Convert Text to Binary
What is Convert Text to Binary
This tool converts plain text into binary code, the sequence of 0s and 1s that computers use to represent every character. Each character is converted to its underlying byte value and shown as an 8-digit binary group, with groups separated by spaces. The converter is UTF-8 aware, so multi-byte characters such as emoji or accented letters correctly produce more than one 8-bit group.
How to use
- Type or paste your text in the input box.
- Watch the binary output update instantly as you type.
- Click Copy to copy the binary code to your clipboard.
- Use the Share button to get a link with your text pre-filled.
When to use it
Learning how computers store text under the hood? Type Hi and you get 01001000 01101001, the exact byte values ASCII assigns to H and i. It's useful for computer science homework, decoding a byte dump while debugging, or building a puzzle that hides a message in plain-looking binary.
Frequently asked questions
Why does each character produce 8 digits?
Each character is stored as one byte, and a byte is 8 bits, so every group of 0s and 1s in the output represents one character using values from 00000000 to 11111111.
Does it support emoji and accented characters?
Yes. The converter is UTF-8 aware, so characters outside the basic ASCII range, such as é, ñ, or emoji like 😀, are encoded as their full UTF-8 byte sequence and appear as two, three, or four 8-bit groups instead of one.
Can I convert the binary back to text?
Yes. Use the companion Binary to Text Converter, linked below the converter.
Can I share this tool with my inputs pre-filled?
Yes. The URL updates automatically as you type. Copy it from the address bar or use the Share button, anyone who opens the link will see your exact inputs ready to go.
Why is there a space between each group of 8 digits?
The spaces mark where one character's byte ends and the next begins, which makes the output easier to read and copy. The Binary to Text Converter accepts both spaced and unspaced binary, so removing the spaces still works when decoding.
