Otherwise, let me know and I will try to help you.

I hope that you managed to get the right encoding result. As you can see, this is a very simple process and you can encode text to Base64 even by hand. To summarize, you learned that encoding “ABC” to Base64 yields the result “QUJD”. The final chord, concatenate all letters to get the Base64 string: QUJD So, matching indexes, convert them to corresponding letters: For complete list, see Base64 Characters Table. It starts with the letter “A” in alphabetical order (i.e., A=0, B=1, C=2, D=3, and so on). They are easy to remember, because it is a zero-based numbering, where each index corresponds to a Latin letter. Integer numbers obtained in the previous step are called “Base64 indices”. If you did everything right, each group will be transformed into its integer number as follows: There you have to convert each group from binary to decimal by finding its corresponding decimal value in the ASCII table. To do this, prepend the prefix “00” (two zeros) in front of each group: Well and good, now you have 4 groups:Īt this step you have to convert six-bit bytes into eight-bit bytes. Then, divide the resulting string into groups so that each one has 6 characters (if the last group has less than 6 characters, you need to fill it with zeros until it reaches the desired length). Now concatenate all the binary values together (that is, glue all the groups along and make sure you get a total of 24 characters): 010000010100001001000011 Thus, now you have 3 groups of ones and zeros: To do this, for each letter you need to find the corresponding binary value in the ASCII table. Next you need to convert each group to binary.

To understand how the encoding algorithm works, check the example below that describes step by step how to manually encode strings to Base64 (if you are looking for an automatic converter, use the Base64 online encoder).įor example, you have the “ABC” string and want to convert it to Base64:įirst, you need to split the string letter by letter. Technically, it can be said that it converts eight-bit bytes into six-bit bytes. The Base64 encode algorithm converts any data into plain text.
