Text ↔ Binary / Hex

About This Tool

The Text to Binary Converter encodes and decodes text using binary (base 2) or hexadecimal (base 16) representation. Each character is converted using its ASCII/Unicode code point.

Binary output uses 8 bits per character, space-separated for readability. Hex output uses 2 hex digits per character. All conversion runs in your browser.

How to Use

1. Select the conversion direction using the mode tabs at the top.
2. Select the encoding format: Binary or Hex.
3. Type or paste your input text (or binary/hex for decoding).
4. Click Convert to generate the output.
5. Click Copy to copy the result to your clipboard.

Use Cases

Computer science students learn binary representations of ASCII characters. Developers debug byte-level data by converting strings to hex. Security analysts decode binary-encoded messages in CTF challenges.

FAQ

• Does it support Unicode (non-ASCII characters)? — Yes. The tool uses JavaScript's charCodeAt() which returns the Unicode code point, not just the ASCII value.
• What delimiter separates binary groups? — Binary groups (one per character) are separated by spaces. When decoding, space-separated 8-bit groups are accepted.
• What is the difference between binary and hex output? — Binary uses base 2 (only 0s and 1s, 8 digits per char); hex uses base 16 (0–9, A–F, 2 digits per char). Hex is more compact.
