Binary to Text

About this tool

Converts binary back into text. Paste groups of 0s and 1s separated by spaces, with each group of up to 8 bits standing for one byte, or one unspaced string whose length is a multiple of 8. The bytes are decoded as UTF-8, so the output of Text to Binary round-trips exactly, including accented letters, euro signs and emoji. If something is not binary, for example another character or a group longer than 8 digits, or the bytes are not valid UTF-8, the tool shows an error message instead of guessing. Conversion happens in your browser as you type.

How to use it

1. Paste your binary, such as 01001000 01101001 (or 0100100001101001).
2. Read the decoded text in the output, or the error message if the input is not valid.
3. Copy the result.

Example

01001000 01101001

Hi

Common problems

The tool shows an error

The input contains something other than 0 and 1 and spaces, a group is longer than 8 digits, or the bytes do not form valid UTF-8. The message names the first bad group.

I pasted one long string of bits

It must be a multiple of 8 digits long; it is split into bytes automatically. Otherwise add a space after every 8 digits.

Accented letters come out wrong

They need all of their UTF-8 bytes (two or more groups). Make sure none were lost when copying.
