About the online video trimmer

Choose the section you want to keep and the tool removes everything before the start point and after the end point. The selected clip is exported as a browser-friendly MP4 with H.264 video and, when present, AAC audio.

Use the timeline to set both boundaries to a hundredth of a second, or play the video and assign the current position as the start or end. Preview the selection before processing so you can check the cut without repeatedly exporting the file.

Trimming runs locally in your browser with ffmpeg.wasm. Your video is never uploaded, there is no watermark, and no account is required. The video engine is downloaded once on first use and then kept in the browser cache.

When a video trimmer helps

Remove an unwanted beginning or ending

Cut out the moment before recording started or the extra footage after the useful part ended.

Make a short social clip

Keep one concise moment from a longer recording for a post, story, reel or group chat.

Share part of a lesson or meeting

Extract the relevant section instead of asking someone to search through the full recording.

Prepare a clip for further editing

Create a clean source segment that is easier to merge, compress, caption or add to a presentation.

Frequently asked questions

How do I trim a video online?

Add an MP4, MOV, WebM or MKV file, set the start and end of the part you want to keep, preview the selection and choose “Trim video”. Download the finished MP4 when processing is complete.

Is my video uploaded to a server?

No. Trimming happens entirely on your device with ffmpeg.wasm. The original and the trimmed result never leave your browser.

Which video formats can I trim?

The tool accepts MP4, MOV, WebM and MKV files up to 300 MB. The trimmed result is an MP4 with H.264 video for broad compatibility.

Can I choose the cut points precisely?

Yes. The controls use hundredth-of-a-second steps, and you can set either boundary from the current playback position. The actual cut aligns with the video frames available in the source.

Will the trimmed video have a watermark?

No. The downloaded video has no watermark, branding or end card, and you do not need to create an account.
