LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files.
The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc. It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. There are also many more use cases. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work.

If you want to support my continued work on LosslessCut, and you want the advantage of a secure and simple installation process with automatic, stable updates, consider getting it from your favorite store:

 

For Linux I publish to the Snap Store:



If you prefer to download the executables manually, this will of course always be free (see also supported operating systems):

- macOS: Intel / Apple Silicon DMG (note that PKG does not work)
- Windows: 7zip (Windows 7, 8 and 8.1 is no longer supported after v3.50.0)
- Linux: x64 tar.bz2 / x64 AppImage / arm64 tar.bz2
- More releases - Note that APPX (Windows) and PKG (macOS) do not work
- Latest nightly builds 🧪

Note that the above are the only official downloads. There are also unofficial releases like Flathub (not maintained by me). Difference between App Stores and GitHub download? Please see FAQ.



LosslessCut is maintained by me alone and will always remain free and open source. If it's useful to you, consider supporting my work. Alternatively donate to the FFmpeg team because they are doing the world a huge favor.
