Depending on your chosen mode, it strips lines with zero length, lines containing only whitespace (spaces or tabs), collapses consecutive empty lines into a single line break, trims leading/trailing blank rows, filters rows by custom RegEx patterns, or deduplicates repetitive entries.

Remove All mode completely eliminates every empty line from your text, resulting in no blank lines at all. Collapse Duplicates mode preserves single line breaks for paragraph separation but reduces multiple consecutive empty lines down to just one, which is ideal for formatting source code and Markdown documents while maintaining readability.
