The safest and most common way to get the software is through the official LosslessCut GitHub repository . Because it is a portable application, it can be run directly from an external drive without installation.
LosslessCut is a powerful, open-source tool designed for extremely fast, lossless trimming and cutting of video and audio files. Unlike traditional video editors that re-encode files—a process that is time-consuming and reduces quality—LosslessCut performs a direct data copy. This allows users to extract specific segments from massive files, such as 4K drone footage or 12-hour recordings, in just seconds while maintaining the original quality. losslesscut download
