This tool converts text into its binary representation (the 0s and 1s computers actually store) and converts binary back into readable text. It supports full UTF-8, so any character converts correctly, all in your browser.
How to use it
- Type or paste your text or binary.
- Choose the direction.
- The converted result appears instantly.
- Copy it.
About Text to Binary Converter
Every character a computer stores is ultimately binary. Seeing that representation is useful for learning how text encoding works, for puzzles and CTF challenges, or for debugging low-level data. This converter turns each character into its binary byte sequence and can reverse the process, decoding binary back into text. It handles Unicode through UTF-8, so emoji and non-Latin scripts round-trip cleanly. Everything is computed in your browser.
FAQ
What does each group of digits mean?
Each group of 8 bits (a byte) represents one part of a character’s UTF-8 encoding.
Does it support emoji and accents?
Yes. It encodes through UTF-8, so all Unicode characters convert correctly.
How is text converted to binary?
Each character is mapped to its character code (usually UTF-8 or ASCII) and that number is written in base 2. For example, the letter A is code 65, which is 01000001 in 8-bit binary.
