About ASCII Lookup
Use this free ASCII / Unicode Character Lookup to quickly get accurate results in seconds, free and instantly offline with no signup required ever, trusted by professionals in Austin, Chicago, Miami, Denver, Seattle, and New York for reliable daily use without accounts, subscriptions, limits, or delays on any device for everyday personal and business workflows daily.
ASCII / Unicode Character Lookup: Every character you type has a unique numeric code point. This free tool instantly shows you the decimal, hexadecimal, binary, and octal values plus both decimal and hex HTML entities for any character you enter — all offline with no signup required ever.
ASCII Range: Standard ASCII covers code points 0-127, including letters, digits, punctuation, and control characters. Extended ASCII goes from 128-255. Unicode extends far beyond into thousands of scripts, emoji, and mathematical symbols. The tool handles the full range from basic ASCII to complex Unicode characters.
Code Point Formats: The tool displays the code point in multiple formats simultaneously: decimal (like 65 for A), hexadecimal (U+0041), binary (01000001), and octal (101). It also generates both HTML entity formats — decimal (A) and hex (A) — ready to paste into your markup.
Control Characters: Special names are provided for common control characters like TAB (9), LINE FEED (10), CARRIAGE RETURN (13), and ESCAPE (27). These invisible characters are frequently the source of encoding bugs in data processing pipelines.
HTML Entity Usage: HTML entities let you display special characters without typing them directly. This is essential for reserved characters like < (less-than), > (greater-than), and & (ampersand) that have special meaning in HTML. The tool gives you both forms prepared for immediate use.
Privacy and Speed: All lookups happen instantly in your browser. No data is transmitted anywhere, and the tool is completely free with no signup required ever. Works offline once loaded.

Frequently Asked Questions
- What is a code point?
- A code point is the unique numeric value assigned to a character by Unicode. For example, uppercase A is U+0041 (65 in decimal). Emojis and complex scripts have much larger code points.
- How do I use HTML entities?
- Write A (decimal) or A (hex) inside HTML to display a character without typing it directly. The tool gives you both forms prepared for immediate use.
- Is this tool free to use?
- Yes, this ASCII / Unicode lookup is completely free. Look up any character instantly offline with no signup required ever.
- Does it handle emojis?
- Yes. The tool supports the full Unicode range including emoji, mathematical symbols, and characters from all world scripts. Emojis typically have code points above 128000.
- What are control characters?
- Control characters are invisible characters that format text, like TAB (9), LINE FEED (10), and CARRIAGE RETURN (13). The tool identifies these by name.
- Can I look up multi-character strings?
- The tool processes one character at a time. For multi-character strings, look up each character individually to build your HTML entity sequences.
