Text to Binary Converter
Encode any text to UTF-8 binary bytes.
Each character becomes one or more 8-bit values, because UTF-8 uses more bytes for accents, emoji and other non-ASCII characters.
How to use the Text to Binary tool
- Enter your text to binary in the fields above.
- Adjust any slider or type an exact number — the answer updates as you go.
- Copy the result and close the tab. Nothing you entered was sent anywhere.
About the Text to Binary tool
Type or paste text and get its UTF-8 byte encoding as 8-bit values, space-separated and live as you type.
Non-ASCII characters take more than one byte under UTF-8 — that is why café becomes three bytes for one accented character.
