Hex to Text Converter — Decode or Encode Hexadecimal
Paste hex bytes (space-separated or continuous) to decode them into readable text, or type any string to encode it as hexadecimal — perfect for debugging protocols, reading binary files or understanding character encodings.
Direction
How does this calculator work?
Each two-digit hex pair represents one byte. Paste your hex string (spaces optional) and the decoder converts the byte sequence to UTF-8 text. For text-to-hex, each character is UTF-8 encoded and each byte written as two hex digits.
Formula
How this is calculated
Hexadecimal (base-16) is a compact way to represent binary data: each byte is written as exactly two hex digits (00–FF), giving values from 0 to 255. The converter strips spaces and optional 0x prefixes, splits the remaining string into two-character chunks, and parses each as a base-16 number to obtain the raw byte sequence.
The byte array is then decoded using the UTF-8 standard, which maps byte patterns to Unicode characters. A single ASCII character maps to one byte (e.g. "A" = 0x41 = 65). Non-ASCII characters like accented letters or emoji may be represented by 2–4 bytes in UTF-8, so the byte count can exceed the character count. If a sequence is not valid UTF-8, the converter falls back to interpreting each byte as a Latin-1 character code.
For text-to-hex conversion the process is reversed: the string is encoded to UTF-8 bytes, and each byte is formatted as a zero-padded two-digit hex pair. The output is shown with spaces for readability and as a continuous string.
Frequently asked questions
Emoji and many non-ASCII characters are encoded in UTF-8 as 2, 3 or 4 bytes. For example, "😀" encodes to 4 bytes: F0 9F 98 80. The byte count shows the total bytes, not the number of visible characters.
No. You can enter continuous hex (e.g. 48656c6c6f) or space-separated pairs (48 65 6c 6c 6f) — both formats are accepted. The 0x prefix on individual bytes is also stripped automatically.
Hex is used everywhere in computing: colour codes (#FF5733), memory addresses, network packet dumps, cryptographic hashes, binary file editors (hex editors), and low-level protocol analysis. It is easier to read than binary while still being directly translatable to bytes.
