This is a whitespace cleaner for text that arrived messy, the kind you get when copying from a PDF, an email or a document, where stray line breaks, double spaces and blank lines are common.

It gives you a set of options you can combine: trim spaces from the ends of lines, collapse runs of spaces into one, remove blank lines, join everything onto a single line, or strip all whitespace entirely.

Everything runs in your browser, so your text never leaves your device.

The problem it solves most often is pasting from a PDF, which stores text with fixed line breaks and padding for layout. The result usually has line breaks in the middle of sentences and doubled spaces, which this tidies up.

Collapsing spaces replaces multiple spaces or tabs with a single space without touching line breaks, while removing blank lines drops the empty rows that pile up between paragraphs.

To turn broken lines back into flowing paragraphs, join them onto one line. To get a single continuous string with no spacing at all, remove all whitespace, which overrides the other options.
