How to use Text to Binary Converter

1
Choose a direction
Use the toggle to pick Text to Binary or Binary to Text. The swap button moves your result into the input so you can convert it back the other way.

Type or paste text, or paste a string of binary. The conversion runs automatically as you type, with full UTF-8 support for any character.
3
Pick a separator
For binary output, choose a space between each byte for readability or no separator for a continuous stream. When decoding, spaces are optional.

4
Copy the result

Frequently asked questions

How is text converted to binary?

Each character is encoded as UTF-8 bytes, and every byte is written as an 8-bit binary number. Plain English letters map to a single 8-bit group each, while accented characters, symbols, and emoji use two to four bytes, so they produce several 8-bit groups.

Does this support emoji and non-English text?

Yes. Because the tool uses UTF-8, it handles every Unicode character — accented letters, Cyrillic, Greek, Chinese, Japanese, Arabic, emoji, and more. They are encoded to the correct multi-byte sequences and decode back exactly.

What binary format does the decoder expect?

The Binary to Text decoder reads 8-bit groups. Spaces between bytes are optional, so both a continuous stream and space-separated bytes work. The total number of binary digits must be a multiple of 8, and only the digits 0 and 1 are allowed.

Why did I get a conversion error?

Decoding fails if the binary contains characters other than 0 and 1, or if the total length is not a multiple of 8 bits. Remove any stray characters and make sure each byte has exactly 8 digits, then the conversion will succeed.

Is my data uploaded to a server?

No. All conversion happens entirely in your browser. Your text is never uploaded, logged, or stored, so it stays completely private and the tool keeps working even when you are offline.
