About This Tool

Invisibly conceal sensitive messages within innocent carrier text or image pixels without raising suspicion.

Supports Zero-Width Unicode steganography (hiding secret binary strings between innocent words using invisible zero-width spaces that survive Twitter, Discord, and Slack copy-paste) and Image Canvas LSB steganography (embedding secret bytes into pixel color channels).

All concealment and extraction processes run 100% locally in your browser memory with zero network uploads.

Key Features

  • Zero-Width Unicode Hiding: Conceal secret text inside everyday plain text completely invisibly using zero-width Unicode characters.
  • Image LSB Steganography: Embed secret text into the least significant bits of image pixels with zero visible distortion.
  • Bidirectional Encode & Decode: Easily encode secret payloads or extract hidden messages from suspicious text and images.
  • 100% Client-Side Privacy: No text or images ever leave your device or get sent to remote servers.

Frequently Asked Questions

How does Zero-Width text steganography work?
The Unicode standard defines characters with zero visual width, such as zero-width space (U+200B) and zero-width non-joiner (U+200C). This tool translates your secret message into binary bits and represents 0s and 1s with these invisible characters, hiding them directly inside normal words.
Why does image steganography require lossless PNG format?
Lossy compression formats like JPEG alter pixel color values slightly when saving, which destroys the delicate least significant bits holding your hidden message. PNG uses lossless compression, preserving every bit accurately.
Are my images or secret messages uploaded anywhere?
No. All pixel modifications and Unicode insertions occur entirely in your local browser memory using the HTML5 Canvas API.
