What to expect
How it works
Windows and classic Mac line endings are normalized to line feeds. The enabled transformations then run in order: tabs, per-line space collapsing and trimming, blank-line collapsing, and whole-document trimming. The result and removed-character count update immediately.
Know before using
Limits and edge cases
- Whitespace can be meaningful in source code, Markdown tables, poetry, and preformatted data; the default settings can change those formats.
- “Collapse repeated spaces” targets ordinary spaces, form feeds, and vertical tabs. A tab is changed only when tab conversion is enabled, and each tab always becomes exactly two spaces.
Common questions
Whitespace cleaner FAQ
Is whitespace cleaner free to use?
Yes. Whitespace cleaner is free to use.
Does whitespace cleaner keep my work private?
Yes. Your work stays private while you use the tool — nothing you enter is uploaded.
Can I trim line endings without collapsing spaces inside a sentence?
Yes. Keep “Trim line edges” on and switch “Collapse repeated spaces” off; the controls operate independently.
How many blank lines remain after collapsing?
A run of multiple empty separator lines becomes one empty line between the surrounding text blocks.
