Base64 encoder

World's simplest base64 tool

This online program converts data to base64 encoding. It works with any textual, numeric, or Unicode data and encodes it to a single-line or multi-line base64 data. It can also encode several independent strings at once and return multiple base64 results (one per line). Created by encoding gurus from team Browserling.

Base64 encoder tool What is a base64 encoder?
This application works in your browser and it base64-encodes the given input values. Base-64 encoding works as follows – it converts the input data to binary data, then splits the binary sequence into groups of 6 bits, and assigns one of the characters from the base-64 alphabet to each 6-bit group. With this encoding algorithm, every 3 input bytes (24 bits) are converted into 4 groups of 6 bits that are encoded with 4 symbols. In base-64 encoding, the length of the output data (compared to input data) increases by a third. The base64 index table consists of uppercase and lowercase Latin letters (A-Z and a-z), numbers (0-9), and characters + and /. The = symbol is used as a padding character to fill the missing characters in the trailing groups when only one or two bytes are encoded. All base64 symbols are ASCII characters that can be easily transmitted over non-binary channels and stored in simple text files. There are no spaces in the base64 encoding, so all characters are displayed as a continuous string on a single line. Sometimes, it's convenient to split the encoded output data into constant-length chunks and print it on multiple lines. You can do that by enabling the "Chunked Base64" option. The chunked multi-line output data is also valid base64. If you need to encode several separate values at the same time, use the "Encode Lines Separately" option. It independently encodes each text line and outputs multiple base64 values. Base64abulous!
Base64 encoder examples Click to use
Single-line Base-64
This example converts a simple one-line string to base-64. It encodes 28 input ASCII characters to 40 output base-64 alphabet characters and prints them on the opposite line. The last two characters "==" mean that the output was padded with at least 12 bits to make the output base-64 data length evenly divisible by 4 (because every 4 base-64 characters form 3 input data bytes).

Chunked Base64
In this example, we base64-encoded a quote by Eleanor Roosevelt and printed the output data in a chunked format. We set the number of characters per line to 20 and the single input line got encoded as multiline data (which is still of course valid base64).
The purpose of life is to live it, to taste experience to the utmost, to reach out eagerly and without fear for newer and richer experience. Eleanor Roosevelt

Parallel Base64 Encoding
In this example, we enter a list of common chemical formulas as the input data. We want to simultaneously find base64 representations of each formula so we activate the "Encode Lines Separately" mode, which splits the input list into independent string items and encodes all items in parallel. In the input we had 6 formulas and in the output we get 6 base64-encoded formulas.
