Convert any text to Unicode superscript (ˢᵘᵖᵉʳ) or subscript (ₛᵤᵦ) characters — copy and paste anywhere without special formatting. Includes small caps, ordinal shortcuts (1ˢᵗ 2ⁿᵈ), fraction symbols, and a live character map.
Enter the text you want to convert. As you type, the superscript and subscript outputs update in real time. You can type chemical formulas (H2O → H₂O) or mathematical exponents (x2 → x²).
Select Superscript to raise characters above the baseline, Subscript to lower them below, or Small Caps for stylised text in documents. Use the preset buttons for common formulas, ordinals and fractions.
The output uses standard Unicode characters — no special software or formatting needed. Copy and paste into social media bios, emails, documents, chat apps, or anywhere that accepts text.
Unicode contains dedicated code points for characters that visually appear raised (superscript) or lowered (subscript) — for example the superscript digits ⁰¹²³⁴⁵⁶⁷⁸⁹. Because these are standard Unicode characters, they can be copied and pasted into any application that supports Unicode — which includes virtually every modern app, website, and messaging platform.
Not all letters have official Unicode equivalents. Superscript has most lowercase letters and all digits. Subscript has all digits but only a limited set of letters (mainly those used in chemical and mathematical notation). Where official equivalents do not exist, this tool uses the closest-looking Unicode characters as visual substitutes.
Ordinal suffixes are the raised letters after a number: 1ˢᵗ, 2ⁿᵈ, 3ʳᵈ, 4ᵗʰ. This tool includes a one-click ordinal generator. Common ordinals (1st through 21st) are available as presets for quick insertion.
HTML superscript uses the sup tag and only works in HTML. Unicode superscript uses actual Unicode characters. This works everywhere Unicode is supported — plain text files, SMS, social media, chat apps, and email — without any special rendering engine. For web pages you control, the HTML sup tag is preferred for accessibility.
Yes — Unicode superscript and subscript characters work on Instagram, Twitter/X, Facebook, LinkedIn, WhatsApp, Discord, Telegram, and most other platforms. Some older platforms may filter out non-standard Unicode. Always test on your target platform before using in important posts.
Small caps displays lowercase letters as smaller versions of uppercase letters. Unicode small caps uses dedicated code points (ᴀ ʙ ᴄ ᴅ etc.) that render consistently without CSS or font styling. Small caps are used in book typography, academic papers, headings in formal documents, and for stylistic effect in social media bios.
