How Binary Encoding Works
Binary (base-2) represents data using only two digits: 0 and 1.
Each character is converted into its byte representation (typically 8 bits).
UTF-8 encoding ensures multi-byte characters are handled correctly.
Spaces and formatting in binary input are automatically removed during decoding.
Frequently Asked Questions
Q.What is binary encoding?
A. Binary uses only 0s and 1s (base-2) to represent data. Each character is converted to its byte representation, typically 8 bits.
Q.Can I encode special characters and emojis?
A. Yes. Full UTF-8 support means all Unicode characters — including Korean, Chinese, emojis, and symbols — work perfectly.
Q.How many bits are in each character?
A. Each character typically becomes 8 bits (1 byte). For example, 'A' becomes '01000001'.
Q.Is binary encoding secure?
A. Binary is just a number‐system representation, not encryption. Use proper encryption (AES, RSA) if you need security.
