Shave gigabytes off video and audio files in seconds without loss of quality
Thousands of happy users
I've been looking a long time for a program like LosslessCut
You just saved my butt and kept me from missing a pretty important deadline over a stupid mistake. THANK YOU.
Before using this I had just spent 45 minutes exporting 1.5 seconds of video using my usual video editor, this did the whole thing in less than a second.
I use your program LosslessCut frequently and am amazed by how fast and simple it works, especially that everything really works without loss.
Thanks for your work on LosslessCut. I have years of personal video to cut through, and this is going to be a huge timesaver.
Great work! LosslessCut saves me a lot of time due to usability and good performance.
LosslessCut saved my day from endless FFmpeg trim commands, thank you and keep up the good work!
Traditional video editors

Any operation in a normal video editor
requires you to re-encode the whole file
which can take hours and you will
gradually lose quality every time you cut.


LosslessCut will do the same in seconds without losing quality

LosslessCut simply cuts the data stream and directly copies it over.

Other usage scenarios
  • Cut out commercials from a recorded TV show
  • Remove audio or video track from a file
  • Add music to a video (or replace existing audio track)
  • Include a subtitle into a video
  • Extract music, video or subtitle track from a video and cut it to your needs
  • Change format of a H264 TV recording from TS to MP4
  • Fix rotation of a video that has the wrong orientation flag set, e.g. phone recording
  • Quickly change a H264 MKV video to MOV or MP4 for playback on iPhone
  • Import a list of cut times from other tool as a EDL (edit decision list, CSV) and run these cuts with LosslessCut
  • Export a list of cut times as a CSV EDL and run these in another tool
  • Loop a video / audio clip X times quickly without re-encoding
* Which function is available depends on the file in question and which format/codec this file has
* This app is not for exact cutting. Start cut time will be "rounded" to the nearest previous keyframe, which may be a fraction of a second before your desired cut point, or up to several seconds, depending on the encoding.
Lightning Fast! It's like Magic

I believe software should be available to everyone, and LosslessCut will always be free for anyone to use.
