What this tool does
Enter binary bytes containing only 0 and 1, optionally separated by whitespace. The total number of bits must be a multiple of 8. The tool converts them to UTF-8 text and reports invalid bytes or formatting.
- Supports space-delimited, newline-delimited, or fully contiguous binary per byte.
- Illegal characters, mutilated bytes, and invalid UTF-8 are not silently ignored.
- The output is always displayed as normal text and its contents are not executed.
How to use it
- Enter binary bytes.
- Click "Convert to text".
- Correct non-0/1 characters or incomplete bytes as prompted.
- Copy the decoded text.
Common uses
- Understand the binary representation of text at the byte level.
- Restore UTF-8 binary payload in debug logs.
- Verify the output of Text → Binary.

Binary → Text Features
Parses binary strictly as 8-bit bytes and decodes to readable text using UTF-8. Review the result, then copy it for use.
FAQ
Why does it have to be a multiple of 8 bits?
This tool handles bytes, and a byte always contains 8 bits.
Are spaces and newlines allowed?
Allowed, they serve as byte delimiters; other characters other than 0/1 will raise an error.
Why does Chinese need many sets of binaries?
The UTF-8 representation of Chinese characters usually consists of three bytes, each of which has 8 bits.
Will the conversion access the network?
No. Your binary text is checked and decoded only in your browser, without being uploaded.
