Text to Binary, Octal & Hex Converter

Workflow & Usage

1. Enter your text or encoded values in the left textarea.
2. Use the Encode / Decode toggle inside the input area to switch direction.
3. Select the desired format:
   • Binary (8-bit)
   • Octal
   • Hexadecimal
4. Optional controls:
   • Batch by newline — process one value per line
   • Trim lines — ignore extra whitespace in batch mode
5. View the result instantly on the right and copy with one click.

Invalid or malformed input is handled per line so one error won’t stop the entire batch.

Encoding Formats Explained

Binary (8-bit)

Each byte is represented using eight bits.

Example:

Hello → 01001000 01100101 01101100 01101100 01101111

Octal

Each byte is displayed using base-8 notation.

Example:

Hello → 110 145 154 154 157

Hexadecimal

Each byte is displayed using base-16 notation.

Example:

Hello → 48 65 6c 6c 6f

Common Use Cases

• Learning how text is represented in binary
• Debugging encoding issues
• Inspecting byte-level data
• Educational demonstrations
• Working with low-level protocols and formats

---

Tips & Best Practices

• Binary output uses 8-bit bytes separated by spaces.
• Hexadecimal output is lowercase and space-separated.
• Use batch mode when converting multiple strings.
• This tool supports UTF-8, so non-ASCII characters may use multiple bytes.

How It Works

• Input text is encoded as UTF-8 bytes
• Bytes are converted into the selected representation
• Decoding reverses the mapping back to text
• Each line is processed independently
• All logic runs locally in real time
