Formula

How the text and binary works
- Step oneChoose Text to binary or Binary to text.
- Step twoType or paste the input. Binary can be separated by spaces.
- Step threeCopy the result. Each character becomes one or more groups of 8 bits.
What this tool does not do
- It writes the UTF-8 bytes of the text, not 7-bit ASCII or another character set.
- It does not compress or encrypt anything.
- Binary to text needs complete groups of 8 digits.
Frequently asked questions
Why do some characters give more than 8 bits?
Plain English letters fit in one byte. Other characters, such as the euro sign, use 2 to 4 bytes in UTF-8, so they show as 2 to 4 groups of 8 bits.
What if my binary has the wrong length?
Binary text needs a multiple of 8 digits. The tool tells you how many digits it found.
Is this ASCII?
For English letters, digits and common symbols the result is the same as ASCII. The tool also handles other languages through UTF-8.
