Base64 is a two step encoding/decoding process that uses 64 bits to represent a string of data. The first step is to take the data and convert it into a string of 64 characters. The second step is to use the Base64 algorithm to turn that string into a series of bytes.
Base64 is a code that helps computers understand data. You can use the Base64 Decode tool online to decode data that has been encoded in Base64. For example, if you want to decode a picture that someone has saved as a jpeg file, you can use the Base64 Decode tool online to do it. The Base64 Decode tool will take the jpeg file and decode it so that you can see the image inside of it.
