Cut a time interval from a video in your browser. Choose stream copying for a fast cut or re-encoding for a more precise cut.
Ready.
How to use
Select a video and use the preview to choose start and end times. Choose a trim method, wait for processing, check the preview and download. The video engine downloads on first use.
Limits and compatibility
Fast cuts can shift to nearby keyframes and depend on codec/container compatibility. Precise cuts re-encode as H.264 MP4 and can alter quality. Large files require substantial memory; some formats cannot be previewed by your browser.
The tool processes selected files in this browser. Download the result before closing the tab.
Quick answers
To cut a video from 5 to 10 seconds, enter 5 as the start and 10 as the end, then select a trim method. Precise trim re-encodes to H.264 MP4; fast trim copies compatible streams and can start near a keyframe.
Questions and troubleshooting
Which trim method should I choose?
Use fast trim when speed and avoiding re-encoding matter; check the cut because boundaries may shift. Use precise trim for closer timing, allowing more processing time and possible quality changes. Always preview the downloaded clip.
Why does loading take time or processing fail?
The FFmpeg engine downloads from this site on first use; the video processing itself runs in the browser. Large files consume memory and not every codec can be previewed or copied. Try a shorter input or precise trim when fast copy fails.
What we checked
Both trim modes created MP4 output from a generated clip. The precise output lasted one second, including a repeat test on the published Spanish page. Checked October 1, 2026 in Chromium.
