What is ASCII?

ASCII (American Standard Code for Information Interchange) is the 7-bit character encoding that assigns every English letter, digit, punctuation mark and control code a number from 0 to 127 — for example A is 65 and a is 97. It is the foundation that UTF-8 and almost every modern text format build on. The Convert ASCII to Base64 works directly with these ASCII codes.
