Text to Binary Converter

About this tool

Convert any text into 8-bit binary, one byte per character. Each letter becomes its ASCII value in binary.

Example

Input: Hi

Output: 01001000 01101001

How to use

Paste or type your text into the box above, then read or copy the result. Everything runs privately in your browser, your text is never uploaded to a server.

How to use this tool

1. Type or paste plain text into the input box.
2. Choose the option to convert text to binary.
3. Review the 8-bit binary output shown for each character.
4. Copy the binary result if you need to reuse it elsewhere.

Step by step, what happens

1. The tool reads your text one character at a time, including spaces and punctuation.
2. Each character is converted to its ASCII value and then displayed as an 8-bit binary byte.
3. The tool keeps the bytes in character order, so the output matches the original text exactly.
4. If your input includes unsupported characters, their binary form depends on how the tool handles encoding, so plain ASCII text is the safest choice.

Worked example

Here is what happens when you convert a short greeting with a space and punctuation.

Input: Hi!

1. The tool takes H, then i, then ! as separate characters.
2. It converts each character to its 8-bit ASCII binary form.
3. The three bytes are shown in the same order as the input.

Tips and common mistakes

• Use plain text if you want the most predictable ASCII output.
• Remember that spaces are converted too, so they appear as their own binary byte.
• Each character becomes one 8-bit group, so the output length grows quickly with longer text.
• If you need to compare results, keep the exact same capitalization because uppercase and lowercase letters have different binary values.
