How to trim a video online
Choose a local video, set the start and end handles, and click Apply. The workspace shows Original length, Start, End, and Trimmed length as you adjust the range. Select Fast (recommended) or Original quality before the tool creates a separate clip for preview and download.
How to cut a video to a selected time range
- Drop a video here, or click browse files to choose a video file.
- Drag the two handles below the preview. Check Original length, Start, End, and Trimmed length as you set the range.
- Choose Fast (recommended) or Original quality, then click Apply.
- Play the result in the preview and click Download trimmed video.
What the trim quality options change
Fast (recommended) uses stream copying and is described as having no visible quality loss. When the input name has an extension, the result uses that extension. Original quality re-encodes toward the source quality, may take longer, and creates an MP4 result with H.264 video and AAC audio.
Input: clip.mp4, 00:05 to 00:30
Output: clip-trimmed.mp4, selected rangeClick Apply to start processing. During the first processing run, the page can show "Loading video engine (~30 MB, one-time download)...". A changed time range or quality choice becomes the next selection to apply.
Trim a video without changing the source
The file picker accepts video files, and the drop area lists MP4, WebM, MOV, AVI, MKV, and more. The source opens in the browser, and a new result is prepared for preview and download. The original file stays unchanged.
The browser must recognize the selected file as a video. An invalid selection shows "Please choose a video file." If the video engine is unavailable, the page reports that error. The page does not state a maximum file size or exact browser support.
Check the selected range before downloading
Use the preview to check where the clip begins and ends. The Start and End values show the two points, while Trimmed length shows the duration of the selected section. Leave more than 0.05 seconds between the handles, or Apply will not start the trim.
Fast uses the stream-copy path. If you need the other processing path, select Original quality, click Apply, and wait while the browser video engine re-encodes the clip.
Trim a clip or make a broader video edit
Use Video Edit Tools when you need to select a start and end point. Choose Video Editor when the edit also needs crop, resize, rotate, flip, aspect-ratio reframe, audio, playback, color, codec, or quality controls. Choose Video Subtitle Burner to permanently burn SRT or WebVTT subtitles into a local video.
