About LosslessCut
LosslessCut is a cross platform desktop application for lossless editing of video, audio, and subtitle files. Built with Electron and TypeScript, it serves as a graphical interface to FFmpeg, enabling users to perform precise cuts, trims, merges, and track manipulations without re encoding, thus preserving original quality. It targets users who need to rapidly process media files—such as raw footage from cameras, drones, or smartphones—where re encoding would be time consuming and degrade fidelity.
