Hex to ASCII Converter - Decode Hexadecimal Text

Hex to ASCII Converter

The Hex to ASCII Converter helps you read text represented by hexadecimal values. Use it to inspect a field from a log or trace, then compare the result with the source format.

How Hex Values Map to Characters

Hex uses digits 0-9 and letters A-F. Two hex digits can represent a byte: 48 maps to H, and 65 maps to e. A sequence such as 48 65 6C 6C 6F can carry readable text.

Worked Example

• Hex input: 48 65 6C 6C 6F
• Decoded text: Hello

The pairs map as follows: 48 to H, 65 to e, 6C to l, 6C to l, and 6F to o. The shorter forms 48 65 6C and 48656C represent the same bytes with different spacing.

How to Decode Hex

1. Paste your values into Hexadecimal Input.
2. Remove labels or prefixes such as 0x if the input is not accepted.
3. Review ASCII Text Output and use Copy.

Check Input Formatting and Encoding

Spaced notation such as 48 69 and continuous notation such as 4869 represent the same bytes. Check which form the input accepts. Letter case does not change a hex value: 6C and 6c are equivalent.

Each byte needs two digits. Check for incomplete pairs, invalid characters, or a remaining 0x prefix. Not every byte represents printable ASCII, and non-ASCII text depends on its character encoding. Do not assume arbitrary binary data will become a readable message.
