Key features

  • Convert text to ASCII decimal, hex, binary, or octal
  • Convert character codes back to text
  • Handles full Unicode (not just ASCII range)
  • Space-separated or comma-separated output options
  • Shows the ASCII table for reference

How to use ASCII / Character Code Converter

  1. 1Enter your text in the input box to see ASCII codes
  2. 2Or enter space-separated decimal/hex codes to decode to text
  3. 3Select the output format: decimal, hexadecimal, binary, or octal

Frequently asked questions

What is the ASCII code for a space character?
A space character has ASCII code 32 (decimal), 20 (hex), or 00100000 (binary).
Can this converter handle Unicode characters beyond ASCII?
Yes. The tool handles all Unicode characters. Non-ASCII characters will show their Unicode code point values, not just 0-127.
What is the difference between ASCII and Unicode?
ASCII is a 7-bit character set covering 128 characters (English letters, digits, common symbols). Unicode is a superset that covers over 140,000 characters from all world scripts.
Why do I get different decimal values for the same character on different systems?
If a character is outside the standard ASCII range (0–127), its encoding depends on the character set being used (UTF-8, Windows-1252, etc.). The tool uses Unicode code points.
