String Hex Converter
Convert between strings and hexadecimal, supports multiple encoding formats
What is Hexadecimal?
Hexadecimal (Hex) is a base-16 number system that uses digits 0-9 and letters A-F to represent values. In computers, it's commonly used to represent binary data because each hexadecimal digit corresponds to 4 binary bits.
Encoding Format Comparison
UTF-8 is variable-length encoding that supports all Unicode characters; UTF-16 uses 2 or 4 bytes to represent characters; ASCII only supports 128 basic characters. Choosing the appropriate encoding format is important for data compatibility.
Application Scenarios
Hex encoding is commonly used in network protocols, data transmission, file formats, encryption algorithms and other scenarios. It's more readable than binary while accurately representing byte data.
Important Notes
Hex encoding is not encryption, it's just a data representation method. Converting between different encoding formats may cause garbled text. Pay attention to encoding format selection when handling non-ASCII characters.
