LosslessCut

The Swiss Army Knife of Lossless Video/Audio Editing

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 a file is processed.

LosslessCut

LosslessCut will do the same in seconds without losing quality

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

• 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 and look at the code.

If LosslessCut brings you value, please consider supporting my continued work by purchasing it from your favorite store, or support me by donating.

FAQ

Why is it not free on the App Stores but free on GitHub?

I initially only released LosslessCut as a direct download from GitHub, as an unsigned/untrusted exe/binary file download. People were complaining that it’s hard to download/install the unsigned exe file, as they need to go through these dialogs saying that this file is a threat to your computer, and anti-virus complaining about executables downloaded from the internet. Some wanted a way to automatically update the app when new versions are out. This can both be achieved by downloading through the MS and Apple App Store. Microsoft charges money for signing binaries and a yearly fee for publishing to the Microsoft Store. Therefore I decided I can sell it in the MS Store for those who want to support my continued work and want to have the benefits it gives, while at the same time providing more experimental unsigned downloads as usual. Of course anyone is also free to build LosslessCut from source code.
