Losslesscut - Portable __hot__ Download
LosslessCut is available for Windows, macOS, and Linux. The "portable" aspect means there is no installation wizard or registry changes required.
The official DMG contains a .app bundle. While not "portable" in the purest sense, you can drag that .app to any folder (including an external drive) and run it without installation. No admin rights needed. losslesscut portable download
