LosslessCut
Cross-platform FFmpeg GUI for lossless video and audio cutting, merging and remuxing — no re-encoding, no quality loss.
LosslessCut is a cross-platform desktop app built on FFmpeg for extremely fast, lossless operations on video, audio and subtitle files. Instead of re-encoding your footage, it copies the original data stream, which makes cutting nearly instant and keeps quality identical to the source. The main use case is rough-cutting large files from video cameras, GoPros and drones — extracting the good parts and discarding gigabytes without a slow export.
Beyond trimming, LosslessCut can merge files with matching codecs, add, remove or replace individual audio and subtitle tracks, remux between containers, take full-resolution snapshots, edit metadata and embedded chapter marks, and detect scenes or silence. Segments can be labelled and tagged, and cut lists can be imported and exported as MP4/MKV chapters, CSV, CUE, YouTube times or DaVinci Resolve and Final Cut Pro XML.
Compared with commercial editors like Adobe Premiere Pro or Final Cut Pro, LosslessCut is not a timeline editor — there are no transitions, effects or a rendering pipeline. It is built for one job: cutting and rearranging media without losing quality or time. It is free and open source under GPL-2.0; the developer offers paid App Store installs for convenience, but GitHub downloads are always free.
