Base64 Decode Online Tool

Base64 Decode Online Tool is a free online tool that allows you to decode Base64 encoded text.


It can be used to decode Base64 encoded text that has been encoded using the Base64 encoding scheme.


Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding. Each Base64 character represents exactly 6 bits of data. Three 8-bit bytes (i.e., a total of 24 bits) can therefore be represented by four 6-bit Base64 characters.




How to Decode Base64?

There are a few ways to decode Base64. One way is to use an online Base64 decoder, such as this one from Base64 Decode.


To decode Base64, first look at the encoding table to determine the value of each character. Then, convert each character into its Base64 value. Finally, add up all of the Base64 values to get the original message.


Here is an example of how to decode Base64:

Original message: Hello world!

Encoding table:

  • H: 72
  • e: 101
  • l: 108
  • o: 111

Base64 values:

72 + 101 + 108 + 111 = 392


Original message: Hello world!

How base64 decode works

Base64 decode works by taking a string of characters and converting them into a byte array. The byte array is then converted into a base64 string.


To decode a base64 string, the first step is to convert the string into a byte array. This is done by taking each character in the string and converting it into its ASCII code. The ASCII code is then converted into a base64 byte.


Once the byte array has been created, it is then converted into a base64 string. This is done by taking each byte in the array and converting it into a character. The characters are then put together to form the base64 string.
