About the Whitespace Cleaner
The Whitespace Cleaner removes extra spaces, tabs, and blank lines from text so it is consistent and ready to paste into code, content, or data. It helps developers, writers, and WordPress users tidy text copied from PDFs, emails, spreadsheets, or chat. Everything runs in your browser with plain JavaScript, so your text stays private and is never uploaded.

Frequently asked questions
Is my text uploaded anywhere?
No. All cleaning happens in your browser with plain JavaScript. Nothing is sent to a server or logged.
What does 'collapse multiple spaces into one' do?
It replaces any run of two or more spaces inside a line with a single space. Tabs are handled separately by the 'Convert tabs to spaces' option.
What is the difference between 'remove blank lines' and 'remove all line breaks'?
Remove blank lines deletes empty lines but keeps the line structure of the rest. Remove all line breaks joins every line into one continuous line separated by single spaces.
Why does the character count sometimes show characters added?
Converting tabs to spaces can increase the length, because one tab is replaced with four spaces. If that adds more than other options remove, the total goes up.
Does it work offline?
Yes. Once the page has loaded, cleaning runs locally in your browser, so the tool keeps working without an active connection.
