Video Trim cuts video directly in your browser. Choose a file, set where the clip should start and end, and export. Your video is never uploaded, because the trimming happens on your own device.
Nothing leaves your computer
Most free video cutters online work by sending your file to a server. You wait for the upload, wait in a queue, then download the result. For a short clip that is slow; for anything private it is worse. A video might be a family recording, a medical appointment, unreleased work, or footage covered by an agreement you signed. Uploading it means trusting a company’s retention policy, staff access controls and security practices, none of which you can inspect.
This tool takes a different approach. It runs FFmpeg compiled to WebAssembly, which means the video engine used by most desktop editing software runs inside your browser tab, using your own processor and memory. The file is read from your disk, processed locally, and handed back to you.
You can check this claim rather than take it on trust. Open your browser’s developer tools, switch to the Network tab, and trim something. You will see the page load and then nothing further. You can also disconnect from the internet once the page has loaded and keep working.
How to trim a video
Drag your file onto the page or select it from your device. The video loads immediately, with no upload wait.
Set your start and end points on the timeline. You can play the section back before committing, which makes it straightforward to remove silence at the beginning of a recording, cut out a mistake in the middle, or pull one good moment out of a long take.
Export, and the trimmed file is saved to your device.
Speed and file size
Because there is no upload or download, the slowest part of a typical online trim disappears entirely. A large file that would take several minutes to transfer both ways is ready to edit the moment you select it.
There is no file size limit imposed by us, since we are not paying to process your video. The practical ceiling is your device’s available memory, which on a modern laptop handles large 4K files comfortably. Very long recordings can exhaust that, and phones have lower limits than computers.
The honest trade-off is that your device does the work. On older hardware a long export takes longer than a well-provisioned server would need. For ordinary trimming, the time saved on transfer more than covers it.
Formats
The tool handles the formats you are likely to have: MP4, MOV, WebM and MKV, with H.264, H.265, VP9 and AV1 video inside them. That covers phone recordings, screen captures, camera footage and files downloaded from most sources.
If you are unsure which format to export for a particular destination, our guides to containers and codecs explain the differences.
No account, no watermark
There is no sign-up, no trial, no watermark on your exports, and no paid tier holding back the useful settings. You can use it as often as you like.
The site is supported by advertising, which is what keeps it free without an account or subscription. Ads are served on the page around the tool. They never have access to your video, because your video never leaves your device.
What it is for
Trimming, and doing that one job well. Cutting a highlight from a long recording, shortening a clip for a social post, removing dead air from a screen capture, or getting a file under a size limit before sending it.
It is not a full editing suite, and does not try to be. If you need multi-track timelines, colour grading or effects, use dedicated software. If you need to cut a video and get on with your day, this will be faster than anything that requires an upload.
