Remove Line Breaks & Fix Broken Text
Remove unwanted line breaks and reflow paragraphs from pasted text. Also strips zero-width characters, BOM, and invisible Unicode garbage. Free, in-browser.
Copy text out of a PDF and every line ends with its own hard break; paste it into an email or CMS and you get a staircase of short lines. This tool removes the breaks and reflows paragraphs — keeping the breaks you want (between paragraphs) and dropping the ones inside sentences.
It also cleans what you cannot see: zero-width spaces, soft hyphens, byte-order marks, and other invisible Unicode that PDF copy-paste leaves behind and that breaks search, spreadsheets, and code.

How the deep cleaner finds invisible characters — illustrated
Invisible characters are real Unicode code points that render with zero width — they occupy a position in the string but show no glyph. PDF copy-paste, web scraping, and AI output routinely smuggle in zero-width spaces (U+200B), byte order marks (U+FEFF), soft hyphens (U+00AD), control characters (U+0000–U+001F), and bidi overrides (U+202E). The cleaner scans every code point against a table of known ranges and strips each match in a single left-to-right pass.
Each highlighted diamond is a hidden code point the scanner matches and removes — the visible letters never change.
Priya is a QA engineer who just pulled a 2,400-character test case out of a PDF spec. The formatter silently rejects it, so she runs it through this cleaner to find out why.
- Scan:The tool reports 14 invisible characters in the 2,400-character string — 3 zero-width spaces (U+200B), 1 byte order mark (U+FEFF), 2 soft hyphens (U+00AD), 6 control characters, and 2 bidi overrides (U+202E).
- Clean:She keeps all 11 options enabled and runs the cleaner; the 14 hidden code points are removed in one pass, leaving 2,386 visible characters.
- Inspect:The Removal Details panel breaks the count down per category, so she can tell which source introduced each character.
- Verify:She re-pastes the cleaned output — the formatter accepts it, and a diff-checker confirms that only invisible characters changed.

Frequently asked questions
How do I remove line breaks but keep paragraphs?
Paste the text and use the reflow option: single line breaks inside paragraphs are removed, while double breaks (blank lines) are preserved as paragraph separators. The result is clean flowing text with the original paragraph structure intact.
Why does my pasted text contain invisible characters?
PDF generators and some websites insert zero-width spaces, soft hyphens, and byte-order marks that are invisible on screen but real to software — they break exact-match search, spreadsheet lookups, and code compilation. The deep-clean mode strips them all while leaving visible text untouched.
