Zero Width Space Remover (U+200B)

What is a zero-width space (U+200B)?

A zero-width space is a Unicode character with no visible glyph. It occupies a position in the string — between words or inside tokens — without adding a printable space. AI chat exports, web copy, and PDF paste operations frequently introduce U+200B without the author noticing.

Because it is invisible, users discover zero-width spaces only when something breaks: a regex that should match does not, a find-and-replace misses a phrase, or Word shows inexplicable cursor jumps. A dedicated remover enumerates and deletes each instance.

Our tool removes U+200B along with related zero-width joiners and non-joiners often found in the same contaminated paste.

In Unicode terminology, U+200B belongs to the Cf (format) category — characters that control layout or line breaking without rendering a visible symbol. Unlike a regular space (U+0020), a zero-width space does not advance the cursor visually, yet it still counts as a character in string length, byte size, and database column limits. That mismatch between what you see and what the computer stores is the root of most U+200B headaches.

Some writing systems use zero-width spaces legitimately for script-specific typography, but English-language AI paste workflows almost never need them. When ChatGPT, Claude, or Gemini output lands in your editor, stray U+200B bytes are artifacts of the export pipeline — not intentional formatting you should preserve.

Common zero-width space symptoms

Double-click selection stops mid-word. URL or email validation fails despite looking correct. SQL or code strings fail equality checks. LMS word counts disagree with your editor. Each symptom can trace back to invisible bytes rather than user error.

Developers debugging APIs sometimes receive JSON with zero-width spaces inside keys — cleaning the payload before parsing saves hours. Writers merging AI paragraphs into a master doc should strip U+200B before applying styles.

Search engines and site-internal find tools index the raw string. If a product name or heading contains U+200B between syllables, queries that look identical to the human eye will not match. E-commerce teams copying supplier descriptions from web portals hit this constantly when bulk-importing SKU text.

Version control diffs can show a line as changed when the visible text is identical — only a hex view reveals the extra zero-width byte. Running removal before commit keeps blame logs honest and prevents spurious merge conflicts across branches that edited the same paragraph.

Accessibility tools that read text aloud may pause oddly at zero-width positions, producing a stutter effect in screen-reader output. Cleaning U+200B before publishing web content improves both machine readability and assistive-technology experience.

Remove vs. detect zero-width spaces

Use our zero-width space detector page if you want a report-first workflow; this remover page assumes you already know U+200B is the likely culprit. Both use the same scanning engine.

After removal, paste into your target environment and re-test the operation that failed. If problems persist, scan for soft hyphens or byte-order marks with our broader invisible-character tools.

For batch workflows, paste one section at a time rather than an entire manuscript. Large pastes can hit browser memory limits, and isolating the problematic paragraph speeds up diagnosis when only a single block misbehaves.

If you collaborate in Google Docs or Notion, clean text locally before sharing the final version. Real-time editors sometimes re-insert formatting characters when multiple users paste from different sources, so a last-pass U+200B strip before export is cheap insurance.

How do I type a zero-width space intentionally?

U+200B is usually inserted by software, not typed. AI exports and web paste are the common sources this remover targets.

Will removing U+200B collapse my words together?

No. Normal visible spaces remain. Only zero-width code points are deleted.

Does this fix broken regex matches?

Often yes, when U+200B sat inside the pattern or haystack. Clean the string, then rerun your regex.

Is U+200B an AI watermark?

It can be used as a covert channel marker in AI output. Whether intentional or accidental, removing it is safe for visible text.

Is this watermark checker free?

Yes. You can scan up to 500 words without an account. Sign in for longer documents, full cleaned text, and a character-level breakdown of every hidden marker removed.

Is my text stored when I use the checker?

We process your text only to return a detection report and cleaned output. We do not retain the content of your pasted text for any other purpose.
