Remove duplicate spaces, leading/trailing whitespace and blank lines
This tool cleans up messy whitespace in text: it collapses runs of repeated spaces into one, trims the spaces at the start and end of lines, and removes empty blank lines. Whitespace is invisible, so these problems hide in plain sight — text pasted from a PDF, a website or a spreadsheet often arrives padded with double spaces, stray tabs and trailing spaces you cannot see but that break alignment, inflate word counts and cause mismatches when the text is compared or searched.
Tidying it by hand is tedious and error-prone because you are fixing characters you cannot see. This tool does it in one pass, giving you clean, normalised text where one space separates words, lines have no leading or trailing padding, and blank gaps are closed. It is the quiet step that makes copied content behave: consistent spacing matters for code, data imports, search keys and anywhere two strings need to match exactly. Everything runs in your browser, so your text stays private.
Almost always because of invisible whitespace: a trailing space, a double space, or a tab instead of a space. Since these characters are not visible, the strings look the same but differ byte-for-byte. Normalising the spacing makes them match.
No. It keeps a single space between words and only removes the extras — duplicate spaces, leading and trailing padding, and empty lines. The text stays readable; it just loses the invisible clutter.
They are different characters that often look identical on screen. Mixed tabs and spaces are a common source of misalignment and failed comparisons, so normalising whitespace removes that ambiguity by producing consistent spacing.
No. The cleanup runs entirely in your browser, so nothing you paste is uploaded. You can safely tidy private documents, code or data.
