Finding a stray tab

Pasting "Password" copied from a web page with an invisible zero-width space inside shows a red [U+200B] marker between "Pass" and "word", and Hidden Unicode marks counts 1.

FAQ
Frequently asked questions
Quick answers to common questions about the Whitespace Visualizer.
What does the Whitespace Visualizer do?
It reveals whitespace and hidden characters in your text by marking spaces, tabs and line breaks with visible symbols, and flagging hidden Unicode characters in red.
Is the Whitespace Visualizer free to use?
Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.
Is my text safe when I use this tool?
Yes. Your text is processed entirely on your own device — nothing is sent to a server.
What do the symbols · , → and ↵ mean?
A · marks a space, a → marks a tab, and a ↵ marks a line break, so you can see exactly where each one occurs in your text.
What kinds of hidden characters does it flag in red?
It calls out characters that are normally completely invisible, such as zero-width characters and byte-order marks, which can otherwise cause confusing bugs.
Do I need to click a button to see the visualization?
No. It updates live as you type or paste text into the box.
Why would invisible characters end up in my text in the first place?
They're often introduced when copying text from word processors, PDFs or certain websites, which sometimes embed formatting or marker characters you can't normally see.
Does the Whitespace Visualizer have any limitations?
It's built for everyday text inspection; extremely long documents are still handled but may take a moment longer to render.
