Hexadecimal Encoder & Decoder

Hexadecimal (Base 16) is a positional numeral system with a radix of 16. It uses sixteen distinct symbols: 0-9 to represent values zero to nine, and A-F to represent values ten to fifteen. It is widely used in computer science because it is much more compact than binary (one hex digit represents 4 bits) and easier for humans to read. This tool converts text characters into their Hex byte values.

Frequently Asked Questions

Why use Hex instead of Binary?

Readability. A single Byte like '10101100' is hard to remember. In Hex, it's just 'AC'. It compresses the visual length by 4x, making it the standard for viewing raw data.

Is case important in Hex?

Usually, no. 'AC', 'ac', 'Ac' all represent the same value (172). Our decoder handles both cases, and the encoder typically outputs uppercase for clarity.

How does it handle Emojis?

Since we use UTF-8, an emoji like 🌟 will turn into its 4-byte sequence: 'F0 9F 8C 9F'. Each pair of hex characters represents one byte.
