Binary to Text Converter and Text to Binary Converter
Our binary to text converter turns strings of 0s and 1s into readable words, and it works the other way too. Paste your code or type a message and the result appears as you type. It handles accents, symbols and emoji, and it also reads hex, decimal and octal.
How to Use the Binary to Text Converter
Paste binary code into the left box and the text appears below it. Groups of 8 digits are the standard, and you can separate them with spaces, commas or new lines. If you paste one long string with no gaps, the tool splits it into groups of 8 from the left.
- A group shorter than 8 digits is read as a plain number
- Anything that is not a valid digit stops the conversion with a message
The note under the result tells you how many bytes were read and how many characters came out. A wrong digit or a bad group length is named in plain words, so you can fix it quickly. Press Copy text to take the result with you.
Text to Binary Converter
Type or paste text into the right box to use it as a text to binary converter. Every character is turned into one or more bytes, and each byte is written as 8 binary digits. Pick a separator for the output, then press Copy code to take it with you.
Below the boxes, the text to binary converter shows a breakdown table. It lists each character with its Unicode code point and its bytes, so you can see exactly where the digits come from. The table shows the first 40 characters and the output still covers the full text.
How Binary Becomes Text
Computers store every character as a number. A standard table such as ASCII gives each letter, digit and symbol its own number, and the number is stored in binary. The letter H is 72, which is 01001000 in a single byte.
| Character | Decimal | Binary |
| H | 72 | 01001000 |
| e | 101 | 01100101 |
| l | 108 | 01101100 |
| o | 111 | 01101111 |
Binary spelled out for the word Hello reads 01001000 01100101 01101100 01101100 01101111. Uppercase and lowercase letters differ by one bit, which is why A is 01000001 and a is 01100001. Both rows come straight from the ASCII table.
Binary to ASCII and UTF-8
ASCII covers 128 characters, such as English letters, digits and common symbols. Many online pages that show binary to ASCII stop there, and they fail on anything else. This binary to text converter uses UTF-8, which keeps ASCII exactly as it is and adds every other character.
In UTF-8 a character takes between one and four bytes. The letter é uses two bytes, the euro sign uses three and the emoji for a grinning face uses four. Paste 11100010 10000010 10101100 and you get the euro sign. If the bytes do not form valid UTF-8, the tool shows the replacement character and says so.
Reading Binary by Hand
You can decode a byte without any tool. Write the place values 128, 64, 32, 16, 8, 4, 2 and 1 above the digits, then add the values that sit above a 1. For 01001000 the 1s sit under 64 and 8, so the sum is 72, and the ASCII table says 72 is H.
Repeat the steps for each group and read the letters in order. Long messages take time, which is why a binary translator saves effort. Use the text to binary converter to check your own work after a few groups.
Hex, Decimal and Octal
The number system menu changes how the binary to text converter writes bytes. Hexadecimal uses two digits per byte, so Hello becomes 48 65 6C 6C 6F. Decimal gives 72 101 108 108 111, and octal gives 110 145 154 154 157.
Switching the menu rewrites the left box in the new system when the old content was valid, so your example stays usable. Hex is the usual choice for programmers who read memory dumps. A decimal group above 255 is rejected, because one byte cannot hold it.
Fixing Common Errors
- A group with 7 or 9 digits, usually from a missed space
- A letter or digit 2 in a binary string
- Text copied from a PDF with hidden line breaks
- Binary saved in another encoding such as Latin 1
Wrong output with odd symbols usually points to the encoding. If the original text was saved as Latin 1, a character such as é is one byte that UTF-8 cannot read, so you see the replacement character. The text to binary converter shows the true bytes of any text, which gives you something to compare against. Try the same bytes again after checking the source.
Where a Binary Translator Helps
Students use the tool to see how a computer stores a name. Puzzle makers hide clues in binary, and capture the flag events often include strings of 0s and 1s. Developers read bytes from a log or a protocol and need the matching text quickly.
The binary to text converter does not read files or images. It works on text you paste, and everything stays in your browser. Nothing is uploaded.
Convert Your Binary Now
Paste the code, pick a separator and read the answer. The binary to text converter is free and needs no account. Come back to the text to binary converter whenever you need to write a message in 0s and 1s.
Frequently asked questions
How does a binary to text converter work?
It reads each group as a number, then looks that number up as a character.
Does the text to binary converter support emoji?
Yes, it uses UTF-8, so emoji become four bytes.
Why do I get strange symbols?
The bytes are probably in another encoding or contain a wrong group.
Can I convert without spaces?
Yes, a long string is split into groups of 8 digits.
Is my text uploaded anywhere?
No, the conversion runs in your browser.
How many bits are in a byte?
Eight bits make one byte.
