Hex to ASCII Converter

📖 How to Use

Select conversion direction (Hex→ASCII or ASCII→Hex), paste your content, and click 'Convert'. Hex input supports space-separated, unseparated, or 0x-prefixed formats with auto-detection.

⚡ How It Works

Hex→ASCII decodes every two hex characters into one ASCII character. ASCII→Hex converts each character to a two-digit hex representation. Uses String.fromCharCode() and charCodeAt() with parseInt() for bidirectional conversion.

💼 Use Cases

View hex content of binary files and network packets; debug network protocols; learn computer encoding concepts; handle embedded system debug output; analyze data encoding.
