How do I normalize whitespace?

Paste your text in the input panel and choose a mode: All (full cleanup), Trim Lines, Collapse Spaces, Single Space, or Remove Blank Lines. The output updates instantly.

What does the 'All' mode do?

'All' mode applies a full cleanup: trims leading and trailing whitespace from every line, collapses multiple consecutive blank lines to a single blank line, and strips leading/trailing whitespace from the entire text.

Is the whitespace normalizer free?

Yes, completely free. All operations run entirely in your browser — no data is sent to any server, and no signup is required.
