How to trim a video and save the part you need

QUICK ANSWER

Open a video, set the start and end times and choose whether to keep or remove the selection. Preview your edits, choose an output format and export a new clip.

A short clip is often easier to share than a whole recording. Video Trimmer Online lets you set exact boundaries, preview edits and add a few finishing touches before exporting a new file.

1. Open your file

Open a supported video and wait for its preview and timeline. Other supported codecs may need a compatibility preview before they play in the browser.

2. Work through the settings

  1. Drag the start and end handles or enter exact times. Choose whether to keep the marked section or remove it.
  2. Crop, rotate, mute or adjust speed only where needed. A caption or image overlay should be placed where it does not hide the subject.
  3. Render a short edited preview to check the combined changes. Original playback alone does not show every exported effect.
  4. Choose a supported output such as MP4, WebM or GIF and export. Use Precise mode for accurate cuts; Fast keyframe mode trades exact timing for speed.

3. Check before you share

  • Watch the first and last moment of the saved clip.
  • Listen for abrupt sound cuts and check any fades.
  • Check captions, crop edges and the final output dimensions.

Questions you may have

Why is a fast cut not at the exact frame I chose?

Fast mode follows keyframes for speed. Choose Precise mode when exact boundaries matter.

Can I save one frame as a picture?

A PNG frame export is available. Check the selected frame carefully before saving it.
