Is my video sent to a server?

No. All processing happens 100% in your browser using FFmpeg.wasm (WebAssembly). Videos never leave your device.

What video formats are supported?

MP4, MOV, and WebM files up to 100MB. MP4 is recommended for best compatibility.

It depends on video length and your device. A 1-minute trim typically takes 10-30 seconds on modern hardware.

We use FFmpeg's 2-pass palette generation for the best color quality. You can control FPS and output width for optimal file size.

Video processing is resource-intensive and works best on desktop. Mobile devices may experience slower processing or memory limitations.
