Zero width spaces

Paste text to find U+200B zero width spaces. Each one appears as a labelled token you can select.
What is a zero width space?
A zero width space is the Unicode character U+200B. It takes up no space on screen and only tells software where a line may wrap. When text is copied, it often comes along unseen, sitting in the middle of a word or number.

Why zero width spaces appear in copied text
Copied web pages
Sites and CMS editors insert U+200B to allow line breaks in long words, URLs and code samples.
PDFs and documents
Text extracted from PDFs or word processors can carry break hints that become hidden characters.
Chat and social apps
Messages are sometimes padded with zero width spaces, which then travel along when copied.
Deliberate hiding
Zero width spaces are inserted inside words to break keyword filters or fingerprint copied text.
What zero width spaces can break
Code and identifiers
A variable or JSON key with U+200B inside is a different name, so code fails in confusing ways.
URLs and links
A link can look right but point nowhere, or a pasted domain can fail to resolve.
Search and matching
Spreadsheet lookups, database queries and find-in-page miss text that looks identical.
Form validation
Emails, usernames and IDs pasted with a hidden character fail checks for no visible reason.
Characters this tool does not remove

Frequently asked questions
What is a zero width space?
A zero width space is the Unicode character U+200B. It has no visible width and tells software where a line is allowed to break. In copied text it usually appears by accident, hidden inside words, numbers, IDs or URLs.
How do I remove a zero width space?
Paste your text into the Zero Width Space Remover, check the highlighted ZWSP tokens, then select Remove zero width spaces. Copy the cleaned result. Only U+200B is removed; all other characters stay the same.
Why are zero width spaces in my text?
They are often added by websites, PDFs, chat apps, content management systems and word processors to control line breaking, and they survive copy and paste. Some are also inserted on purpose to hide text or break keyword matching.
Can zero width spaces break code or URLs?
Yes. A zero width space inside a variable name, JSON key, command or URL makes it a different string. Code may fail to compile, commands may not run, and links may point to the wrong address while looking correct.
Does this tool remove zero width joiners?
No. Zero width joiners (U+200D) and zero width non-joiners (U+200C) are kept because they are needed for emoji sequences and for correct shaping in scripts such as Persian, Arabic and Hindi. Use the Invisible Character Detector if you want to review them.
