Frequently Asked Questions
How does text become binary?
Each character has a numeric code (ASCII/Unicode). That number is converted to base-2 (binary) representation.
How many bits per character?
ASCII characters use 8 bits (1 byte). Unicode characters may use more bits depending on the encoding.
Does it support Unicode?
Yes. The tool handles UTF-8 encoded text including Korean, Chinese, emoji, and other Unicode characters.
