Frequently Asked Questions
What is the difference between ASCII and UTF-8 encoding?
ASCII uses 7 bits per character and supports 128 characters (English letters, digits, basic punctuation). UTF-8 uses variable-length encoding (1-4 bytes) and supports all Unicode characters including Chinese, emoji, and special symbols. Choose ASCII for simple English text and UTF-8 for international content.
What are 8-bit and 16-bit padding?
8-bit padding represents each character as exactly 8 binary digits (one byte), which is standard for ASCII. 16-bit padding uses 16 digits per character, which can represent Unicode code points directly. Use 8-bit for ASCII text and 16-bit when working with Unicode characters.
How do I change the binary separator?
Use the separator dropdown to choose between space (default), no separator, or a custom character. The separator is placed between each binary byte group, making the output easier to read or matching your target format requirements.
Can I convert binary back to text?
Yes. Switch to the Binary to Text mode using the toggle, paste your binary string, and the tool will decode it back to readable text. Make sure to use the same encoding and separator settings as when you encoded it.
What formats does the binary output use?
The output uses standard binary notation with 0s and 1s. Each character is converted to its binary representation with optional padding. The default format is 8-bit groups separated by spaces, such as 01001000 01100101 for 'He'.
