About Text & Binary Converter
Convert text to Binary and vice versa.
The tool is designed to process data in the browser unless the interface explicitly states that a network request is required.
How to use this tool
- Enter or select the text, binary, bits value you want to work with.
- Review the available settings, then run the convert action.
- Review the text, binary output and use the copy or download action when the tool provides one.
What you can do with Text & Binary Converter
- Convert text to binary
- Decode binary text
What this conversion does
Convert text to 8-bit binary and binary back to text using UTF-8, one byte per space-separated group.
Example input
HiExample output
01001000 01101001Practical workflow
- Choose Text to Binary or Binary to Text.
- Paste the value — for decoding, groups of 0s and 1s with or without spaces.
- Click Convert, then Copy the output or Swap to feed the result back as input.
Common use cases
- Check how a character is stored as bytes when learning about encodings.
- Decode a binary message from a puzzle, CTF challenge, or classroom exercise.
- Verify the UTF-8 bytes of accented letters or emoji when debugging encoding issues.
Important notes and limitations
- Text is encoded with the browser's TextEncoder as UTF-8, so a character outside ASCII produces two to four bytes rather than one.
- Decoding strips all whitespace first; the remaining digits must contain only 0 and 1 and their count must be a multiple of 8.
- Everything runs locally in the browser; the last input and mode are kept in local storage for convenience.

- Number Base Converter — convert a number, rather than text, between binary, decimal, and hex.
Frequently asked questions
Why does one letter become eight digits?
Each byte is written as eight bits. The letter A is byte 65, which is 01000001 in binary.
Why does an emoji produce four groups?
The tool uses UTF-8, where characters above U+FFFF take four bytes. Accented Latin letters take two bytes and most Asian scripts take three.
Why do I see “Binary string length must be a multiple of 8”?
After removing spaces the digit count did not divide evenly into bytes — a digit is missing or extra. Check the group boundaries.
Can I convert a number like 42 to binary here?
This tool converts the characters “4” and “2” to their UTF-8 bytes. To convert the numeric value 42 to 101010 use the Number Base Converter.
