What this tool does
Whitespace Cleaner tidies up the invisible mess that sneaks into text copied from PDFs, spreadsheets, emails, and code. Toggle exactly the fixes you want: trim leading and trailing spaces from every line, collapse runs of multiple spaces down to one, remove blank lines, convert tabs to a chosen number of spaces, or strip every whitespace character entirely. The result updates live as you type and can be copied with one click.
How the options combine
The operations run in a sensible fixed order so the toggles cooperate instead of fighting. Tabs are expanded to spaces first, then each line is trimmed, then multiple spaces are collapsed, then blank lines are removed. "Remove all whitespace" runs last and wins over everything, producing a single unbroken string with no spaces, tabs, or line breaks. Because each step is a pure text transformation, the same input with the same toggles always gives the same output.
Frequently asked questions
Is any of my text uploaded to a server?
No. All cleaning happens locally in your browser with JavaScript. Your text is never sent, stored, or uploaded anywhere, so it stays completely private.
What is the difference between 'collapse multiple spaces' and 'remove all whitespace'?
'Collapse multiple spaces' turns each run of two or more spaces into a single space while keeping words and line breaks intact. 'Remove all whitespace' deletes every space, tab, and newline, joining the text into one continuous string.
What is the difference between 'collapse multiple blank lines' and 'remove blank lines'?
'Collapse multiple blank lines to one' reduces a run of two or more blank lines down to a single blank line, so paragraph breaks are preserved — ideal for text pasted from PDFs or emails with big gaps. 'Remove blank lines' deletes every blank line entirely.
Does 'convert tabs to spaces' affect indentation?
Yes. Each tab character is replaced with the number of spaces you choose (4 by default). Set it to a smaller or larger value to match your preferred indentation width; setting it to 0 removes tabs entirely.
