Upload and preview

Video Trimmer
Upload a video, move the start and end handles, preview the selected range, and download a shorter MP4 that is ready for sharing or review.
Cut intros, dead air, repeated takes, screen recordings, demos, and social drafts.
Visible range handles help catch rough starts, early endings, or private frames.
- Set exact start and end times
- Preview the selected clip before export
- Download the trimmed result as MP4
How to use Video Trimmer
Trim a video by loading the file, finding the first frame you want to keep, setting the end point, and exporting only the selected range.
- 1
Upload the video file
Choose a browser-supported video file under the page limit. After the preview loads, check the duration and make sure the right source video is open before setting trim points.
- 2
Set the start and end
Play the video, use the 5 second skip buttons for rough movement, then drag the green and red range handles or use Set Start and Set End at the exact frame area you want.
- 3
Export the shorter MP4
Replay the selected range, confirm the cut does not remove needed context, then run the trim and download the exported MP4 file for review.
Visible trim range
Green and red handles show the part that will be kept, so it is easier to avoid cutting too much or leaving unwanted footage.
Browser FFmpeg export
The tool uses browser-side FFmpeg to create an MP4 export, so the page can run without a separate video editing app.
Playback shortcuts
Play, pause, seek, and skip 5 seconds in either direction while you choose a precise cut for clips, demos, and recordings.
Local session workflow
The source preview and trim settings live in the current tab until you export, switch files, or reload the page.
MP4 download
The final download is named from the original file and saved as an MP4, which fits most upload, chat, and publishing workflows.
Video Trimmer privacy and processing
Video Trimmer works from the file loaded in your browser tab and uses local page state for the trim range. Download the result before refreshing, because the working session is not a permanent project file.
Processing Browser
Video Trimmer loads the selected file into the browser, lets you set a start and end time, then uses FFmpeg in the page to export the selected MP4 segment.
Storage Local
The working file, object URL, and trim range stay in the current browser session unless you download the result or reset the page.
Video Trimmer account access
You can trim a video without signing in, although daily operation limits can apply before the final export runs.
Before You Use Video Trimmer
Review these notes before trimming a video, especially when the file is large, private, or intended for a public channel.
Privacy
Use a clean source file when the clip includes private faces, screens, location details, student work, client footage, or internal meetings.
Watch both cut boundaries before export so an unwanted frame, spoken name, or confidential screen is not left in the shortened video.
Accuracy
Start and end points can feel different after encoding, so preview the selected range before downloading the final MP4.
For speech clips, leave a small amount of room before the first word and after the last word to avoid a harsh cut.
Compatibility
The browser must be able to load the source file as video, and very large or unusual codecs may fail or take longer to process.
If export fails, try a shorter selection, a smaller source file, or a common MP4 source before rerunning the trim.
Output
Open the downloaded MP4 before deleting the source, then confirm playback, audio sync, and the first and last seconds.
Keep the original video until the trimmed version has been uploaded or approved in the destination workflow.
Limits
Video Trimmer accepts browser-supported video files and keeps processing on the open page; files above 500 MB are blocked and long clips can take longer to export.
Guest and account limits apply to completed trims, and FFmpeg export speed depends on the video length, resolution, and device performance.
Questions about Video Trimmer
Can I trim an MP4 video online with this tool?
Yes. Upload the video, choose the start and end range, preview the cut, and download the trimmed result as an MP4.
What should I check before downloading the trimmed video?
Check the first second, the last second, audio sync, and whether the clip still has enough context for its destination.
Does Video Trimmer require an account?
No account is required for the standard page, but daily usage limits can still apply when you export a trimmed clip.
Why is my video trim taking a long time?
Large files, long selections, high resolution, and slower devices can all make browser FFmpeg export take longer. Shorter ranges usually finish faster.
