Base64 is a binary-to-text encoding that uses 64 printable characters to represent each 6-bit segment of a sequence of byte values. As for all binary-to-text encodings, Base64 encoding enables transmitting binary data on a communication channel that only supports text.
When comparing the original data to the resulting encoded data, Base64 encoding increases the size by 33% plus about 4% additional if inserting line breaks for typical line length.
