What this tool does
ASCII Converter displays Character, Decimal, Hex, and Binary for each input character. The standard ASCII range is 0 to 127; Unicode characters outside the range are clearly marked with a Code Point and are not mistakenly called ASCII.
- Text-to-code view lists results character by character.
- Decimal code reverse conversion strictly accepts 0 to 127.
- Control characters will use identifiable names or escape descriptions to avoid misunderstandings caused by outputting invisible content.
How to use it

FAQ
What is the standard range of ASCII?
Standard ASCII uses 7 bits and has a decimal range of 0 to 127.
Are Chinese characters ASCII?
No. The page labels it as Unicode and displays its actual code point.
How are control characters displayed?
Invisible control characters are rendered as names or escape descriptions rather than pretending to be blank.
Will the conversion upload text?
No, character traversal and transcoding occur within the browser.
