What Are Invisible Characters & How to Fix Them?
Invisible characters are hidden unicode control codes (such as U+200B, U+00AD, U+200E) that exist in text without displaying visually. They cause silent database errors, broken searches, and syntax bugs. Our tool sanitizes your text instantly in your browser.

Frequently Asked Questions
Got questions about zero-width characters, AI formatting, or privacy? We have answers.
How do invisible characters get into my text?
Invisible characters are created when copying text from PDFs, formatted websites, Microsoft Word, or LLM AI outputs (ChatGPT/Claude). They represent hidden layout instructions.
Will removing invisible characters alter my visible text?
No. Only non-printable control marks, zero-width spaces, and soft hyphens are removed. All visible letters, numbers, and punctuation remain untouched.
Why are soft hyphens (U+00AD) harmful in web content?
Soft hyphens are invisible layout codes that break search engines from matching keywords. Removing them restores clean keyword indexing.
How do directional formatting marks (U+200E, U+200F) affect text?
Directional marks force text alignment in bi-directional scripts (such as Arabic or Hebrew). In English text, they cause unexpected cursor jumping.
Can I inspect the visual diff of removed characters?
