Invisible Character Detector
Find and remove hidden or zero-width characters — like zero-width spaces and non-breaking spaces — that sneak into copied text and break things.
About the Invisible Character Detector
The Invisible Character Detector processes your input right in the browser and updates the output as you type. Nothing you paste is uploaded, logged, or stored, so it's safe for private text, tokens, or code you control. It's free with no sign-up, no rate limits, and no ads interrupting your workflow — copy the result and get on with your work.
Worth Knowing
Some of the most baffling text bugs come from characters you can't see. A zero-width space copied from a website can silently break a URL or a password; a non-breaking space pasted from a word processor can fail an exact-match search or a code comparison even though the text looks identical. This tool scans for the usual culprits — zero-width spaces and joiners, the byte-order mark, and non-breaking spaces — reports exactly what it found, and hands back a cleaned version with the invisibles removed or normalized to ordinary spaces.
