Text to Binary Converter
Encode text into UTF-8 binary bytes and decode binary strings back into readable text, with full Unicode support.
Encoding and decoding use UTF-8 and run locally — accents and emoji are handled correctly.
One Character Is Not Always One Byte
For plain English text, each character maps to one byte and the binary output matches ASCII/UTF-8 exactly. Accented characters, emoji and non-Latin scripts take 2–4 bytes in UTF-8, so the binary string grows accordingly — "ñ" is 2 bytes (11000011 10110001), not one. This is correct UTF-8 behavior, not an error, and it is why two tools can disagree on the "length" of the same string.
How the Transformation Works
- Type text to see every character encoded as 8-bit binary bytes via UTF-8.
- Paste space-separated binary groups to decode them back into text.
- Accented characters and emoji encode as multiple bytes — the decoder reassembles them correctly.
- Copy either representation with one click.
Example Input & Output
Common Questions
Is binary the same as ASCII?
ASCII covers 128 characters in one byte each. UTF-8 is a superset that encodes every Unicode character, so this tool handles both plain ASCII text and full Unicode.
How must binary input be formatted?
As space-separated groups of up to 8 bits each. The decoder ignores stray whitespace.
