You come home with a card full of GoPro or drone clips, and only a few minutes of each are worth keeping. LosslessCut cuts those parts out without a slow re-encode, so the picture quality stays exactly as recorded. This page covers version 3.70.2 for Windows, which is free. The download link points to github.com, where the developer publishes the file.
A GUI for FFmpeg from Chris Huang
The developer is Chris Huang, and the project is hosted in a GitHub repository. The package ID is ch.LosslessCut, and the license is GPL-2.0-only.
The project describes its goal as becoming the ultimate cross platform FFmpeg GUI. FFmpeg does the heavy work underneath, and LosslessCut gives it a window for fast operations on video, audio, subtitle and related media files.
Trimming without re-encoding
The main job is lossless trimming and cutting of video and audio. It suits rough-cutting large files from a video camera, GoPro or drone, where you keep the good parts and drop many gigabytes of footage.
Because the program does an almost direct data copy, it skips the slow re-encode and avoids quality loss. You can also add a music track or a subtitle track to a video without encoding it.
Size, version and Windows details
The Windows build is version 3.70.2 and weighs 240.5 MB. Both its release date and its last update are October 28, 2026. The price is free.
Check the GitHub page for system requirements before installing.
LosslessCut pros and cons
Pros
- Free to use, with a GPL-2.0-only license
- Cuts video and audio without re-encoding, so quality is preserved
- Near direct data copy makes operations very fast
- Can add a music or subtitle track without encoding

Is LosslessCut safe?
LosslessCut is released under GPL-2.0-only, and the listing names Chris Huang as the developer. The linked github.com page is the official source for version 3.70.2, a 240.5 MB package, so take the file from that link and not from a re-upload. Since the app mostly copies data through FFmpeg instead of re-encoding, keep your original footage until you have checked the trimmed result.
