In CommonMark, two trailing spaces signify a hard line break (<br>). Accidental trailing whitespace creates unexpected line breaks and triggers annoying Git diff warnings.
Does this cleaner delete double-space line breaks?
Our smart algorithm detects intentional two-space line breaks and preserves them while stripping 3+ redundant spaces.
Can I use this before running a linter like markdownlint?
Yes! This tool automatically resolves common markdownlint rules such as MD009 (no trailing spaces) and MD012 (no multiple consecutive blank lines).
