Text Cleaner (Whitespace & Line Breaks)
Strip extra spaces, tabs, empty lines and stray line breaks from pasted text in one pass — with each cleanup step as an on/off toggle.

How It Works
Each cleanup rule targets a specific, well-defined problem, and you can toggle any of them independently: collapsing repeated spaces into a single space, trimming leading and trailing whitespace from every line, removing empty lines, converting tabs to spaces, joining wrapped lines back into full paragraphs, and stripping invisible characters such as the zero-width space (U+200B) — a character with no visible glyph that often rides along silently when text is copied from a web page or a chat app, and that can quietly break search, string comparison, or form validation without you ever seeing why.
Line-ending normalization solves a related but different problem: Windows writes a line break as two characters, carriage return plus line feed (\r\n), while Unix, Linux and modern macOS use a single line feed (\n). Mixing the two inside one document is invisible on screen but can cause visible glitches elsewhere — extra blank lines in one editor, a script that silently fails to split lines correctly, or a diff tool that flags every line as changed. Normalizing everything to one convention removes that inconsistency.
What to Know
- Every option is independent. You can, for example, remove only empty lines while leaving spacing and tabs untouched.
- Zero-width characters are genuinely invisible. You cannot spot them by looking at the text; they only show up as broken search results, mismatched string comparisons, or unexpected line wrapping.
- "Join wrapped lines" is pattern-based. It merges a line that doesn't end in sentence-ending punctuation with the next line, undoing the hard breaks that PDF-to-text copying often inserts mid-sentence, while leaving genuine paragraph breaks (blank lines) alone.
- Nothing leaves your browser. Cleaning happens locally as you type, with no text uploaded to a server.
- It covers the classic real-world cases. Text copied from a PDF that inserts a line break after every sentence, a spreadsheet export riddled with double spaces, or code with tabs and spaces mixed inconsistently are all handled by the same toggles.
Frequently Asked Questions
What exactly is a zero-width character, and why does it matter?
It's a character like the zero-width space (U+200B) that renders no visible glyph at all — it takes up no space on screen but still exists in the underlying text. It commonly gets copied along silently from web pages or chat apps, and can break exact-text search, string comparisons, and some form validations, all without any visible sign that something is wrong. Because it has no visual footprint, the only reliable way to remove it is to run a cleanup pass rather than to try to spot it manually.
Why do line endings even matter if the text looks the same?
Windows encodes a line break as two characters (carriage return + line feed, \r\n), while Unix, Linux and modern macOS use just one (line feed, \n). A document mixing both looks identical on screen but can behave differently across editors, scripts, and diff tools — normalizing to one convention prevents that inconsistency from causing problems later.
Can I run only one cleanup step and skip the rest?
Yes. Every option — collapsing spaces, trimming, removing empty lines, tab conversion, line-ending normalization, joining wrapped lines, stripping invisible characters — has its own independent toggle, so you fix only what's actually broken in your specific text.
How does "join wrapped lines" decide where paragraphs really end?
It treats a line that doesn't end in punctuation like a period, question mark or similar as a mid-sentence break and merges it with the next line — this specifically undoes the artificial line breaks that PDF-to-text extraction often inserts after every visual line, while leaving blank lines (genuine paragraph breaks) untouched.
Is any of my pasted text sent to a server?
No. All cleaning operations run in JavaScript directly in your browser as you type — nothing is uploaded, logged, or stored anywhere, which means it's safe to use even on sensitive or unpublished content.
