How to Cut a Clip Out of a Video Without Uploading It

Here's the actual process for cutting a clip out of a video with Video trim, from choosing the file to downloading a trimmed result with its audio intact.

Step 1 - choose the video

Choose or drag in a video file, up to 600 MB - MP4, WebM, MOV, or anything else your browser can play back. A preview appears immediately using the native video player, and that's where the duration gets read from before anything heavier starts.

Step 2 - set the start and end

Two number fields, start and end, in seconds, default to the video's full length. Use the player above them to find your marks the normal way - play, pause, scrub - then set the numbers to match. A running estimate line shows how many seconds will actually be trimmed as you adjust either value, and the end time always has to land after the start.

Step 3 - trim and download

Click Trim. What happens next depends on what your browser supports, and the loading label tells you which stage is running: "Reading frame :n of :total…" while frames are captured, "Encoding your clip…" while they're compressed, then "Finalizing the file…" while everything gets packaged into the output file. On a browser without the newer encoding APIs, you'll instead see a plain message that trimming will take about as long as the clip itself - a real-time capture running in the background rather than a silent spinner pretending to be instant.

What comes out

On current Chrome, Edge and recent Safari the download is an MP4 (H.264 video, Opus audio) matching the exact range you set; on a browser that uses the real-time fallback it is a WebM file instead. If your source video had no audio track to begin with, the trimmed output is just the video stream - the tool detects that up front rather than failing on it.

If something won't trim

A video the browser can't open produces a plain message naming formats that reliably work (MP4, WebM, MOV). A trim range with the end before the start is disabled at the field level before you can even run it. And on a browser without newer video-encoding support, a trim longer than five minutes is refused up front with the reason stated plainly, rather than starting a run that would otherwise take five real minutes to fail.

Nothing leaves your device

The video you choose and the clip you download never touch a server at any point - reading, trimming, and encoding all happen inside the browser tab, on your own device.
