What does 'preserve paragraph breaks' do?

When enabled, blank lines (double line breaks) are kept as paragraph separators, but single line breaks within a paragraph are removed.

Can I replace line breaks with a custom character?

Yes. Choose 'Custom' from the Replace With dropdown and enter any character or string.

Is my text sent to a server?

No. Everything runs in your browser. Your text never leaves your device.

When would I use this tool?

Common uses: cleaning up copy-pasted PDF text, joining word-wrapped lines from emails, preparing text for a single-line API input.
