Upload your video
Cut unwanted parts from the beginning or end of a video with simple preview-based controls.
Hints
- Wait for the current download to finish before starting another trim job, or it may fail.

Precise start and end
Use the preview slider, Set buttons, or typed timestamps to keep only the section you want.
Private by design
Your video stays on your device while the browser prepares the trimmed download.
Practical video output
Export a shorter MP4, MOV, or MKV with the selected audio track kept when available.
Frequently asked questions
Can I trim a video online without uploading it?
Yes. The selected video is processed in your browser, so it is not uploaded to a server.
Can I choose exact start and end times?
Yes. You can type timestamps in seconds or use the preview slider with the Set buttons to pick the range.
Which input formats are supported?
This page accepts common video files including MP4, MOV, M4V, MKV, WebM, AVI, FLV, TS, and M2TS.
What happens if the video has more than one audio track?
The tool keeps the default audio track when one is marked. If not, it keeps the first audio track. Videos without audio can still be exported.
Why did my trim fail?
Very large files, unsupported video details, or a range that is too difficult for the browser can fail. Try a shorter range, a smaller file, or the desktop app for larger jobs.
