Binary Text Translator
Translate text into binary code and decode binary back into readable text in an instant.
100% in-browser · no data sent
Each character is encoded as 8-bit UTF-8 bytes, so everything from plain ASCII to accents and emoji round-trips perfectly. Great for learning how computers store text, coding exercises, and puzzles.

How to Use
- 1 Choose a direction — select "Text → Binary" to encode or "Binary → Text" to decode.
- 2 Enter your content in the input area — the result appears in real-time as you type.
- 3 Adjust the format — toggle "Space between bytes" to group the binary into readable 8-bit chunks.
- 4 Copy or swap — use Copy to save the output, or Swap to reverse input and output.
Frequently Asked Questions
How is text converted to binary?
Each character is encoded as one or more bytes using UTF-8, and each byte is written as 8 binary digits (bits). For example, the letter "H" is byte 72, which is 01001000 in binary. Characters outside basic ASCII — like accents or emoji — use multiple bytes.
Does this support emoji and non-English characters?
Yes. The translator uses UTF-8 encoding, so accented letters (é, ñ), non-Latin scripts, and emoji (😀) all convert to binary and decode back correctly. An emoji simply uses four bytes (32 bits) instead of one.
What format should binary input be in?
Enter 0s and 1s in groups of 8 bits (one byte per character). Spaces between bytes are optional and ignored, so "01001000 01101001" and "0100100001101001" both decode to "Hi". The total number of bits must be a multiple of 8.
Why do I get an error decoding binary?
Two things cause an error: characters other than 0 and 1 in the input, or a bit count that is not a multiple of 8 (each character needs a full 8-bit byte). Remove any stray characters and make sure every byte has exactly eight digits.
