Text Encoder/Decoder

Convert text between various encoding formats commonly used in web development, cybersecurity, and data transmission. This tool supports Base64, URL, Form URL Encoded (application/x-www-form-urlencoded), HTML Entities, Hex, Binary, Base32, Base58/62, ROT13, Morse Code, ASCII, Unicode Escape, and Punycode encodings.

Typical Use Cases

Text encoding and decoding is essential for various applications in web development, data transmission, and cybersecurity. Base64 encoding is commonly used for transmitting binary data in environments that only support text, such as email attachments or embedding images in HTML/CSS. URL encoding ensures special characters are properly transmitted in URLs, while Form URL Encoded format is specifically used for HTML form submissions. HTML entity encoding prevents XSS attacks by safely displaying HTML characters.

Developers use hex and binary encodings for low-level data representation and debugging. Base32 is useful when case sensitivity is an issue, and Base58/62 is popular in cryptocurrency for creating human-readable addresses. ROT13 provides simple text obfuscation, while Morse code conversion has historical and educational value. ASCII and Unicode escape encodings help with character set compatibility issues, and Punycode enables international domain names to work within the limitations of DNS.

Encoding Methods

  • Base64: Encodes binary data to ASCII string format using 64 characters
  • URL: Replaces special characters with % followed by hexadecimal digits
  • Form URL Encoded: Similar to URL encoding but used for HTML forms (application/x-www-form-urlencoded), converts spaces to + instead of %20
  • HTML Entities: Converts characters to their HTML entity representation
  • Hex: Represents each character as its hexadecimal value
  • Binary: Converts characters to their binary (base-2) representation
  • Base32: Similar to Base64 but uses a 32-character subset of ASCII
  • Base58/62: Encoding formats that avoid visually ambiguous characters
  • ROT13: Simple substitution cipher that replaces each letter with the letter 13 positions after it
  • Morse Code: Represents characters using dots and dashes
  • ASCII: Converts text to/from ASCII code values
  • Unicode Escape: Represents Unicode characters as \uXXXX sequences
  • Punycode: Encoding used to convert Unicode to ASCII for domain names
