Convert binary to text
3 free tools
Binary is the base-2 number system used at the lowest level of all digital computers. These tools cover the most common binary tasks: converting text to its binary representation, decoding binary strings back to readable characters, and converting binary numbers to decimal and back. All conversions run instantly in the browser with no upload required.
Each character is converted to its ASCII (or Unicode) code point, then that number is written in base-2. For example, 'A' (code 65) becomes 01000001.
Binary is base-2 (uses only 0 and 1). Decimal is base-10. The tool reads each binary digit as a power of 2 and sums them to produce the decimal equivalent.
Yes. All conversions happen entirely in your browser with no server involvement.
