Text to Binary Converter
Convert text into 8-bit binary code and decode binary back into text, with support for Chinese and other UTF-8 multi-byte characters. Bytes are separated by spaces for easy reading.

How to Use
- Type or paste the text you want to convert into the text input box.
- Click Text to Binary and the output box shows the matching binary code, separated by spaces.
- To go the other way, enter binary code in the binary input box (8 bits per group, separated by spaces).
- Click Binary to Text to restore the original text.
- Click Copy to put the result on your clipboard.
Features
- Two-way conversion: text to binary and binary back to text.
- Every character is written out as its 8-bit ASCII binary code.
- Chinese characters are supported through UTF-8 multi-byte encoding.
- Clean output format with a space between each byte, so the result stays readable.
- Runs entirely in the browser with no network requests, so it is fast and private.
Use Cases
Teaching programming concepts
Show the binary encoding of characters directly so beginners can see how computers represent data at the lowest level.
Verifying data encoding
Check whether a particular string encodes to the binary you expect, which is handy for protocol debugging and data format validation.
Learning cryptography
Inspect the binary form of text to understand how XOR encryption and other bitwise operations actually work.
Practicing steganography
Convert a message to binary while studying LSB techniques for hiding information inside images or text.
FAQ
Can it convert Chinese characters?
Yes. Chinese characters use UTF-8 encoding, so each character maps to 3 bytes (24 bits), and the tool prints every byte in full.
Is there a required format for binary input?
Each group should be 8 bits (one byte), with a space between groups, for example: 01001000 01100101 01101100.
How is this different from hexadecimal conversion?
Binary shows every single bit as a 0 or 1, while hexadecimal packs each group of 4 bits into a digit from 0 to F. Binary is more literal but much longer; hex is more compact.
Is there a length limit?
The tool runs in your browser, so we suggest staying under about 5,000 characters per run to keep the experience smooth.
