๐ Understanding Text Obfuscation
Text obfuscation is a security technique that makes text unreadable to automated systems (bots, scrapers, AI) while keeping it perfectly readable for humans. It's essential for protecting sensitive information published online.
Obfuscation Techniques:
- Unicode Substitution - Replaces characters with visually identical Unicode alternatives from different alphabets (Latin, Cyrillic, Greek)
- Invisible Characters - Inserts zero-width spaces and invisible Unicode characters that break pattern recognition
- Homoglyphs - Uses look-alike characters that appear identical but have different Unicode values (a vs ะฐ vs ฮฑ)
- Spacing Variations - Replaces normal spaces with different Unicode space types (em space, en space, thin space)
- Direction Markers - Adds RTL/LTR directional markers that confuse text parsers
- Zalgo Text - Adds diacritical marks and combining characters for visual distortion
Common Use Cases:
- Email Protection - Prevent spam harvesters from scraping email addresses from your website
- Phone Number Privacy - Hide phone numbers from automated scrapers and telemarketing lists
- Social Media - Evade content detection and censorship systems on platforms
- Contact Forms - Protect published contact information while keeping it accessible to humans
- Documentation - Secure sensitive data in publicly accessible documents
- Anti-Scraping - Prevent AI systems from harvesting your content for training data
Best Practices:
- Use appropriate protection levels - higher isn't always better
- Test obfuscated text in your target environment
- Combine multiple techniques for stronger protection
- Save custom presets for consistent branding
- Update obfuscation periodically as bots evolve
- Consider accessibility - some screen readers may struggle with heavy obfuscation

โ Frequently Asked Questions
Text obfuscation is the process of making text unreadable to bots and automated systems while keeping it perfectly readable for humans. You need it to protect email addresses from spam harvesters, hide phone numbers from scrapers, protect personal data on websites and prevent AI systems from easily parsing your content. Our tool uses Unicode techniques including homoglyphs, invisible characters and character substitution.
Unicode obfuscation replaces normal characters with visually identical Unicode alternatives (homoglyphs), inserts zero-width invisible characters between letters, uses different Unicode space types and applies directional markers. For example, the letter 'a' can be replaced with 'ะฐ' (Cyrillic), 'ฮฑ' (Greek) or 'ษ' (Latin). To humans these look identical, but to bots they're completely different characters, breaking pattern recognition.
Obfuscated text displays correctly in most modern applications including web browsers, word processors and messaging apps. However, some techniques like invisible characters may be stripped by certain systems. For maximum compatibility, use the 'Low' or 'Medium' protection levels. The 'Email Protection' preset is specifically optimized for web publishing.
No, that's the point! Obfuscated text breaks search functionality for bots and scrapers. For example, if you obfuscate '[email protected]', bots searching for email patterns won't find it. However, humans can still read and manually copy the text. This makes it perfect for protecting published contact information.
Low: Subtle protection for general content. Medium: Balanced protection for most use cases (recommended). High: Strong protection for sensitive data. Extreme: Maximum security for highly sensitive information. Use presets for specific scenarios: 'Email Protection' for emails, 'Phone Number' for phones, 'Social Media' for posts that need to evade detection.
Absolutely! All text obfuscation happens locally in your browser using JavaScript. No data is ever transmitted to our servers or any third party. You can use this tool completely offline. Your emails, phone numbers and sensitive data remain 100% private and never leave your device.
