Zero Text

🕵️ Zero-width text steganography generator

• ✅ Convert any content (including CJK characters and emoji) to zero-width characters
• ✅ Embed encrypted messages into normal host text (appears completely normal)
• ✅ One-click decryption to extract hidden messages
• ✅ Auto-paste, copy button, and bidirectional interaction
• ✅ Pure frontend implementation, no data upload, safe and reliable

Install

git clone https://github.com/tlyboy/zero-text.git

Usage

pnpm installpnpm devpnpm build

Encrypt & Embed

1. Enter the text you want to hide (e.g., my password is 123456)
2. Enter a normal-looking "host text" (e.g., Hello, how are you today?)
3. Click the Encrypt & Embed button
4. The tool inserts zero-width characters into the host text, producing text that looks completely normal

Decrypt & Extract

1. Paste the text containing hidden information into the "Decrypt Input" area
2. Click Decrypt & Extract
3. The tool will recover the originally hidden text

Technical Implementation

• Uses the following Unicode characters:
  • \u200B (zero-width space) to represent 0
  • \u200C (zero-width non-joiner) to represent 1
• Original text -> UTF-8 -> binary -> zero-width characters -> inserted into host text
• Decryption reverses the above process
• All encryption / decryption operations are performed locally in the browser with no data stored or uploaded
