Tips

• Collapse multiple consecutive spaces into a single space instantly
• Trim trailing whitespace from every line to clean up pasted code
• Remove consecutive blank lines to tighten up copied text or logs

Fun Facts

• There are 25 different whitespace characters in Unicode, including the zero-width space (U+200B) which is invisible but still counts as a character.
• The programming language Whitespace, created in 2003 by Edwin Brady and Chris Morris, uses only spaces, tabs, and line feeds as its entire instruction set.
• Git's 'git diff --check' specifically warns about trailing whitespace because it causes unnecessary merge conflicts and clutters version history.

FAQ

What counts as whitespace?

ASCII space, tab, newline, carriage return, form feed, vertical tab, and zero-width / non-breaking space. The normalizer can collapse, trim, or convert any of these.

Default settings do what?

Collapse consecutive spaces/tabs to a single space, trim trailing whitespace from each line, drop runs of blank lines to a single blank line. Most common 'clean up pasted text' rules.

Does it touch indentation?

Optional — toggle 'preserve indentation' to keep leading whitespace untouched (for code). Default mode collapses every sequence, which breaks indentation.

What about Unicode spaces?

The tool detects non-breaking space (U+00A0), narrow no-break space (U+202F), and zero-width space (U+200B) and normalizes or removes them per your settings.
