Text to Binary Translator
Convert text to binary and binary back to text in one click. Fast, UTF-8 ready, and 100% private in your browser.
How to Convert Text to Binary
Paste or Type Your Text
Drop your text into the left box. The binary appears on the right the moment you start typing, so there is no button to press.
Read the Binary Output
Each character shows as an eight-bit byte, grouped with spaces so it stays readable. The counter shows the exact bit count.
Switch or Swap Direction
Click Binary to Text to decode instead, or hit the swap button to flip the two boxes and reverse the conversion.
Copy or Download
Use the copy button to grab the result, or download it as a .txt file to keep.
How Text Becomes Binary
Computers do not store letters. They store numbers, and every number is a run of ones and zeros called binary. When you type the letter A, your computer looks up its character code, 65, and writes it as eight bits: 01000001. A text to binary translator does that lookup for every character in your text and lines the results up for you.
This tool converts text to binary using standard UTF-8, the same encoding the web runs on. Plain English letters take one byte each, which is eight bits, while accented letters, symbols, and emoji take two to four bytes. That is why cafe with an accent is longer in binary than plain cafe, and why a single emoji can be 32 bits on its own. Switch to binary to text and the tool reverses the process, reading each byte back into the character it stands for.
People convert text to binary for a few reasons: learning how encoding works in a computer science class, checking what bytes a string really produces, building puzzles and geocaching clues, or just seeing a message in raw machine form. Whatever the reason, every conversion here runs in your browser. Nothing you type is uploaded, stored, or logged.

Frequently Asked Questions
Common questions about converting text to binary.
What is text to binary?
Text to binary is the process of turning readable characters into the ones and zeros a computer actually stores. Each character maps to a number, and that number is written as bits. The word Hi becomes 01001000 01101001, which is two eight-bit bytes, one for each letter.
How do you convert text to binary?
To convert text to binary, take each character, find its character code, and write that code in base 2 padded to eight bits. The letter A is code 65, which is 01000001. This tool does that for a whole string at once, instantly, as you type.
How is a letter represented in binary?
A letter is represented by its character code written as eight bits, which is one byte. Capital A is 01000001 and lowercase a is 01100001. That eight-bit pattern is the number for the character in the ASCII and UTF-8 tables.
Is binary the same as ASCII?
No. ASCII is a table that maps characters to numbers, while binary is how any number is written in ones and zeros. ASCII says A is 65, and binary writes 65 as 01000001. This tool uses UTF-8, which extends ASCII to cover every language and emoji.
How many bits are in one character?
A basic English character uses eight bits, which is one byte. Characters outside plain ASCII use more: many accented letters take 16 bits, and most emoji take 32 bits, because UTF-8 stretches to two, three, or four bytes for them.
Is this text to binary translator free and private?
Yes. This text to binary translator is completely free with no signup and no limits. Every conversion runs in your browser on your own device, so nothing you type is uploaded or logged. It even keeps working offline once the page has loaded.
