FAQ

What is hexadecimal?

Hexadecimal is a base-16 number system using 0-9 and A-F. It's commonly used in computing as a compact representation of binary data, where each hex digit corresponds to 4 binary bits.

What is ASCII?

ASCII (American Standard Code for Information Interchange) uses 7-bit numbers (0-127) to represent English letters, digits, punctuation, and control characters.

Why does hex to ASCII show garbled text?

If hex values exceed the ASCII range (0-127) or the input format is incorrect, the result may show garbled or non-printable characters. Ensure your hex values are in the valid range.

Does it support UTF-8?

This tool primarily handles ASCII characters. UTF-8 multi-byte characters require hex representation of each byte. The tool supports raw byte-level conversion.
