How much does base64 encoding increase size?

Base64 encodes each set of three bytes into four bytes. In addition the output is padded to always be a multiple of four. So, for a 16kB array, the base-64 representation will be ceil(16*1024/3)*4 = 21848 bytes long ~= 21.8kB. A rough approximation would be that the size of the data is increased to 4/3 of the original. Jan 18, 2011

How does base64 encode work?

Base64 encoding takes the original binary data and operates on it by dividing it into tokens of three bytes. A byte consists of eight bits, so Base64 takes 24bits in total. These 3 bytes are then converted into four printable characters from the ASCII standard.

What is the difference between encoding and encryption?

Summary. Encoding is for maintaining data usability and can be reversed by employing the same algorithm that encoded the content, i.e. no key is used. Encryption is for maintaining data confidentiality and requires the use of a key (kept secret) in order to return to plaintext. May 7, 2019
