and shaded on its waveform; adjust them if you like, then press Remove silence and download the new MP3. Nothing is uploaded and there's no watermark or account.

Will the audio quality drop?

WAV stays lossless: only the pauses are taken out. MP3 and M4A are compressed formats, so the kept audio is encoded again, at a high bitrate where the difference isn't audible. If you need it untouched, convert to WAV first.

How does the silence remover decide what's silence?

It measures how loud the recording is every 10 milliseconds. Anything below the threshold for longer than the minimum pause is cut, apart from a short margin kept on each side so words don't start or end abruptly. The threshold starts a third of the way from the room's noise up to your voice, worked out from the recording itself; you can move it.

Will it cut off the start or end of my words?

Not with the default settings: 0.15 seconds of each pause is kept on either side of the speech. If you speak softly or trail off, raise the padding or lower the threshold and watch the marked cuts change before you export.

Can I use the result in Premiere Pro, DaVinci Resolve or CapCut?

Yes. The downloaded MP4 opens in any editor. For Premiere Pro and DaVinci Resolve you can also download the cuts as an EDL (edit decision list): import it and every cut is on your timeline, pointing at your original footage, so you can still adjust each one.

Does it work on music or videos with background music?

It's made for speech. With music under the voice there may be no quiet moments to find, so little or nothing is cut. Use it on the voice recording before the music is added.

Is this silence remover really free?

Yes. There's no price, no trial, no account and no limit on how many files you do. The silence remover runs on your own device, in your browser, so it costs us nothing to run and we don't charge for it.

Does it add a watermark?

No. The file you download has no watermark, no logo and no intro or outro added. It's your file, changed only in the way you asked.

Is my video or audio uploaded anywhere?

No. The file is opened and processed by your browser, on your device, and never sent to a server: not to us, not to anyone. You can check: watch the Network tab of your browser's developer tools while it works, and you'll see the file is never sent anywhere.

How big a file can it handle?

There's no file size limit of ours. Files of several gigabytes work, because the file is read from your disk as it's needed rather than loaded all at once. What sets the pace is your device: a long 4K video takes longer on an older laptop than on a new one.

Which browsers does it work in?

Current versions of Chrome, Edge and Safari, and Firefox on a computer: any browser with the WebCodecs API for encoding video and sound. Some files, like iPhone HEVC video, need Chrome, Edge or Safari to decode. A computer is much faster than a phone for long videos.
