Free online ASCII converter. Convert text to ASCII / Unicode character codes and convert codes back to text instantly. Runs 100% in your browser with no uploads.
What are ASCII and Unicode character codes?
Every character has a number. ASCII, from 1963, assigned 0-127 to English letters, digits and control characters — 'A' is 65, 'a' is 97, space is 32. Unicode extended the same first 128 codes to cover every writing system and emoji, currently defining nearly 300,000 code points.
This converter shows the full Unicode code point for any character and converts space-separated codes back to text — handy for debugging encoding issues and understanding what programs actually store.
