About Zerowidth Cleaner

Zerowidth Cleaner is an independent project built to make small text-cleaning tasks straightforward and private.

The tool removes a limited set of invisible Unicode formatting characters from text. It does not rewrite visible wording, identify authorship, or detect statistical text watermarks.

For a focused check that lists each finding by position before removal, use the zero width space checker.

For the text-only meaning of an AI watermark remover, use the AI watermark remover text checker.

Text cleaning happens in your browser. You can paste text or open a plain text, Markdown, or CSV file on your device.
