Unicode base64 encoder

World's simplest unicode tool

This browser-based utility converts Unicode data to base64. Anything that you paste or enter in the text area on the left automatically gets encoded to base64 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 adjust the output base64 line length. Created by encoding gurus from team Browserling.

Unicode Encoding
Use this Unicode encoding for the conversion.
Before converting Unicode input to base-64, the input is first encoded in this encoding, and only then is converted to base-64.
Base64 Format
Cut base64 into several parts, with the specified length.
Indicate the length of one part. (Number of characters per line).
Don't cut base64 into parts, and display all content in one line.
Unicode base64 encoder tool What is a unicode base64 encoder?
This utility converts your Unicode letters, numbers, symbols, emojis, and other characters to base64 encoding. Base64 is a data encoding standard that uses only 64 ASCII symbols. It lets you share your data on systems that don't understand Unicode. The information encoded in base64 is represented by a set of bytes using 52 Latin characters and 10 numbers – A-Z, a-z, 0-9, and 2 additional symbols – "/" and "=". In base64, every 3 bytes of data are encoded as 4 characters. If only one or two bytes are encoded, then the "=" sign is used as the fill character at the end so that there were 4 characters in the output. Encoding your Unicode data to base64 is a two-step process. First, as Unicode can be stored in computer memory in many different ways, it's encoded to bytes in the encoding format that you have chosen. We support UTF8, UTF16, UTF32, UCS2, and UCS4 encoding formats, as well as Big Endian and Little Endian byte order formats for the multi-byte formats (UTF16, UCS2, UTF32, and UCS4). This series of bytes is then fed to base64 encoding algorithm that produces the base64 output. Also, to make it easier to share base64 data, you can cut the output into multiple parts of the specified length.
Unicode base64 encoder examples Click to use
Duke Ellington Quote
In this example, we convert a Duke Ellington's quote to UTF-8 encoding and then convert the UTF-8 bytes to base64 ASCII output. We also limit the number of characters per line to 24 symbols.

Unicode Bear
Roar! In this example, we draw a bear's face entirely with Unicode characters and turn it into base64 encoding. We use a UTF-32 Little Endian (LE) encoding for Unicode characters here and output only 4 characters per line (3 bytes per line).

Unicode Sweets Emojis
This example encodes a list of sweet emoji to the base64, using a UCS-2 Big Endian (BE) encoding. UCS-2-BE is almost the same as UTF-16-BE with the only difference that it can represent less Unicode characters. This example doesn't cut the output into pieces and displays all the base64 characters in one continuous line.
