What Are Invisible Characters?
Invisible characters are Unicode code points that render as nothing on screen but occupy space in your text data. Common culprits include the zero-width space (U+200B), byte order mark (U+FEFF), soft hyphen (U+00AD), and various bidirectional control characters. They typically enter your text when copying from websites, PDFs, or rich-text editors.
These characters cause real problems: string comparisons fail unexpectedly, database searches return no results, API calls produce errors, and users report "weird spaces" that cannot be deleted normally. Developers, content writers, and data analysts encounter this issue regularly when working with copy-pasted content.
This tool scans your pasted text for all known invisible characters, reports each type and its count, then provides a fully cleaned version ready to copy. Normal spaces, tabs, and line breaks are always left untouched.
FAQ
Some websites insert zero-width spaces for word-breaking or anti-scraping purposes, and bidirectional control characters for right-to-left text layout. Copy-pasting brings them along silently.
No. Only known invisible Unicode characters are removed. Regular spaces (U+0020), tabs (U+0009), and newlines (U+000A) are preserved exactly as-is.
