It just converts the raw binary data into character encoding, so it doesn’t matter what the source is (image, video, database file, etc). The source binary data is taken 6 bits at a time, then this group of 6 bits is mapped to one of 64 unique characters.
The decoding process is just the reverse of that: mapping the data back to binary form.
