Text that appears blank but contains hidden data using zero-width Unicode characters (like U+200B) or CSS tricks (e.g., white-on-white).
How does it work?
Zero-Width: Each character is encoded into bits, then represented by invisible Unicode characters. CSS Hidden: Text is styled to be invisible (e.g., opacity 0.01). Combined: Both methods used together.
Is it safe?
Yes, but only for fun, testing, or education. Hidden text can be detected and decoded easily. Not secure for privacy.
Where can I use it?
In social media bios, messages (Discord, WhatsApp), or to test detection tools. Not for spam or deception.
