About this tool
Each option applies independently, so you can mix and match: collapsing repeated spaces turns a b into a b without touching line breaks, while collapsing blank lines turns three empty lines in a row into one, preserving intentional paragraph breaks rather than removing them entirely. "Remove all blank lines" is the more aggressive option — it drops every empty line, useful for cleaning up copy-pasted code or lists.
