What is Text to Hex Conversion?

Text to hex conversion transforms readable text into hexadecimal notation (base-16). Each character is converted to its ASCII or Unicode value, then represented as a two-digit hex number. For example, the letter "H" (ASCII 72) converts to 48 in hexadecimal. Hex is commonly used in programming, memory dumps, color codes, and data inspection.

Frequently Asked Questions

How does text to hex conversion work?

Each character in your text is converted to its ASCII or Unicode numeric value, then that decimal number is expressed in hexadecimal (base-16) format using digits 0-9 and letters A-F.

What's the difference between uppercase and lowercase hex?

They're functionally identical - it's just a formatting preference. "4A" and "4a" represent the same value. Choose uppercase for better readability or lowercase to match common coding conventions.
