How to use Text to ASCII Codes

Type your text, and the tool converts every character to its ASCII code number — paste codes in decode mode to convert them back to text.

Frequently asked questions

What is ASCII?

ASCII (American Standard Code for Information Interchange) assigns numbers 0-127 to characters. For example, 'A' is 65, 'a' is 97, '0' is 48.

What's the difference between ASCII and Unicode?

ASCII uses 7 bits (128 characters). Unicode extends this to millions of characters including emoji and international alphabets.

Can I decode ASCII numbers back?

Yes, enter ASCII codes separated by spaces and decode them back to text. Each number from 0-127 represents a specific character.
