Text to Binary Converter
Encode text as UTF-8 bytes and show every byte as exactly eight bits. One visible character can produce several bytes.
Conversion runs only in this browser. Input and output are not uploaded.
Input size: 0 B.
How this converter works
Text is encoded to UTF-8 bytes, and every byte is formatted as exactly eight binary digits.
- A single space separates bytes by default.
- No-separator and custom literal separator modes are available.
- The byte count refers to UTF-8, not visible characters.
Frequently asked questions
Is this 7-bit ASCII?
No. This generic text route uses complete eight-bit UTF-8 bytes.
Why is emoji long?
Emoji normally require several UTF-8 bytes, and each byte uses eight bits.
Using this tool
Encode text as UTF-8 binary bytes
Encode text as complete eight-bit UTF-8 groups with a space, no separator, or a custom literal separator.
Input and output
Example: `Hi` becomes `01001000 01101001`.
Important behaviour
The byte count reflects UTF-8, so an accented character or emoji can use multiple eight-bit groups.
Keep in mind
This route does not output Unicode code points or 7-bit ASCII groups.
Conversion is performed in the browser. Copying or downloading happens only when you choose those actions.
