What hex formats are accepted?

Hex input can include 0x prefixes and be separated by spaces, colons, semicolons or commas. The converter strips those and reads the remaining digits as pairs (one byte each).

Does it support Unicode?

Yes. Bytes are decoded as UTF-8 and text is encoded as UTF-8, so accented characters, non-Latin scripts and emoji all convert correctly. A multi-byte character spans several hex pairs.

Why does my hex fail to decode?

Decoding uses strict UTF-8, so a byte sequence that is not valid UTF-8 is rejected rather than producing garbage. Check that you have an even number of hex digits and that the bytes form a real UTF-8 string.

How many hex digits per character?

Each byte is two hex digits. Plain ASCII letters are one byte (two digits). Accented Latin characters are usually two bytes, and emoji are typically four bytes, so they take four, eight, or more hex digits.

Is hex the same as ASCII codes?

For plain English text, yes — each character maps to its ASCII byte written in hex, e.g. A is 41. But this tool is UTF-8 aware, so it also handles characters beyond ASCII that have no single ASCII code.

Is my input uploaded?

No. Conversion runs entirely in your browser with built-in APIs — nothing is sent to any server.

Hex to Text Converter

Hex to text converter

Convert hexadecimal byte sequences into readable UTF-8 text, or encode text into hex. It is useful for reading hex dumps, debugging protocols and data files, or producing a hex representation of a string. Hex input is forgiving — 0x prefixes plus spaces, colons, semicolons and commas are all stripped automatically before decoding.

How it works

In Hex to Text mode the tool removes separators and prefixes, splits the remaining digits into pairs, reads each pair as one byte (0–255), and decodes the whole byte array as UTF-8 using the browser’s TextDecoder in strict mode — so invalid byte sequences are flagged rather than mangled. In Text to Hex mode it runs the reverse: TextEncoder turns the text into UTF-8 bytes, and each byte is written as a two-digit, zero-padded hex value.

Example

Decoding 48 65 6c 6c 6f gives Hello:

Hex	Byte	Character
48	72	H
65	101	e
6c	108	l
6c	108	l
6f	111	o

Encoding café the other way gives 63 61 66 c3 a9 — note the é is two bytes (c3 a9) because it is outside ASCII.

Everything runs in your browser with built-in TextEncoder and TextDecoder APIs — nothing is uploaded. For other encodings, try the Base64 decoder.
