Online Free Text to Hex Converter

Convert any text into its hexadecimal representation. Perfect for debugging, encoding data, or learning how computers store characters.

Pro Tip: This tool outputs one UTF-8 byte per pair of hex digits, separated by spaces (for example: 48 65 6c 6c 6f for "Hello").

Why Convert Text to Hex?

Debugging & Data Inspection

View raw byte values of text for debugging network protocols
Analyze encoded strings in databases or logs
Prepare data for hex editors or binary analysis

Education & Learning

Understand how characters map to hexadecimal values (ASCII/Unicode)
Practice hex conversion exercises
Explore binary and hexadecimal relationships

How It Works

Text is encoded as UTF-8 bytes, and each byte is written as a two-digit hexadecimal value:

Read Each Character

The text is processed character by character, including spaces and punctuation.

Worked Examples

Text inputs and expected UTF-8 hex output
Input text	Hex output	Notes
`Hi`	`48 69`	Two ASCII bytes.
`A B`	`41 20 42`	Includes the space byte `20`.
`€`	`e2 82 ac`	UTF-8 multi-byte character.

Get Character Code

Each character is converted to its numeric code point (e.g., 'A' = 65, 'a' = 97).

Convert to Hexadecimal

The code point is converted to a two‑digit hex string (e.g., 65 = 41). The final output is a continuous string of hex digits.

Best Practices

Use hex representation when you need to embed binary data in text‑based formats (JSON, XML)
For large texts, consider converting in chunks to avoid overwhelming output
Hex is case‑insensitive – choose uppercase or lowercase based on your project's convention

Common Use Cases

Encoding text for URLs (hex encoding is sometimes used in place of percent‑encoding)
Debugging binary data in network packets or files
Creating color codes (e.g., #FF5733 from RGB values)
