Invisible Character Remover

Paste any text below and remove selected invisible, zero-width, spacing, and bidirectional formatting characters in one click — all processed locally in your browser. This targets a curated set of characters, not every possible invisible or formatting character in Unicode.

This tool’s cleaning code runs locally in your browser and does not upload or store the text you paste.

Choose what to remove

Removal categories Zero-width charactersZero Width Space, Zero Width Joiner/Non-Joiner, Word Joiner, ZWNBSP — removing ZWJ can change how some emoji sequences combine or display Format and invisible charactersSoft Hyphen, Mongolian Vowel Separator, invisible math operators — soft hyphen can carry intentional hyphenation information Unicode space charactersNon-breaking, typographic, and ideographic spaces — some of these (like non-breaking space) are often used intentionally for spacing or line-break control Bidirectional control charactersDirectional marks (LRM/RLM), embedding, override, and isolate controls — can be intentional in multilingual text

All four categories are selected by default, but several of these characters can be used intentionally (non-breaking spaces, soft hyphens, bidi marks, joiners in emoji or scripts). Review the Before/After result below before relying on the cleaned text.

Common Reasons to Remove Invisible Characters

Duplicate-looking usernames, filenames, or slugs that may fail comparison checks because of hidden characters — though normalization, confusable characters, and platform-specific rules can cause similar issues too.
Copy-pasted content that carries unwanted invisible or formatting characters, for example from PDFs, Word documents, or web pages.
Form fields, spreadsheets, or database values that silently break validation or sorting.
Text that looks blank but won’t submit because it isn’t actually empty.
Cleaning up before publishing, importing data, or sharing text across platforms.

Frequently Asked Questions

Is cleaning reversible?

Cleaning only changes the copy you take out of this tool. Your original pasted text isn’t altered anywhere else, so keep a backup of the original if you might need those characters again.

Will this affect normal spaces or line breaks?

Regular space-bar spaces, tabs, and line breaks are left alone. Only the specific invisible and formatting characters in the checked categories above are removed — other unusual Unicode characters outside this tool’s lists are left untouched too.

Is it safe to use on text with emoji?

The tool doesn’t target emoji code points directly, so a standalone emoji passes through untouched. However, some emoji are built from multiple code points joined with Zero Width Joiner (U+200D) — if you have that category checked, removing the ZWJ can change how a combined emoji sequence displays. Uncheck “Zero-width characters” if you need to preserve multi-part emoji exactly as pasted.

Does this help with file names?

It can help. Filenames or identifiers that look identical but behave differently sometimes contain one of the hidden characters this tool targets, and cleaning them can reduce that risk. It won’t address every possible mismatch source, though — Unicode normalization, confusable characters, and filesystem-specific rules can also cause filenames to behave unexpectedly.

Is my text sent to a server?

This tool’s cleaning code runs locally in your browser using JavaScript and does not upload or store the text you paste. We can’t speak for other scripts that might run elsewhere on a page (analytics, browser extensions, etc.), but the remover itself sends nothing to a server.

How is this different from the Detector tool?

The Detector identifies supported hidden characters from its own list and reports where they occur, without changing your text. This Remover tool actually deletes the characters in the categories you select. Both tools work from a curated list of characters rather than scanning for every possible invisible Unicode character.

Can I clean more than one piece of text at a time?

Yes, use Batch Mode above. Paste multiple lines, clean them all together, and download the result as a .txt file.
