Strict ASCII covers codes 0 to 127. Between 128 and 159 there are control characters that are not displayed; codes 160 to 255 match ISO 8859-1 (Latin-1), and other code pages such as Windows-1252 assign different symbols to the 128-159 range.

Everything is processed in your browser. What you type is not sent to any server or stored.

How it works and what it does with your text

It's a small, straightforward utility: you paste, choose options and copy the result.

It runs in your browser

The text is transformed by this page's code, on your device. No sign-up or installation needed.

We don't store what you type

We don't send your text to any server or store it. You can check this in the Network tab of your browser's developer tools.

Free and unlimited

Use it as often as you like. It works the same on mobile and on desktop.

Tips to get the most out of it

ASCII, Latin-1 and Unicode

ASCII is 128 characters (7 bits). Latin-1 adds 128 more, with accented vowels and the ñ. Unicode includes more than 150,000 characters from all languages, and its first 256 match Latin-1.

HTML entities

The entities é or é display an é even if the page doesn't declare its encoding properly. Use “Convert only non-ASCII characters” to escape just what is needed.

Escapes in JavaScript and CSS

\u00E9 works in JavaScript and JSON strings; \E9 in the CSS content property. Emojis outside the basic plane are written as \u{1F600} in JavaScript.

Control codes

The first 32 codes are not printed: 9 is tab, 10 is line feed (LF), 13 is carriage return (CR) and 27 is escape. In the table you will see them by their abbreviation.

Frequently asked questions

What is ASCII code?

It is a table that assigns a number to each basic character: “A” is 65, “a” is 97 and “0” is 48. It was created so computers could exchange text.

How many characters does the ASCII table have?

128 in the original ASCII (0 to 127). The so-called extended ASCII table of 256 characters is not a single standard: there are several, such as Latin-1 or Windows-1252.

What is the ASCII code for ñ or accented vowels?

They are not in the original ASCII. In Unicode and Latin-1, ñ is 241 (F1) and Ñ is 209 (D1); á is 225 (E1) and é is 233 (E9).

How do I convert a text to ASCII?

Type the text, choose “Decimal” or “Hexadecimal” and you will see the code of each character. To go back to text, choose “Codes → text” and paste the numbers.

Do you have a repetitive task with texts or data?

We turn it into a custom tool or automation for your business. Tell us what you do by hand and we'll assess it with no commitment.
