This browser-based utility converts Unicode text to base-16 hexadecimal data. Anything that you paste or enter in the text area on the left automatically gets printed as hex on the right. It supports the most popular Unicode encodings (such as UTF-8, UTF-16, UCS-2, UTF-32, and UCS-4) and it works with emoji characters. You can also customize the hexadecimal output format by enabling hex prefixing, padding and spacing. Created by encoding gurus from team Browserling.
This utility converts your input Unicode data into base-16 code points and then prints them one by one in the encoding you have chosen. Base-16 (also known as radix-16) is called the hexadecimal format, or simply the hex format. The hex format is made out of 16 symbols that consist of 0-9 and a-f (sometimes A-F). Before printing the hex code points, they are converted to one of nine encodings that we have added. They are – UTF8 that uses two to eight hex digits, then UTF-16-LE, UTF-16-BE, UCS-2-LE, and UCS-2-BE that use four or eight hex digits, then UTF-32-LE, UTF-32-BE, UCS-4-LE, and UCS-4-BE that use the maximum amount of storage, which is eight hex digits. For use in programming, you can add the prefix "0x" before hex values. For better output formatting, you can put a single space character between each hexadecimal value, as well as pad bytes that are an odd number hex characters in length with an additional zero to make all bytes an even length. For multibyte encodings, such as UTF-16, UCS-2, UTF-32, and UCS-4, you can also add the Byte Order Mark (BOM) endianness indicator. BOM for UTF-16-LE is 0xfffe, for UTF-16-BE it's 0xfeff, for UTF-32-LE it's 0xfffe0000, and for UTF-32-BE it's 0x0000feff.
This example converts a couple of fantastic Unicode emoji creatures into the hexadecimal format. Before printing them to output, each emoji is encoded as UTF8. For convenience, we have added a prefix "0x" and separated all hexadecimal numbers with a single space.
In this example, we convert the famous Latin phrase by Julius Caesar – "Veni, vidi, vici" – to hex base and UCS2-BE encoding. This phrase means "I came, I saw, I conquered". We prefix all hex digits with a "0x", pad them with zeros and separate with spaces. We also prefix the output hex stream with UCS2-BE's BOM, which is 0xfeff.
In this example, we convert the grumpy dancing Unicode cat man into the hexadecimal radix. We use the least effective output encoding UCS-4-LE (which is the same as UTF-32-LE). This encoding uses eight hex digits per one code point. From other options, we've only selected the padding option, which means that we get a merged hexadecimal number where all code points follow one another as eight-digit zero-padded hex sequences.
