What this tool does
Choose Encode or Decode, paste a value, and copy the result that updates immediately.
Encoding standard
The converter follows the original 7-bit ASCII range from decimal 0 through 127, including printable characters and control codes.
How data is represented
Text-to-ASCII produces space-separated decimal values. ASCII-to-text accepts decimal values separated by spaces, line breaks or commas.
Example
ABC becomes 65 66 67, and entering 72 101 108 108 111 produces Hello. Control codes may create invisible output.
Input validation
Every decoded token must be a decimal integer between 0 and 127. Encoding rejects accented letters, emoji and other non-ASCII characters.
Limitations
ASCII is not Unicode and cannot represent most writing systems. Use the binary text converter when UTF-8 support is required.
Privacy
All byte conversion runs locally in your browser; input and output are never uploaded by this tool.
