A string obfuscator is an online tool that transforms readable text into an unreadable or encoded format. It helps hide the original content from casual viewing, but it is not encryption and does not provide true security.

This tool supports Base64, Hexadecimal, ROT13, reverse string, HTML entities, and Caesar cipher (with custom shift). Some methods are symmetric (ROT13, reverse) and others can be fully decoded using the corresponding decode mode.

No. Obfuscation merely disguises the text without a secret key. Anyone who knows the encoding method can easily reverse it. For real security, use encryption algorithms like AES with a strong password.

Switch the mode to Decode, paste the obfuscated text into the input field, and select the same method that was used for encoding. The tool will instantly show the original readable text in the output area. The Swap button can also help quickly exchange input and output fields.

Common use cases include hiding email addresses from bots, quickly encoding data for URLs, debugging, learning about encoding schemes, or making content temporarily unreadable for privacy in screenshots.
