Binary Decoder / Encoder
Translate human-readable ASCII text into machine binary code (0s and 1s), or instantly decode binary strings back into plain text.
💻 What is Binary Code?
Binary is the foundational language of all modern computers and electronics. It consists entirely of two numbers: 0 and 1. These numbers represent the two states of an electrical switch (off and on).
Because computers don’t understand letters like “A” or “B”, every character you type is translated into a unique 8-digit combination of 0s and 1s, called a “Byte”.
🔄 How does this tool work?
This tool uses the standard ASCII (American Standard Code for Information Interchange) and UTF-8 encoding formats.
When you type text, it instantly converts each character into its numerical decimal value, and then converts that decimal into base-2 (binary). It works seamlessly in reverse to decipher secret binary messages back into readable text.
