LosslessCut · 3.70.1

Trim unwanted footage in a few steps

Mark a segment’s start and end, then export it in a desktop interface. Useful for preparing long recordings before editing, without re-encoding in the usual lossless workflow.

Where it helps

Prepare a long interview or tutorial recording by keeping the useful section before taking it into your editor. Start with one segment; no Claude, Codex or cloud upload is needed.

Start here: download the app for your computer

A computer: 64-bit Windows 10/11, macOS 12+, or Linux compatible with the x64 build. Windows needs a 7z extractor; on Mac choose Apple Silicon or Intel. Check the release requirements for your computer.

Official GitHub downloads are free under GPL-2.0. Trimming local files needs no subscription, AI account or API credits. Paid app-store editions are an optional way to support the project.

Original installation instructions ↗

From a long file to a clip you can review

  1. Choose your computer’s download. Windows: extract the 7z and run LosslessCut.exe from its folder; macOS: open the DMG and drag the app to Applications; Linux: allow the AppImage to run as a program in file properties, then open it; check your distribution’s requirements.
  2. Open the app and drag in a short video. Mark the start and end of the section to keep on the timeline; default shortcuts are I for start and O for end.
  3. Click Export, review the output folder and filename, then confirm export. Play the result and check the cut points and audio before using it.

By default, selected segments are kept. Check the export mode before confirming, and keep your original during the first trial.

Limits to understand

  • Lossless cuts may start near a keyframe rather than the exact requested moment. Review the output; Smart Cut is experimental.
  • This is not a full editor for effects, titles and transitions. Some media formats need different playback or export settings.
  • Upstream treats newer GitHub builds as public beta tests, so bugs are possible. We verified sources, links and this site; we did not install the app or benchmark cut quality.
