LosslessCut trims, cuts and joins video in seconds, without re-encoding and without losing any quality.

Instead of rebuilding the whole video like a normal editor, it copies the parts you keep straight into a new file.

Version 3.70.2 arrived on 28 October 2026, and LosslessCut is free and open source for Windows, macOS and Linux.

What LosslessCut Actually Does

Drag in a video, mark the parts you want to keep, and export. A two-hour recording becomes a five-minute clip in the time it takes to copy the file, and the result looks exactly like the original.

  • Cut and trim phone, GoPro, drone or TV recordings, keeping several segments at once.
  • Join clips from the same camera into one file.
  • Manage tracks - remove an audio language, add a soundtrack, or pull out subtitles.
  • Change containers, such as MKV to MP4, without touching the video inside.
  • Save stills at full resolution from any frame.

The One Catch: Keyframes

Because nothing is re-encoded, cuts land on keyframes, the full pictures a video stores every second or so. Your start point can shift a little, and LosslessCut now warns you when there are too few keyframes near a cut.

If you need a cut on an exact frame, a re-encoding editor such as Avidemux or Shotcut is the better tool.

What Is New in 3.70

The 3.70 series updates the built-in FFmpeg to 8.1 with a security fix and adds a light and dark theme that can follow Windows.

The metadata editor got a big upgrade: copy tags from another file, set a language on every track at once, and get a warning when an HEVC file lacks the tag Apple devices need. Version 3.70.2 fixes black and silent scene detection on Windows.

Which Download to Pick

The download page has the current Windows x64, macOS and Linux builds. LosslessCut is portable on Windows: extract the 7z archive and run it.

Current versions need 64-bit Windows 10 or 11. For Windows 7, 8 or 8.1, the download page keeps version 3.50, the last one that runs there.

Who Should Look Elsewhere

If you want titles, transitions or effects, you need a full editor: Shotcut is free and simple, and DaVinci Resolve handles serious projects.

To just watch the finished clips, VLC Media Player plays everything LosslessCut saves.

To shrink a file or change its codec, HandBrake re-encodes it. For batch work on MKV tracks, MKVToolNix goes further.

Quick questions

Is LosslessCut free?

Yes. It is free and open source on GitHub, and that is the version offered here. Paid copies in the Microsoft Store and Mac App Store simply support the developer.

Does LosslessCut reduce video quality?

No. It copies the original video data without re-encoding, so the quality is identical to the source.

Why did my cut start a little early or late?

Cuts snap to the nearest keyframe. Move your cut point slightly, or try the experimental smart cut option, which re-encodes only the frames around the cut.

Which formats does it open?

Most common ones, including MP4, MOV, MKV, WebM, AVI and MPEG-TS, with H.264, HEVC, VP9 and AV1 video, because it runs on FFmpeg.
