The Hex/Text converter transforms plain text into hexadecimal values and decodes hex strings back to human-readable text. Each character is represented by its hexadecimal code point value, useful for debugging, data analysis, and low-level programming tasks.

Choose from multiple output formats: space-separated hex values (48 65 6C 6C 6F), 0x-prefixed values (0x48 0x65 0x6C 0x6C 0x6F), or no separator (48656C6C6F). The decoder automatically detects the format used in the input.

This tool runs entirely in your browser with no server communication, making it suitable for inspecting encoded data, debugging binary protocols, or examining character encodings safely.

Frequently Asked Questions

What is hexadecimal text encoding?▾
Hexadecimal encoding represents each character by its numeric code point in base 16. For example, the letter 'A' has code point 65 in decimal, which is 41 in hexadecimal. This compact notation is widely used in programming and data analysis.
What separator format should I use?▾
Space-separated is the most common and readable format. The 0x prefix format is used in programming languages like C, Java, and JavaScript. No separator produces the most compact output but is harder to read.
Can this tool handle Unicode characters?▾
Yes. Each character is converted to its Unicode code point in hexadecimal. For basic ASCII characters, this produces 2-digit hex values. For extended Unicode characters like emojis, the values will be larger.
How is hex encoding different from Base64 encoding?▾
Hex encoding represents each byte as exactly two hexadecimal characters (0-9, A-F), making the output twice the size of the input. Base64 uses a 64-character alphabet and is more space-efficient, producing output about 33% larger than the input. Hex is preferred for debugging and low-level inspection because each byte maps directly to two readable characters.
