Why Lossless Trimming?

This tool uses "stream copy" mode - it extracts the portion you want without re-encoding the video. This means:

  • No quality loss: The output is identical quality to the input
  • Instant speed: No time-consuming re-encoding process
  • Smaller processing load: Works great even on older devices
