Text copied from the wild is full of invisible mess
Copy a paragraph out of a PDF, a spreadsheet cell or a web page and it arrives padded with double spaces, tabs, trailing spaces at the ends of lines and blank lines between paragraphs. None of it is visible until it breaks alignment somewhere else. This tool collapses runs of whitespace down to single spaces, strips the leading and trailing space from each line, and cleans up the gaps, so what you paste onward is uniform.
Each kind of whitespace is a separate decision
Collapsing internal runs of spaces is different from trimming the ends of lines, which is different again from removing blank lines entirely, and you rarely want all three every time. Treating them as separate options means you can normalise the spacing inside a paragraph while keeping the paragraph breaks, or flatten everything to a single clean block, depending on where the text is going next.
Why it matters beyond tidiness
Stray whitespace is not just ugly; it changes behaviour. A trailing space breaks an exact-match lookup, a double space throws off a diff, and inconsistent indentation confuses anything that parses by column. Normalising whitespace before you paste text into a form, a config file or a search box removes a whole category of "why does this not match" problems. The cleanup runs entirely in your browser.

Frequently Asked Questions
What counts as whitespace here?
Ordinary spaces, tabs, and the runs of them that build up between words and at the ends of lines, plus blank lines when you choose to remove them.
Will it join all my text into one line?
Only if you ask it to. Collapsing internal spaces and trimming line ends keeps your line breaks; there is a separate option for flattening everything into a single continuous block.
Why does trailing whitespace matter?
Because it is invisible but significant: it breaks exact-match comparisons, search lookups and diffs. Trimming it removes a common source of mismatches that are hard to spot by eye.
Does it remove blank lines between paragraphs?
Only when you enable that option. By default paragraph breaks are preserved so the structure of the text survives.
Is my text uploaded?
No. All the cleaning happens in your browser with JavaScript, so even sensitive text stays on your machine.
Privacy & Security
All processing happens locally in your browser — your text is never uploaded.
