ASCII to Hex Converter

ASCII (American Standard Code for Information Interchange) uses 7 bits to represent 128 characters including English letters, digits, and symbols. Unicode is a superset that extends ASCII to support over 140,000 characters from virtually every writing system in the world. All ASCII characters have the same code points in Unicode.

Switch to the "Hex to ASCII" tab, paste your hex string (with or without spaces, e.g. "48656C6C6F" or "48 65 6C 6C 6F"), and the tool will instantly convert it back to readable ASCII text. It handles both uppercase and lowercase hex digits.

Printable ASCII characters range from hex 20 (space) to hex 7E (tilde ~). This includes uppercase letters (41-5A), lowercase letters (61-7A), digits (30-39), and common symbols. Values below 20 are control characters, and 7F is the delete character.

Yes, the tool handles all standard ASCII characters including spaces (hex 20), tabs, and printable symbols. For characters outside the ASCII range (like emoji or accented letters), the tool shows the Unicode code point in hex, decimal, and binary.

Hex representation is used extensively in programming for debugging (viewing raw bytes), network protocols (HTTP headers, URLs), color codes (#FF0000), escape sequences (\x41 for 'A'), file format analysis, and cryptography. It's more compact than binary and easier to read than decimal for byte-level work.
