Output

Convert Plain Text to Hexadecimal (Base-16) Online

Encode standard English text or international characters into standard base-16 hexadecimal bytes. Our free online Text to Hex Encoder is built to assist developers, systems programmers, and computer science students in formatting hex payloads, debugging serial data connections, or testing bit-level configurations.

Character Encodings and Hexadecimal Bytes

Every character you type into a text editor is represented as a number internally. Standard ASCII maps English characters to numbers from 0 to 127. For example, the character 'H' is represented by code 72. In base-16, 72 is written as the hex value 48. This tool automates this process for any text string.

How to Convert Text to Hex (Step-by-Step)

  1. Character Isolation: Read the input text character by character.
  2. Get Code Point: Get the decimal character code (ASCII/Unicode) of the character (e.g. A becomes 65).
  3. Convert to base-16: Convert the decimal value to its base-16 hex representation (e.g. 65 to 41).
  4. Join: Combine the hex tokens together using your preferred character separator (like spaces or commas).

Flexible Formatting

Format your hex output with standard prefixes (0x), toggle between UPPERCASE/lowercase casing, and choose custom character separators.

ASCII & UTF-8

Decodes character values safely using standard browser character mappings, supporting standard alphanumeric text.

100% Client-Side

Calculations run locally inside your browser, providing maximum security for private data.

Frequently Asked Questions (FAQ)

Text to hex encoding works by retrieving the decimal character code (ASCII or Unicode UTF-8) for each character in the input string, and then converting that decimal integer into its equivalent 2-digit base-16 hexadecimal representation. For example, the character 'A' corresponds to decimal 65, which converts to the hex value 41.
Developers convert text to hex because hexadecimal is a compact, standardized way to represent raw byte values. It is widely used in network communication payloads, URL encoding parameter definitions, binary file signatures (magic bytes), and hex-based cryptography keys.
Yes, your text is completely secure. The script operates entirely client-side using JavaScript running in your local browser sandbox. No input strings, converted hex values, or logs are transmitted to external servers.
