How Empty Line Removal Works
The tool splits text into individual lines and checks each for emptiness or whitespace-only content.
If trimming is enabled, leading and trailing whitespace are removed before filtering.
Processing time is linear (O(n)) and maintains the original line order.
All operations run in-browser for speed and complete data privacy.
