About this tool
Finds silent stretches automatically and cuts those sections out, trimming long gaps between speech and setup time. Files never leave the browser.
When to use it
- —Cutting long silences from a video where you talk to camera alone
- —Reducing dead time spent waiting during a screen recording
- —Tightening a lecture video so it takes less time to watch
Good to know
- —A high silence threshold also cuts quietly spoken parts; always review the result.
- —Because cuts follow the audio, the picture can jump abruptly; it suits talking footage more than visually continuous shots.
- —Videos with constant background noise make silence hard to detect.
