Frequently Asked Questions
What kinds of whitespace does this tool remove?
Depending on mode: leading whitespace (spaces/tabs at line start), trailing whitespace (at line end), multiple consecutive spaces condensed to one, or all whitespace including spaces within words. Tab characters can also be converted to spaces.
Why is removing trailing whitespace important?
Trailing whitespace is invisible but causes problems: Git diffs highlight it, some code reviewers reject it, and certain programming languages (Python strings, Markdown) treat trailing spaces as significant. Clean text without trailing spaces is a standard coding hygiene practice.
Will removing whitespace break Markdown formatting?
Possibly. Markdown uses two trailing spaces for a line break (<br>). Removing all trailing whitespace will convert these intentional breaks into paragraph merges. Be selective about whitespace removal when working with Markdown source.
