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 Flip ASCII Bits works directly with these ASCII codes.
The Flip ASCII Bits runs entirely in your browser. You enter your text or codes, the transformation happens locally on your device, and the result appears instantly — there is no upload and nothing to install, so your data stays completely private.
Developers use the Flip ASCII Bits to debug data, inspect bytes and prepare test fixtures; students use it to learn how character encoding works; hobbyists use it for ASCII art and retro computing. It pairs well with the related ASCII tools below.
