ASCII Converter
Type text to get the ASCII decimal code of each character, or paste codes to rebuild the text. A live reference lists every character with its decimal and hex value. It runs in your browser.
This ASCII converter turns text into ASCII codes and turns codes back into text, so a char to ASCII lookup and its reverse sit on one page. Type a word and you get the decimal code point of each character; paste a list like 72 105 and it reads back as “Hi”. The panel underneath is a live ascii code lookup that lists every character you entered next to its decimal and hex value, which helps when you are hunting for one specific control code. Plain ASCII stays in the 0–127 range, and characters beyond it show their Unicode code point.
How it works
- 1
Choose a direction
Pick Text → ASCII to read the codes, or ASCII → Text to turn a list of numbers back into characters.
- 2
Read or copy
The output updates as you type. Set the separator to spaces, commas or new lines when encoding, then copy it.
- 3
Use the lookup
The character table below shows each character with its decimal and hex code, so you can check one value at a glance.
Instant & 100% private — nothing is uploaded
Everything runs locally in your browser. Your code, text and files are processed on your own device and are never sent to a server — so there are no upload waits, no size limits from us, and nothing is ever stored or logged.
Frequently asked questions
- What is an ASCII code?
- It is the number assigned to a character. Capital A is 65, a space is 32, and so on. This tool shows the decimal code for each character you type.
- How do I convert text to ASCII codes?
- Type in Text → ASCII mode. Each character is turned into its decimal code, joined by the separator you pick, and you can copy the whole list.
- What happens with characters beyond ASCII?
- True ASCII covers 0 to 127. For characters past that, like é or €, the converter shows the Unicode code point instead, and decoding rebuilds them correctly.
- What is the character lookup table for?
- It is a live ascii code lookup of exactly what you entered, showing each character next to its decimal and hex value, which is quicker than scanning a full chart.
- Is any of this uploaded?
- No. The char to ASCII conversion and the lookup both run in your browser.
