How to use Text to ASCII Converter

1
Choose a direction
Use the toggle to pick Text to ASCII or ASCII to Text. The swap button moves your result into the input so you can convert it back the other way.
2
Enter your data
Type or paste text, or paste a list of decimal codes such as 72 105. The conversion runs automatically as you type.
3
Pick a separator
When encoding, choose whether the codes are separated by spaces or commas. Decoding accepts spaces, commas, and new lines in any mix.

4
Copy the result
Review the converted output and copy it to your clipboard, ready to paste wherever you need it.

Frequently asked questions

What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding that assigns a number to each letter, digit, and common symbol. For example, capital A is 65, lower-case a is 97, and the space character is 32. Storing text as these numbers is how computers have represented letters since the 1960s.

How does this converter handle emoji and accented letters?

Standard ASCII only defines codes 0 to 127, but this tool extends to the full Unicode range, so accented letters, emoji, and other symbols convert to their Unicode code points. For example, é becomes 233 and 😀 becomes 128512. Decoding accepts any code from 0 up to 1114111.

How should I format codes for decoding?

Enter each character code as a plain decimal number and separate them with spaces, commas, or new lines — you can mix separators freely. Leading zeros are fine, so 072 and 72 both decode to the letter H.

What is the difference between ASCII, binary, and hexadecimal?

They are three ways of writing the same character codes. ASCII shows the code in decimal (H is 72), binary shows it in base 2 as 01001000, and hexadecimal shows it in base 16 as 48. Use whichever your task calls for; the underlying numbers are identical.

Is my data uploaded to a server?

No. All conversion happens entirely in your browser. Your text is never uploaded, logged, or stored, so it stays completely private and the tool keeps working even when you are offline.
