Encoding Conversion

What are encoding conversion tools?

Encoding conversion tools convert data between different representations and are commonly used in web development, API debugging, text processing, log analysis, data exchange, and software development.

Different encoding formats solve different problems. Base64 represents binary data as text, URL encoding handles special characters in URL parameters, Unicode and character encodings describe the relationship between characters and bytes, JSON escaping handles special characters inside JSON strings, and number base conversion changes how numeric values are represented.

What encoding conversion tools are available?

This category provides common online encoding and data representation tools. Choose a tool according to the type of data you need to process.

Base64, URL, Unicode, and character encoding

  • Base64: Encode and decode Base64 and Base64URL data for text and binary data representation.
  • URL: Encode and decode Chinese characters, spaces, and special characters in URL parameters.
  • Unicode: View Unicode representations and process Unicode escape sequences.
  • Character encoding: Convert between UTF-8, GBK, GB2312, UTF-16, and other character encodings to help diagnose text encoding problems.

JSON escaping and unescaping

JSON escaping handles quotation marks, backslashes, line breaks, and other special characters inside JSON strings. When one JSON document needs to be stored as a string inside another JSON document, the inner special characters must be escaped correctly to prevent parsing errors or changes to the data structure.

Binary, octal, decimal, and hexadecimal conversion

Number base conversion changes an integer from one numerical representation to another. Binary is commonly used for bitwise operations, octal is often used for Linux file permissions, decimal is used for everyday numerical values, and hexadecimal is common for color values, memory addresses, hash values, and protocol data.

What is the difference between encoding and encryption?

Encoding mainly solves data representation, transmission, and compatibility problems. Encoded data can normally be restored using the corresponding decoding method. For example, Base64 is not an encryption algorithm because its encoded content can be decoded by anyone who knows the encoding rules.

Encryption uses cryptographic algorithms and keys to protect data confidentiality. Sensitive data, passwords, and authentication information should not use Base64 or other encoding methods as a substitute for encryption.

Which encoding tool should you use?

  • For Base64 strings, use a Base64 encoder or decoder.
  • For URL parameters, use a URL encoder or decoder.
  • For Unicode code points or Unicode escape sequences, use a Unicode conversion tool.
  • For UTF-8, GBK, or other character encoding problems, use a character encoding conversion tool.
  • For placing JSON inside another JSON string, use a JSON escape or unescape tool.
  • For converting numeric values between binary, octal, decimal, and hexadecimal, use a number base converter.

Where are encoding conversion tools used?

Encoding conversion tools are useful for web development, API debugging, interface parameter analysis, log troubleshooting, database data inspection, text processing, and software testing. For example, Chinese characters in a URL parameter may be represented using percent-encoded sequences. A URL decoder can restore the original text for inspection. When Chinese text appears corrupted, the character encoding, such as UTF-8 or GBK, should be checked separately.

Does encoding conversion provide encryption?

No. Encoding can generally be reversed using the corresponding rules and is intended for data representation and transmission. Encryption relies on cryptographic algorithms and keys to protect confidentiality. Therefore Base64, URL encoding, Unicode escaping, HTML entities, and hexadecimal representation should not be used as security mechanisms for sensitive information.
