What is Text to Binary?

Computers store text as binary. Converting by hand past two characters is tedious and error-prone.

Paste your text and see the binary code instantly.

If you're teaching encoding, you show how 'A' becomes 01000001. If you're building escape-room puzzles, you encode hints as binary. If you're debugging, you check character-level encoding fast.

How to use Text to Binary

Four steps. No setup, no signup.

  1. Step 1

    Paste your text

  2. Step 2

    See the 8-bit binary output

  3. Step 3

    Compare letters to their codes

  4. Step 4

    Hit Copy and use the binary

Example

A 2-letter word becomes its 8-bit binary.

Input

Hi

Output

01001000 01101001

Why Text to Binary is useful

  • ✓

    Teach or learn how characters map to ASCII binary.

  • ✓

    Encode hints for escape rooms or puzzle games.

  • ✓

    Verify character-level encoding when debugging.

  • ✓

    Round-trip with the Binary to Text tool to check accuracy.

Common questions

How does the conversion work?

Each character maps to its 8-bit ASCII code.

Tip: 'A' is 01000001, 'a' is 01100001.

What about Unicode?

ASCII chars convert to 8 bits. Unicode emojis can take 16-32 bits.

Tip: Stick to standard text for clean output.

Can I convert back?

Yes, use the Binary to Text converter.

Tip: Test round-trip to verify accuracy.

Why are bytes separated by spaces?

Standard format for readability. Each 8-bit chunk is one character.

Tip: Toggle to remove spaces for compact form.
