How this video splitter works
Splitting a video means cutting it at one or more points and saving each piece as its own file. The first part runs from the start to the first cut, and each later part runs from one cut to the next. The original file is not changed, and every part is offered for download.
Each part is re-encoded to an MP4 with H.264 video and AAC sound, so a cut can land on any moment, not only on a keyframe. The work runs on WebAssembly (ffmpeg.wasm) in your browser, so the file never leaves your device. A long clip takes longer because each part is encoded. A progress bar shows the work, and each finished file has its own download button.
