Hex is a base-16 representation of binary data (0-9, A-F). ASCII maps byte values to human-readable characters (letters, digits, symbols). The converter translates between the two representations.
Space-separated (48 65 6C 6C 6F), colon-separated (48:65:6C:6C:6F), no delimiter (48656C6C6F), and comma-separated. Choose the format that matches your input.
Yes. Paste hex to get ASCII, or paste ASCII text to get its hex representation. The conversion updates in real time as you type.
Bytes that don't correspond to printable ASCII characters are shown as dots (.) in the ASCII output. This helps identify binary data embedded in hex strings.
No. All conversion happens in your browser using simple byte manipulation. No data is transmitted to any server.
