What Is Video Cutter?
Video Cutter is a browser-based video trimming tool that lets you cut videos without uploading them to any server. Using FFmpeg.wasm — a WebAssembly port of FFmpeg — all processing happens locally on your device. This means your videos stay private, processing is fast, and there are no file size limits beyond what your browser can handle.

Frequently Asked Questions

No hard limit. Files up to 2GB work well; larger files depend on your device's RAM.
Why is processing slow?
Video processing is CPU-intensive. Speed depends on your device, video resolution, and duration.
Can I cut videos offline?
