Zero-Width Space Remover
Instantly detect and strip hidden zero-width spaces (U+200B), non-breaking spaces, and invisible unicode control marks from text.
Private. 100% Browser-based processing. Zero server storage.
What is a Zero-Width Space & How to Remove It?
A zero-width space (ZWSP, Unicode U+200B) is an invisible character that occupies no visual space on screen. AI tools like ChatGPT and rich text editors frequently introduce ZWSPs, causing code crashes, broken searches, and formatting glitches. Our tool strips them instantly in your browser.
See the Difference Before & After Cleaning
Hidden artifacts and zero-width characters cause unexpected layout shifts, regex crashes, and AI detector flags. Here is how clean text compares.

Unicode Characters Removed & Filtered
Our browser engine detects and strips invisible formatting controls and non-printable unicode points automatically.
| Character Name | Unicode Hex | Impact & Behavior |
|---|---|---|
| Zero-Width Space (ZWSP) | U+200B | Invisible space added by AI models and rich text editors that causes regex crashes and code errors. |
| Zero-Width Non-Joiner (ZWNJ) | U+200C | Used in script typesetting, often accidentally pasted into plain text input fields. |
| Zero-Width Joiner (ZWJ) | U+200D | Used for combining emojis or characters, breaks character counts and string operations. |
| Byte Order Mark (BOM) | U+FEFF | Unicode character inserted at the start of text streams that breaks web compilers and JSON parsers. |

Frequently Asked Questions
Got questions about zero-width characters, AI formatting, or privacy? We have answers.
What is a Zero-Width Space (U+200B)?
A zero-width space is an invisible character used in digital typesetting to indicate word boundaries without introducing a visible gap. Large Language Models like ChatGPT frequently include them in output text.
Why do zero-width spaces break code and databases?
Because zero-width spaces are non-printable, developers cannot see them. However, compilers, database queries, and regex engine treat them as actual characters, causing syntax errors or string mismatch bugs.
Is my text uploaded to a server when cleaning?
No. AI Text Cleaner processes all text entirely within your local browser JavaScript engine. No data is transmitted to external servers.
How can I detect if text contains U+200B zero-width spaces?
Paste your text into the editor above and click 'Clean Text'. Our character inspector automatically highlights U+200B occurrences and displays exact counts.
Does this tool also strip Byte Order Marks (U+FEFF)?
Yes! It strips Byte Order Marks (BOM), soft hyphens (U+00AD), and all C0/C1 invisible control codes.
