About ASCII / Unicode Converter
Every character has a numeric code: ASCII (0–127) or Unicode code point. This tool converts a character to its decimal and hex values, or a code (decimal, hex, or U+xxxx) to the corresponding character. Handy for escape sequences, debugging encoding, and documentation.
How to use
- Character → Code: Type or paste a character; the result updates and shows decimal, hex, and Unicode.
- Code → Character: Enter a number (e.g. 65), hex (0x41 or U+0041), then click Convert.
Frequently Asked Questions
What is the difference between ASCII and Unicode?
ASCII covers 0–127 (7-bit). Unicode assigns a code point to almost every character; this tool shows both decimal and hex (U+xxxx) for any character.
Is my input sent to a server?
No. Conversion runs entirely in your browser.
Can I convert multiple characters?
Yes. Enter a string; the tool shows the first character in detail. For full string you can use Character & Byte Count or process one char at a time.
