What the whitespace remover does

Text copied from PDFs, Word documents, websites, emails, and spreadsheets can contain hard wraps and invisible formatting. This tool normalizes Windows CRLF, old Mac CR, and Unix LF line endings before applying the options you select. Preserve paragraphs is useful for PDF prose: it joins visual line wraps inside each paragraph while keeping blank-line boundaries.

Whitespace in plain language

  • Line break: starts the next line. A single break is often an unwanted hard wrap in copied PDF text.
  • Paragraph break: a blank line separating two blocks of text.
  • Tab: an indentation character that can look like several spaces.
  • Non-breaking space: U+00A0 or narrow U+202F, often copied from Word or the web; it prevents wrapping but usually looks like a normal space.
  • Zero-width character: an invisible U+200B, U+200C, U+200D, or U+FEFF character that may appear in pasted web text.

Suggested workflow

  1. Paste, type, drop, or choose a local .txt file.
  2. Keep Preserve paragraphs for prose, or choose Join all lines for a list or form field.
  3. Select a space, comma, or custom separator and adjust More options if needed.
  4. Select Clean text, compare both fields and statistics, then copy or download the result.

Frequently asked questions

Is my text uploaded?

No. Text and local .txt files are processed only in your browser and are not sent to Starlight Tools. Clearing the tool or closing the page removes the working text.

How does Preserve paragraphs work?

It joins single line breaks inside each paragraph using your selected separator, while keeping blank-line paragraph boundaries. With Collapse multiple blank lines enabled, every paragraph boundary becomes one blank line.

How do I replace line breaks with commas or custom text?

Choose Comma or Custom separator under Replace joined breaks with. Enter any custom text you need, then select Clean text.

Why does copied PDF text have hard line breaks?

PDFs often store text by its visual lines rather than as flowing paragraphs. Copying can preserve those line endings, so sentences wrap in the wrong places.

What is the difference between removing spaces and removing all whitespace?

Collapsing spaces keeps one normal space between words. Remove all whitespace deletes spaces, tabs, and line breaks, so words run together.

Is there a text-size limit?

There is no fixed server limit because nothing is uploaded. The practical limit depends on your browser and device memory, and very large files may process more slowly.

Does it work on mobile?

Yes. The tool, local file picker, copy action, and download action work in modern mobile browsers, subject to browser permissions.

Can cleaning damage code or JSON?

Yes. Line breaks, spaces, and indentation can be meaningful in code, JSON strings, YAML, Markdown, poetry, addresses, and other structured text. Compare the result before using it.
