About This Tool
Invisible Ink Text: This tool uses Unicode Zero Width Joiner (ZWJ) characters to create text that appears invisible in most applications. The hidden message can be copied and pasted elsewhere, appearing as blank space, but can be revealed by pasting back into this tool.
Note: While this method hides text from casual observation, it is not secure encryption. The hidden text can be detected by examining the raw character codes. Do not use for sensitive information.
How It Works
- Enter your secret message in the input field below
- Click "Create Invisible Text" to generate the hidden message
- Copy the result - it will appear as empty space
- Paste it where you want to hide your message (social media, documents, etc.)
- To reveal, copy the "empty" text and paste it back into the tool

Frequently Asked Questions
What is Unicode ZWJ?
The Zero Width Joiner (ZWJ) is a non-printing character in Unicode used to control the joining behavior of adjacent characters. It has no visible representation, which makes it useful for hiding text.
Where can I use invisible text?
You can use it in most applications that accept Unicode text, including social media platforms, messaging apps, documents, and more. However, some platforms may filter or remove these characters.
How secure is this method?
This is not a secure encryption method. It simply hides text from casual view. Anyone who examines the raw text or knows to look for ZWJ characters can discover your message.
Why does my invisible text sometimes show as boxes or question marks?
Some applications or fonts may display unsupported Unicode characters as replacement symbols. The text is still there but may not appear completely invisible in those cases.
