Remove Silence from Video
Automatically detect and cut silent gaps from a video, free and processed entirely in your browser.
About Remove Silence from Video
Dead air, long pauses, and silent gaps make a video feel slower than it needs to — cutting them out by hand means scrubbing through the whole timeline looking for quiet spots. This tool finds them automatically by analyzing the audio track, and cuts them out in one pass.
Adjust the silence threshold and minimum gap length to match your footage — a noisy recording and a quiet studio mic need different settings. A small buffer is kept around every cut so speech doesn't sound clipped. Everything runs locally in your browser using the Web Audio and MediaRecorder APIs; your video is never uploaded to a server.

Frequently Asked Questions
How does this tell silence apart from quiet speech?
It measures loudness in small time windows and flags any stretch below your chosen threshold that lasts longer than your minimum gap length — short natural pauses between words are left alone.
Will cuts sound abrupt or clip my next sentence?
No — a small buffer is automatically kept around every cut point.
What if the defaults don't work well for my recording?
Adjust the threshold and minimum gap length — the defaults are a starting point, not a fixed rule.
Is my video uploaded anywhere?
No. Detection and re-encoding both happen entirely in your browser.
