Binary to Text Converter

Convert binary to plain text and plain text to binary. Text is read as UTF-8, so emoji and accented letters convert correctly, and you can space out the bytes or keep the bits unbroken. Everything runs in your browser, so your text stays on your device.

About converting binary and text

What does a binary converter do?

Computers store every letter and symbol as a group of 0s and 1s called bits. This tool moves between the two forms. It can turn plain text into the binary a computer sees, and turn a string of 0s and 1s back into readable text. Each character maps to 8 bits (one byte), and the text is read as UTF-8 so non-English characters and emoji survive the round trip. Everything happens in one click.

Binary to text converter options

Text to binary

Turns plain text into binary. Each character is read as a UTF-8 byte and written as 8 bits, so emoji and accented letters convert correctly.

Binary to text

Turns binary back into plain text. Bits can be grouped with spaces or run together, and stray line breaks are ignored.

Space between bytes

Puts a space after every 8 bits so the binary is easier to read. Turn it off for one unbroken run of bits with no spaces.

How to convert text to binary by hand

Every character has a number. For plain English letters it is the ASCII code: A is 65, a is 97, and a space is 32. To write that number in binary, use the place values 128, 64, 32, 16, 8, 4, 2, and 1, and put a 1 under each value you need to add up to the number.

CharacterNumberAdds up fromBinary
H7264 + 801001000
i10564 + 32 + 8 + 101101001

So Hi in binary is 01001000 01101001. To go the other way, add up the place values under each 1 and look up the character for that number. Letters outside plain English take more than one byte in UTF-8: é is 11000011 10101001 and the emoji 😀 is four bytes long.

These are the 8 bit binary codes for every English letter. Capitals and lowercase differ by a single bit, the third from the left.

When to convert binary and text

Binary shows up whenever you look at how text is stored under the hood. Here are the most common reasons people use a binary converter:

  • ·Learning how computers store text. Type a word and watch it become the exact 0s and 1s a computer keeps in memory.
  • ·Homework and CS classes. Check your answers when a class asks you to encode a word into binary or decode a string of bits.
  • ·Puzzles and escape rooms. Decode a hidden message written in 0s and 1s, or hide one of your own.
  • ·Debugging and low-level work. Spot-check how a specific character maps to its byte when working with encodings.
  • ·Fun and profile bios. Drop a short message in binary into a post, bio, or message for effect.

Frequently asked questions

What is binary?
Binary is a way to write data using only two digits, 0 and 1. Computers store every letter, number, and symbol as a group of these bits. Text is usually stored 8 bits at a time, and each 8-bit group (a byte) stands for one character.
How do I convert text to binary?
Make sure Text to binary is selected, then type or paste your text into the input box and click Convert to binary. The binary result appears below. Click the copy button to copy it, or download it as a .txt file.
How do I convert binary to text?
Click Binary to text, paste your 0s and 1s into the input box, then click Convert to text. The original text appears below. The bits can be grouped with spaces or run together, and line breaks are ignored.
Does it handle emoji and accented characters?
Yes. The text is read as UTF-8 before it is turned into binary, so emoji, accents, and other non-English characters survive a round trip through convert to binary and back without getting corrupted.
Why do I get an error when converting binary to text?
The input has to be made only of 0s and 1s, grouped into full sets of 8 bits (with or without spaces between them). If it contains other characters or the total number of bits is not a multiple of 8, the tool cannot line the bits up into bytes and shows an error.
Is the binary to text converter free?
Yes, it's completely free with no signup, no limits, and no watermarks. Use it as often as you like.
Is my text safe and private?
Your text never leaves your browser. All processing runs locally on your device, so nothing is uploaded to a server. Once the page has loaded you can even use it offline.
