Shorts Clipper
Drop in one long video and this tool finds its loudest, most energetic moments, then exports them as vertical 9:16 clips — entirely in your browser, never uploaded. Be clear about what it does: it measures audio energy, it does not understand what is happening in the video — but laughter, applause, big reactions and the loudest talking points are exactly where energy peaks, so it finds the moments most likely to work as Shorts. The first run loads the video engine (about 32 MB, from this site).
Got your clips? Post them all in one go with MultiHandler — one upload to TikTok, YouTube, Facebook and Instagram. Vertical clips pair naturally with burned-in captions: try the Caption Burner next.
Frequently asked questions
How does it pick the moments?
It listens to the audio only. The tool extracts the sound track, measures how loud/energetic every second is, smooths the curve, and picks the highest-energy stretches of your chosen clip length — spaced apart so the clips never overlap. Laughter, applause, raised voices and big reactions score highest. It is energy detection, not AI scene understanding, and you can nudge any start time by hand before exporting.
What if my video has no audio?
Then there is no energy to measure, so the tool says so and falls back to evenly spaced moments across the video. You can still adjust every start time yourself and export the clips.
Is my video uploaded anywhere?
No. Everything — the analysis and the exports — runs 100% in your browser on your own device, using a video engine loaded from this site. Your file never leaves your computer, and there is no server queue.
