🔒 Privacy First — Your Data Never Leaves Your Device

Your privacy is our highest priority. The Video Trimmer tool processes all your files and data entirely within your web browser using modern JavaScript and WebAssembly technology.

Frequently Asked Questions

Does the Video Trimmer upload my video to a server?

No. The entire trimming and export process executes locally inside your web browser using HTML5 Media APIs. Your video never leaves your device and is not uploaded to an AllAdvanceTools server.

How does client-side video trimming work without a server?

The tool uses the browser's native MediaStream recording engine (MediaRecorder API). It plays the chosen video segment internally from the start timestamp to the end timestamp, streaming recorded media packets into a new, standalone video blob that you can download directly.

Can I set exact millisecond start and end points?

Yes. In addition to the visual timeline sliders, you can enter exact seconds or use the "Set to Current Time" buttons to capture precise frame timestamps.

What video formats can be trimmed?

You can trim any video format natively playable by your web browser, including MP4, WebM, and MOV files. Exported clips are formatted as high-compatibility browser-encoded video files.

Is there a file size limit for trimming videos?

Because trimming occurs locally on your machine, there are no artificial server upload limits. However, processing performance depends on your device's CPU and available browser memory.
