Binary Converter

Convert text to binary and binary back to text.


    

ToolsSoup's Binary Converter is a free online tool that turns any text into its binary representation and converts binary digits back into readable text, instantly and entirely in your browser. Type a message to see the 1s and 0s behind every character, or paste a string of binary to decode it into words — with no uploads, no sign-up, and nothing ever leaving your device.

What is binary?

Binary is the base-2 number system that computers use to store and process all data. Instead of the ten digits we use in everyday decimal numbers, binary uses only two: 0 and 1. Each digit is called a bit, and eight bits make a byte. Text is stored as bytes using an encoding such as UTF-8, so the letter H becomes the byte 01001000 (decimal 72) and a lowercase i becomes 01101001 (decimal 105). Converting between text and binary lets you see exactly how a string is represented at the lowest level.

How to convert text to binary online

Converting with ToolsSoup takes just a few seconds:

  1. Type or paste your text — or a string of binary bytes — into the input box.
  2. Click Text to Binary to turn each character into its 8-bit binary code, or Binary to Text to turn binary back into characters.
  3. Copy the result with one click and paste it wherever you need it.

What format does the binary use?

When converting text to binary, the tool encodes your text as UTF-8 and writes each byte as an 8-bit group padded with leading zeros, separating the bytes with single spaces — for example, Hi becomes 01001000 01101001. When converting binary back to text, separate the bytes with spaces or new lines; each group must contain only the digits 0 and 1 and be at most eight bits long, so any other token is reported as an error.

Why use this binary converter?

  • 100% free with no ads, sign-up, or usage limits.
  • Runs entirely in your browser — your text is never uploaded to a server.
  • Converts text to space-separated 8-bit binary bytes and back again.
  • Handles UTF-8, so accented letters, symbols, and emoji work too.
  • Works offline once the page has loaded.

Frequently asked questions

Is this binary converter free?

Yes. Every tool on ToolsSoup is completely free to use, with no account, sign-up, or hidden limits.

Is my data safe?

Absolutely. All conversion happens locally in your browser using JavaScript, so your text is never sent to or stored on any server.

What binary format does it output?

Text to Binary encodes your text as UTF-8 and outputs each byte as an 8-bit group with leading zeros, separated by single spaces — for example 01001000 01100101 01101100 01101100 01101111 for the word Hello. This is the most common and most readable way to write binary text.

How should I separate bytes when decoding?

When converting binary back to text you can separate the bytes with spaces or line breaks — for example 01001000 01101001 decodes to Hi. Each group must contain only 0s and 1s and be at most eight bits long; any other token is reported as an invalid binary byte.

Does it handle characters beyond standard ASCII?

Yes. The converter uses UTF-8 encoding, so characters outside the basic ASCII range — such as accented letters, non-Latin scripts, symbols, and emoji — are encoded as multiple bytes and restored to the exact original text when decoded.
