Text to Binary Converter
Convert text to binary representation and binary back to text.
About Text to Binary Converter
This free online tool converts text to its binary representation and vice versa. Each character is converted to its 8-bit ASCII binary equivalent, making it easy to see the binary encoding of any text. All conversions happen locally in your browser — no data is sent to any server.
How to Use
- To convert text to binary, type or paste your text into the input area and click Text → Binary.
- To convert binary to text, paste space-separated or continuous 8-bit binary strings and click Binary → Text.
- The output shows character count and binary length for reference.
- Click Copy to copy the output to your clipboard.
Frequently Asked Questions
What is binary representation?
Binary is a base-2 number system using only the digits 0 and 1. Computers store all data as binary. In text-to-binary conversion, each character is represented by its ASCII code expressed as an 8-bit binary number.
What format does the binary output use?
Each character is converted to an 8-bit binary string (padded with leading zeros if needed). The binary values for each character are separated by spaces for readability. For example, “Hi” becomes “01001000 01101001”.
Can I paste binary without spaces?
Yes. The converter accepts both space-separated binary strings and continuous binary strings without spaces. For continuous strings, the total length must be a multiple of 8 so it can be split into valid 8-bit chunks.
Does this support Unicode characters?
This tool converts characters using their JavaScript character code (charCodeAt), which gives the UTF-16 code unit. For standard ASCII characters (letters, numbers, symbols), this produces the expected 8-bit binary representation.
