Text Output
Binary is the fundamental language of computers. This tool converts 8-bit binary groups (bytes) back into human-readable ASCII or UTF-8 text, useful for computer science education and debugging encoded data.
Each character is represented by an 8-bit binary number. For example, "A" is 01000001 (decimal 65 in the ASCII table). Understanding this is foundational to computer science.
Use the swap button to instantly switch modes — convert text to binary too. The tool handles both directions making it a complete binary/text workbench.
All conversion happens locally in JavaScript. No data leaves your browser — safe for sensitive string analysis and educational environments.
