ASCII Converter

What Is the ASCII Converter?

The ASCII Converter is a free, browser-based tool that converts text into ASCII character codes. Type or paste text, click Process, and it returns one line per character in the form “Character = Code”, for example “H = 72”. ASCII (American Standard Code for Information Interchange) assigns a number from 0 to 127 to each letter, digit, punctuation mark, and control character.

Everything runs in your browser. You do not need to install software, create an account, or upload anything.

How to Use the ASCII Converter

1. Open this page and type or paste your text into the workspace box.
2. Click Process.
3. Read the result: one “Character = Code” entry for each character in your input, in order.
4. Use Copy to copy the result, Download to save it, or Clear to start over with different text.

Worked Example

In an observed test, the input was “Hi!”. The tool returned: “H = 72 i = 105 ! = 33”. That matches the standard ASCII table: capital H is 72, lowercase i is 105, and the exclamation mark is 33. Spaces and punctuation are also converted — a space is 32 — so every character in the input gets its own entry.

Limitations

• One-way only in the observed workspace: The workspace converts text to codes. It offers no mode to convert codes back into text, so to decode a list of numbers you must look them up manually or use another tool.
• ASCII range only: The standard ASCII table covers 0 to 127. Characters outside that range, such as accented letters, emoji, or non-Latin scripts, do not have standard ASCII codes, and the tool’s behavior for them should not be treated as a Unicode or UTF-8 conversion.
• No binary, hex, or octal output: The tool shows decimal codes only. It does not show the binary, hexadecimal, or octal form of each code.
• No separator options: The output format is fixed as “Character = Code” entries. There is no option to output comma-separated codes, space-separated codes, or codes without the characters.
• Control characters: Codes below 32 are non-printable control characters. Their entries may be hard to read because there is no visible character to show.

Frequently Asked Questions

What is ASCII?

ASCII is a character-encoding standard that assigns a number from 0 to 127 to each basic Latin letter, digit, punctuation mark, and control character, so computers can store and exchange text as numbers.

What is the ASCII code for the letter A?

Capital A is 65, and lowercase a is 97. In the observed test, capital H was 72 and lowercase i was 105, showing that upper- and lowercase letters have different codes.

Can I convert ASCII codes back to text with this tool?

No. The observed workspace converts text to codes only, with no reverse mode. To decode, look up each code in an ASCII table.

Does this tool handle emoji or accented letters?

Not as ASCII. Emoji and accented letters are outside the 0 to 127 ASCII range, so do not treat any output for them as a standard ASCII code.

Summary

The ASCII Converter is a quick, private way to see the decimal ASCII code for each character in a short piece of text. It is best for learning, debugging, and checking single characters; it is not a general Unicode converter or a decoder.
