LosslessCut is a small video and audio tool for Mac users who need to cut large recordings fast without waiting for a long export. Instead of encoding the whole file again, it copies the data stream as it is, so trimming a long screen recording, a camera clip or a podcast file takes seconds and the picture and sound stay exactly as they were. It suits creators and anyone who pulls short parts out of long files.

Key Features

  • Cut and trim video and audio in seconds with no loss of quality
  • Merge cut segments or whole files that share the same codecs
  • Add, remove, replace or extract audio and subtitle tracks
  • Change the container format, for example from MKV to MP4, without encoding again
  • Find scenes, black frames and silence, and split a file at those points

FAQs

Does LosslessCut lower the quality of my video?

No. It copies the original data stream instead of encoding the file again, so the quality of the parts you keep stays the same as the source.

Is LosslessCut free to use?

Yes. The direct download from the project site and GitHub is free, and paid store builds exist for people who want store updates and wish to support the work.

Why does my cut start a little earlier than I marked?

Lossless cuts can only begin at a keyframe, so the app starts at the keyframe just before your chosen point.
