Text copied from a PDF, a formatted Word document, or a webpage often brings invisible passengers along with it, a double space left over from an old typing convention, a tab character used for alignment that means nothing once pasted somewhere else, three or four blank lines sitting where only one was ever intended, whitespace that's invisible until it starts causing visibly uneven spacing. This tool collapses multiple spaces, tabs, and stray line breaks down to a single space or line break, a narrow, mechanical whitespace cleanup rather than a broader text reformatting pass. Useful for cleaning up text copied from a PDF that brought along inconsistent spacing, collapsing several blank lines left behind after pasting from a formatted document, or normalizing tab characters that only made sense in their original layout.
