LosslessCut

LosslessCut is a free, open-source video cutter made by developer mifi. It trims and joins videos without re-encoding, so cuts take seconds and quality stays perfect. It is built on FFmpeg and works as a simple visual app. You can also merge files, pull out audio, take full-resolution snapshots, and change containers. It runs on Windows, Mac, and Linux. A keyboard-driven workflow makes repeat cuts very fast. Get it from the official GitHub releases page. LosslessCut is trusted by creators worldwide for fast, exact cuts.

Key Features

1. Lossless Cutting

Cuts copy the data stream instead of re-encoding. Trimming takes seconds and the picture stays exactly the same.

2. Merge and Rearrange

Join clips from the same camera without re-encoding. You can also reorder segments before exporting.

3. Smart Cut

An experimental mode re-encodes only the few frames at cut edges. This gets near frame-accurate cuts with tiny quality cost.

4. Format Remuxing

Change the container, like MKV to MP4, without touching the video. This makes files play on more devices fast.

5. Track Editing

Add, remove, or replace audio, subtitle, and attachment tracks. Extract audio tracks into separate files easily.

6. Snapshots and Frame Export

Save any frame as a full-resolution JPEG or PNG. Export frames by scene change for quick thumbnail sets.

7. Detection Helpers

Find black scenes, silent parts, and scene changes automatically. It can even map the GPS track in DJI drone footage.

8. CLI and Automation

A basic command line and HTTP API support batch jobs. Import and export cut lists as CSV or edit decision lists.

Frequently Asked Questions (FAQ)

What is LosslessCut used for?

Quick trims, cutting commercials from recordings, merging clips, and pulling audio from video. It is for fast jobs, not full editing.

Is LosslessCut really free?

Yes. It is open source under the GPL-2.0 license and free on GitHub. There are no paid features or limits.

Why is LosslessCut faster than normal editors?

Normal editors re-render every cut, which takes time and loses quality. LosslessCut copies the streams directly, so it finishes in seconds.

Are LosslessCut cuts frame-accurate?

Cuts snap to keyframes, so they may shift slightly. The experimental Smart Cut mode re-encodes edge frames for better accuracy.

What is the difference between LosslessCut and HandBrake?

LosslessCut cuts without re-encoding for zero quality loss. HandBrake re-encodes to convert formats and shrink files.

Conclusion

LosslessCut is the fastest way to trim video without quality loss. It cuts, merges, remuxes, and extracts in seconds. The interface is simple and keyboard-driven. It suits anyone who needs quick, exact cuts — from drone pilots to lecture recorders — at zero cost. It is a must-have companion tool for every video editor. Grab it from GitHub.
