Will this tool cut out quiet parts of music?

It’s designed for speech, not music. Music often has soft passages that aren’t true silence. Use this tool mainly for voice recordings, lectures, podcasts, or interviews.

Can I adjust how sensitive it is to silence?

Yes. You can choose between -45, -35, and -28 dB for the silence threshold. Lower numbers (-45 dB) only catch very quiet pauses, while higher numbers (-28 dB) are more aggressive.

What file types can I use?

Most common video (MP4, MOV, AVI, MKV, WebM) and audio (MP3, WAV, M4A, AAC) formats work. Output is always MP4 for video or MP3 for audio.

Does it keep video and audio in sync?

Yes. The tool processes video and audio together, so lip sync is preserved. Cuts are made to both tracks at the same spots.

How big a file can I process?

You can process files up to about 30 minutes long. Processing speed and memory use depend on your device and browser. For longer files, trim them first.

Does it work offline?

Once the page is loaded, it can run offline. All processing is local. No files or audio leave your device.

Will it remove background noise?

No. It only removes sections below your chosen volume threshold for a certain length. It doesn’t filter or suppress ongoing background noise. Try a noise reduction tool for that.

Can I undo the silence removal?

No, the tool creates a new file with the silences cut out. It doesn’t keep a record of the removed sections. Keep your original file if you might need to redo or adjust the settings.

Is the output quality the same as the original?

The tool re-encodes video to H.264 + AAC, and audio to MP3. There’s minor quality loss, but at high bitrates (video: ~2–5 Mbps, audio: 128–192 kbps), most users won’t notice.

Can I use this for phone recordings or voice notes?

Yes. It works well on voice memos, meeting recordings, or any speech file. Just watch the input length and threshold—phone mics may pick up extra background noise.

The Silence Remover tool automatically finds and cuts out silent pauses from your video or audio file. It runs entirely in your browser. You choose how quiet and how long a pause must be before it gets removed. The tool marks and cuts each silent section, leaving just the speaking or sound, with a small buffer for natural transitions. This trims wasted time from talking-head videos, podcasts, lectures, and voice notes.

How to remove silence from video or audio

Drop your video or audio file onto the box above (up to 30 minutes).
Pick your silence threshold (how quiet counts as silent) and minimum pause length.
Click Remove silence. The tool will analyze and process in two passes.
Download the new file, with silence removed and a summary of time saved.

How silence removal works

Videozify’s Silence Remover works in two steps, all in your browser. First, it uses FFmpeg’s silencedetect filter to scan your file for sections where the volume drops below your chosen threshold (for example, -45 dB, -35 dB, or -28 dB). It marks any pauses longer than your chosen minimum (from 0.3 to 2 seconds).

Next, it uses FFmpeg’s select (for video) or aselect (for audio) filters to keep only the voiced or active sections, adding a short 0.15 second padding before and after each voiced range. This avoids abrupt cuts and keeps natural speech flow.

The video is re-encoded to H.264 for video and AAC for audio. If you process an audio-only file, it is exported as MP3. No files are uploaded or stored: everything happens locally in your browser, using WebAssembly.

This approach is ideal for talking-head videos, interviews, lectures, podcasts, or voice memos—any content with speech and unwanted dead air. You get a smoother, tighter file, and the tool tells you exactly how many pauses and seconds were removed.

Silence removal is done locally in your browser, so your files stay private. See also Video trimmer and Audio trimmer.

Silence Remover scans your audio or video for quiet pauses and cuts them out, leaving only the voiced or active parts. This makes speech content tighter and more engaging.

Settings explained

Silence threshold sets how quiet a section must be to count as silence. -45 dB catches only very quiet moments, good for studio recordings with little background noise. -35 dB is a safe middle ground for most spoken recordings. -28 dB is more aggressive and may cut softer speech or background hum.

Minimum silence length controls the shortest pause that will be removed. If you set this too low (like 0.3 s), even brief hesitations or breaths may be cut, which can sound choppy. For most speech, 0.5 to 1 second is a good starting point. Longer minimums (like 1.5–2 seconds) only cut long, obvious gaps.

Padding adds 0.15 seconds before and after each kept section. This small buffer helps make cuts sound natural, so you don’t lose the start or end of a word. You can't change the padding, but it’s tuned to avoid abrupt transitions in most cases.

Tips and alternatives for silence removal

For best results, record in a quiet room and use a consistent mic distance. The tool works well even with some background noise, but strong hum or hiss may get mistaken for speech. If you notice it’s not cutting enough, try a higher threshold (like -28 dB). If it cuts too much, lower the threshold or raise the minimum silence length.

Desktop editors like Audacity (audio only) and CapCut (video) also offer silence removal. Audacity lets you tune silence detection more precisely and preview cuts, but only works for audio. CapCut’s desktop app can auto-cut silence from video, but requires installation and exports with its own settings. VLC and Windows Photos don’t offer silence removal, though you can trim manually.

On Mac, iMovie doesn’t have automatic silence removal, but you can split clips and delete silent parts yourself. On Windows, Clipchamp lets you split and trim, but not auto-detect silence. For podcasts, dedicated audio editors give more control, but Videozify is much faster for quick jobs.

If your video is longer than 30 minutes, split it into parts first using the video trimmer or audio trimmer. For cases where you want to manually fine-tune every cut, a desktop editor is better. But for most talking-heads, lectures, or quick voice notes, this tool saves time and hassle.
