How do I convert text to binary?

Short answer

Paste your text into a browser-based text to binary converter and it turns each character into its binary code, typically eight bits per character based on its byte value. The conversion runs on your device, and a matching tool converts the binary back into readable text.

How characters become ones and zeros

Every character has a numeric code point, and that number can be written in base 2 as a string of bits. For basic ASCII letters and digits each character fits in eight bits, so the word Hi becomes two groups of eight binary digits. The converter walks your text, looks up each character's value, and writes out the binary, which is the same encoding computers use under the hood.

A learning tool, not encryption

Binary representation is reversible and offers no secrecy at all, so it is useful for teaching how text is stored, for puzzles and CTF challenges, and for understanding character encodings, not for hiding anything. The reverse converter reads groups of bits and reconstructs the characters, which lets you check your work or decode a binary string someone sent you.

Step by step

  1. Paste your text. Paste the text you want to convert into the tool.
  2. Convert locally. The tool turns each character into binary in your browser.
  3. Copy or reverse. Copy the binary output, or use the binary to text tool to convert it back.

Frequently asked questions

How many bits per character?

Basic ASCII characters use eight bits each. Characters outside ASCII use their multi-byte encoding, so they take more bits.

Can I convert binary back to text?

Yes. A companion binary to text tool reads the bits and reconstructs the original characters.

Is binary a form of encryption?

No. It is a plain representation that anyone can reverse, so it provides no secrecy.
