What is Video Trimmer?
Video Trimmer cuts unwanted intro, outro, or middle sections from video recordings. Use visual timeline handles or type exact millisecond start and end timestamps to export trimmed clips directly within your browser.
Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.
