All obfuscation is done client-side. Your data never leaves your browser.
Obfuscate strings using 8 different encoding methods simultaneously: hex encoding, binary, unicode escapes, HTML entities, URL encoding, base64, reverse string, and ROT13. Each result is displayed with a copy button for easy use.
Developers frequently need to encode or obfuscate strings for various purposes like escaping data for different formats, generating test data, or understanding how encoding works across different systems.
Web developers, security researchers, CTF players, and anyone who needs to convert text between different encoding formats quickly.
Type or paste the text you want to obfuscate into the Input Text area
All 8 obfuscation methods are computed and displayed simultaneously
Click the Copy button next to any result to copy the obfuscated text to your clipboard
The description badge next to each method shows a preview of what the output looks like
Results update in real-time as you type in the input field
Input: "Hello, World!" → Base64: SGVsbG8sIFdvcmxkIQ==Input: "<script>" → HTML Entities: <script>Input: "password" → ROT13: cebjqrfNo, base64 is an encoding scheme, not encryption. Anyone can decode base64-encoded text trivially.
ROT13 is mainly used for hiding spoilers or in CTF challenges. It provides zero real security.
URL encoding can vary based on what characters are encoded. This tool encodes all non-alphanumeric characters for safety.
HTML entities are interpreted by browsers in HTML context, not in JavaScript strings. Use unicode escapes (\uXXXX) for JavaScript.
