Hex to Text Converter

How to use

1. 1Pick a direction: Hex to text or Text to hex. Use Swap and use the result to chain a round trip.
2. 2For Hex to text, paste your hex digits. Spaces, commas, colons, semicolons, newlines, 0x prefixes, and \x escapes are all accepted by default; switch on Strict mode if you want to reject unexpected characters instead of ignoring them.
3. 3For Text to hex, type or paste any text (including emoji) and pick an output format on the right: Space-separated, Continuous, Colon-separated, Comma-separated, 0x array, \x escapes, or Hex dump.
4. 4Toggle Uppercase hex if you need A-F in the output instead of a-f.
5. 5Read the live result and the per-character or per-byte breakdown table, then click Copy hex or Copy text to grab the converted output.

About this tool

Hex to Text Converter turns hexadecimal byte sequences into readable text and converts text back into hex, with full Unicode support. Encoding runs your input through TextEncoder so each character is rendered as the exact UTF-8 bytes a computer would store: ASCII letters fit in a single byte (one hex pair), while emoji and non-Latin characters span 2 to 4 bytes (2 to 4 hex pairs). Output is available in seven formats, ready to paste anywhere you need it: continuous (48656c6c6f), space-separated (48 65 6c 6c 6f), colon-separated for MAC-style strings (48:65:6c:6c:6f), comma-separated for spreadsheets, a 0x array for C, Go, Rust, and JavaScript source code (0x48, 0x65, 0x6c), backslash-x escapes for shell and Python strings (\x48\x65\x6c), and a classic hex dump with 8-digit offsets and an ASCII gutter on the right. Decoding is forgiving by design: paste hex pairs separated by spaces, commas, colons, semicolons, or newlines, paste an array literal with 0x prefixes, paste a string with \x escapes, or paste a continuous run of digits, and the tool strips noise, validates each pair as a 0 to 255 byte, and reassembles them as UTF-8. A strict mode rejects unexpected characters instead of ignoring them, useful when you want to verify that an input is well-formed. Uppercase or lowercase output is one click away. A per-character breakdown table on the encode side shows code points, byte counts, hex, decimal, and binary side by side, and a per-byte breakdown on the decode side shows the index, hex, decimal, binary, and printable ASCII for each byte, so you can spot a single off-by-one byte without scrolling. Useful for debugging serial and network traffic, inspecting binary files, decoding hex strings from log files or stack traces, converting between formats expected by APIs, embedded systems, and protocols, prepping byte arrays for source code, and any time you have raw bytes in hex but need to read them as text or vice versa. Everything runs locally on your device, so the strings, log lines, captures, and snippets you paste here never leave the browser tab.
