Superscript Generator
Convert text to Unicode superscript or subscript characters online for free. Supports letters, numbers, and common symbols with instant copyable output and character-by-character breakdown.
About This Calculator
The Superscript Generator converts any text into Unicode superscript or subscript characters that stay formatted no matter where you paste them. Whether you need to write mathematical exponents like x², chemical formulas like H₂O, or create aesthetic social media posts, this free online tool transforms your text instantly.
Unlike formatting in a word processor (which only visually transforms characters and loses the effect when pasted into plain text), this generator uses real Unicode characters that preserve their superscript or subscript appearance in any Unicode-compatible environment — including web pages, emails, messaging apps, and documents. The tool maps each character to its Unicode equivalent using the dedicated superscript (U+00B9, U+2070-U+207F, U+1D2C-U+1DBB) and subscript (U+2080-U+209C) code blocks. Characters without a dedicated Unicode code point are left in their original form and marked as unavailable in the breakdown table.
Superscript Unicode coverage includes all digits (0-9), most letters (excluding q and Q), and common math symbols. Subscript coverage includes all digits but a more limited set of letters. The breakdown table shows every character with its conversion status, making it easy to see which characters were transformed and which remained unchanged.
Regional Notes
Global: Unicode superscript and subscript characters are supported on virtually all modern devices and platforms including Windows, macOS, iOS, Android, and Linux. The converted text works in web browsers, email clients, messaging apps, and social media platforms that support Unicode.
Frequently Asked Questions
How does the Superscript Generator work?
Type or paste your text into the input box, choose Superscript or Subscript mode, and click Convert. Each character is mapped to its Unicode superscript or subscript equivalent. Characters without a Unicode equivalent remain in their original form.
What characters can be converted to superscript?
All ten digits (0-9) and most lowercase and uppercase letters (except q and Q) have superscript Unicode characters. Common math symbols like +, -, =, (, ) also have superscript versions. Characters without a supercript equivalent are left unchanged.
What is the difference between superscript and subscript?
Superscript characters appear above the normal text baseline (e.g., x²), while subscript characters appear below the baseline (e.g., H₂O). Superscript has broader Unicode coverage with most letters available, while subscript only covers a subset of letters (a, e, h, i, k, l, m, n, o, p, r, s, t, u, v, x) plus all digits.
Is this Superscript Generator free to use?
Yes, it is completely free to use with no registration or hidden charges. You can convert unlimited text to superscript or subscript.
Why are some characters not available in superscript?
The Unicode Consortium only created superscript characters for symbols commonly used in scientific and mathematical writing. Letters and symbols that are rarely needed as superscripts were not given their own Unicode code points. The converter leaves these characters in their original form.
How do I use superscript in Word or Google Docs?
In Microsoft Word, use the x² button in the Home tab or press Ctrl+Shift++ (Windows) or Cmd+Shift++ (Mac). In Google Docs, select your text and press Ctrl+. (Windows) or Cmd+. (Mac). This converter is useful when you need superscript characters that stay formatted even in plain-text environments.
Can I share my superscript conversion results?
Yes, the URL automatically saves your input text and mode. You can bookmark or share the link to revisit the exact conversion.
Where are superscript and subscript used?
Superscript is used for exponents in math (x²), ordinal indicators (1st, 2nd), chemical ion charges (Ca²⁺), and academic citation footnotes. Subscript is used for chemical formulas (H₂O, CO₂), mathematical sequences, and scientific notation.
