unicode to utf-8 converter

world's simplest unicode tool

This online utility encodes Unicode data to UTF-8 encoding. Anything that you paste or enter in the input area automatically gets converted to UTF-8 and is printed in the output area. It supports all Unicode symbols and it works with emoji characters. You can choose binary, octal, decimal, or hexadecimal output base for UTF-8 bytes or set an arbitrary base. You can also adjust the delimiter between the bytes and add a byte prefix. Created by encoding gurus from team Browserling.

What is a unicode to utf-8 converter?

This browser-based utility converts your Unicode text to UTF-8 encoding. UTF stands for Unicode Transformation Format and it's the most popular Unicode encoding in the world. The number "8" in UTF-8 means that 8-bit numbers (single-byte numbers) are used in the encoding. To convert your input to UTF-8, this tool splits the input data into individual graphemes (letters, numbers, emojis, and special Unicode symbols), then it extracts code points of all graphemes, and then turns them into UTF-8 byte values in the specified base. UTF-8 uses the following rules to encode the data. If the code point value is less than 128, then it's the same value is used as the output byte value. If the code point is greater than 127, then it's turned into a sequence of two, three, or four bytes, where each byte of the sequence is between 128 and 255. You can easily switch between the four most popular bases for the UTF-8 bytes. Namely, you can choose to output UTF-8 as binary, octal, decimal, or hexadecimal numbers. If you need any other base, then you can select the "Custom Base" option and specify the required base value in the field below it. This utility supports bases up to 36. If you need to output UTF-8 in base-64, then use our Unicode to base-64 converter. You can also adjust the delimiter that's used between the bytes in the output data. By default, it's the space character but you can set it to any other symbol. There are two more useful features that we have added. One of them lets you improve the appearance of bytes by padding short values with zeros to achieve a full byte length. Binary values get padded to eight bits, octal values to three symbols, and hex values to two symbols. The other option lets you add a prefix in front of bytes. In binary, the prefix "0b" is added, in octal, the prefix "o" is added, and in hexadecimal, the prefix "0x" is added.

Napoleon Bonaparte's Quote

This example converts a Napoleon Bonaparte's quote to UTF8 bytes in radix of 8 (octal). The quote is written in bold-italic Unicode letters and the output is UTF8 encoding of these letters. It uses a space character between the octets and adds zeros in front of smaller bytes so that they are all 3 characters long.

Special Unicode Symbols

In this example, we convert four interesting Unicode characters to UTF8-encoded binary bytes. We add a prefix "0b" in front of the binary values to make it unambiguous that the base is binary and pad some of them with zeros to achieve the length of 8 characters.

Bakery Emojis in Base-21

In this example, we select a custom base from the output base dropdown and enter the value 21 in the custom base field. We then load a list of Unicode bakery products emoji as the input and UTF-8 encode them. We also use a dash symbol to separate base-21 output bytes.
