How to trim videos instantly without losing quality

LosslessCut is the Swiss Army Knife of lossless video and audio editing. It solves the frustrating problem of waiting hours for a standard video editor to re-encode a massive file just to cut out a few seconds of footage. By copying the data stream directly, it shaves gigabytes off your files in seconds. Follow these steps to start trimming:

  1. Import Your Media File
    Open the LosslessCut application and drag and drop your heavy video or audio file (like an MP4, MKV, or MOV) directly into the main window to load it into the timeline.
  2. Set Your Start and End Points
    Use the playback controls or scrub through the timeline to find the part you want to keep. Click the < icon (or press 'I' on your keyboard) to set the start point of your cut, and the > icon (or press 'O') to set the end point. You can create multiple cut segments from a single file.
  3. Manage Tracks (Optional)
    If your video has multiple audio tracks or subtitles, click the Tracks button. You can easily uncheck an audio track to strip the sound, or extract a specific subtitle track seamlessly.
  4. Export in Seconds
    Click the Export button. Because LosslessCut doesn't re-encode the video, your new trimmed file will be saved to your hard drive almost instantaneously, maintaining 100% of the original quality.
Pro Tip: Need to combine several clips from a GoPro or smartphone? You can use the "Merge" feature to concatenate multiple videos of the exact same resolution and codec into one large file instantly!

Frequently Asked Questions

LosslessCut is incredibly fast because it does not re-encode the video. However, this means it is not meant for exact, frame-by-frame cutting. The software must round your cut time to the nearest previous "keyframe." Depending on how your video was originally encoded, this keyframe might be a fraction of a second or up to several seconds before your desired cut point.

The free version downloaded directly from GitHub is an unsigned executable file. Windows SmartScreen and some antivirus programs will flag it simply because it lacks an expensive digital certificate. It is perfectly safe. If you want to bypass these warnings and receive automatic updates, you can purchase the signed version from the Microsoft Store or Mac App Store to support the developer.

Yes! This is a process called "remuxing." LosslessCut allows you to quickly change container formats (like MKV, MOV, or TS) to an MP4 for easier playback on devices like iPhones or TVs, all without losing quality or waiting for a long rendering process.

No. LosslessCut reduces file size solely by cutting out the unwanted parts of the video stream. It does not use compression algorithms to shrink the visual quality of the remaining footage. If you need to shrink a whole video via compression, you will need to use a dedicated transcoder tool like HandBrake.
