What is Binary?
Binary is a base-2 number system using only two digits: 0 and 1. Computers use binary to store and process all information because electronic circuits can easily represent two states (on/off, true/false, high/low).
Each binary digit is called a "bit". Eight bits make up one "byte", which can represent a single character, number, or symbol.
How Binary Encoding Works
Each character is converted to its ASCII/UTF-8 value, then represented as an 8-bit binary number:
| Character | ASCII | Binary |
|---|---|---|
| A | 65 | 01000001 |
| B | 66 | 01000010 |
| a | 97 | 01100001 |
| 0 | 48 | 00110000 |
| ! | 33 | 00100001 |
How to Use Binary Encoder
To Encode (Text → Binary):
- Select the "Text → Binary" tab
- Type or paste your text in the input area
- View the binary output instantly
- Copy the result using the Copy button
To Decode (Binary → Text):
- Select the "Binary → Text" tab
- Paste your binary code (spaces are optional)
- View the decoded text instantly
- Copy the result using the Copy button
FAQs About Binary Encoder/Decoder
What format should binary input be in?
Binary should be groups of 8 digits (0s and 1s). Spaces between bytes are optional.
Can I decode any binary?
The binary must be valid 8-bit sequences. Invalid patterns will show an error message.
Is my data secure?
Yes! All processing happens locally in your browser. We never see or store your data.
What's the difference between ASCII and UTF-8?
ASCII covers basic English characters (0-127). UTF-8 is backwards compatible with ASCII but supports all Unicode characters.
