Convert text to hex and back instantly — perfect for developers
Hexadecimal (hex) is a base-16 number system using digits 0-9 and letters A-F. It's widely used in computing because four binary digits (bits) map perfectly to one hexadecimal digit. When you convert text to hexadecimal, each character is first converted to its ASCII code, then represented as a two-digit hex value. For example, the letter "A" has ASCII value 65, which is 41 in hexadecimal.
Hexadecimal is essential in web development for color codes (like #FF5733), memory addresses in system programming, and data representation in network protocols. Developers use hex extensively when debugging, viewing binary data, or working with low-level hardware. Understanding hexadecimal is fundamental for anyone working with computers at a technical level.
This converter handles bidirectional conversion between text and hexadecimal. For text-to-hex, each character is converted to its ASCII value and then to its two-digit hexadecimal representation. For hex-to-text, the reverse process occurs. All processing is instant and happens entirely in your browser without sending data to any server.

You can enter hex as continuous digits (414243) or space-separated pairs (41 42 43). The converter handles both formats automatically.
Yes, both work. Hexadecimal A-F can be uppercase (A-F) or lowercase (a-f). The converter handles both seamlessly.
In web development, colors are often represented as six hex digits, like #FF5733 where FF is red, 57 is green, and 33 is blue intensity.
