Superscript and Subscript Generator

Turn text into Unicode superscript and subscript characters for footnotes, math, and chemistry.

Both versions update live as you type. Nothing leaves your browser.

Characters with no small form

Letters with no superscript or subscript form are left unchanged.

How to make superscript and subscript text online

  1. Type or paste your text

    Enter the letters, digits, or symbols you want to raise or lower, such as an exponent, a footnote number, or a chemical formula.

  2. Read both previews

    The superscript and subscript versions update live as you type, each shown in its own card.

  3. Check the unsupported note

    Any character with no superscript or subscript form is listed under the result and left unchanged, so you can adjust your text if needed.

  4. Copy the version you need

    Click the copy button on the superscript or subscript card and paste the small characters wherever you like.

Why use this tool

Superscript and subscript at once

Type text once and get both the raised superscript and the lowered subscript version side by side, each with its own copy button.

Built for footnotes, math, and chemistry

Digits and the plus, minus, equals, and parenthesis signs all convert, so exponents like x2, footnote markers, and formulas like CO2 come out right.

Keeps characters it cannot convert

Letters with no super or subscript form, like a capital H or the letter q, are left in place by default so a formula like H2O still reads correctly.

Every unsupported character is listed

Below each result the tool names any characters that have no superscript or subscript form, so you know exactly what did and did not change.

Real Unicode, not a font

The output is ordinary Unicode text, so it survives copy and paste into bios, chat, spreadsheets, and plain-text documents without any special font.

About this tool

This generator maps the characters you type onto Unicode superscript and subscript code points, the same small raised and lowered characters used in footnotes, exponents, and chemical formulas. Because the result is real Unicode text rather than a font or an image, you can paste it into places that strip formatting, like social bios, chat, spreadsheets, and plain-text documents, and the small characters travel with it.

Digits 0 to 9 and the signs plus, minus, equals, and parentheses have both superscript and subscript forms, so math like x2 or an ionic charge converts cleanly. Letter coverage is uneven: most lowercase letters have a superscript form, but Unicode never defined a superscript q, and several capitals such as C, F, Q, S, X, Y, and Z have no raised form at all. Subscript letters are rarer still, covering only a handful like a, e, h, i, and x. Characters with no matching form are listed under each result and left in place by default, which is why a formula like H2O keeps its H and O while the 2 drops to a subscript.

Type once and copy either the superscript or the subscript version. To restyle whole words in bold, italic, or script instead, use the fancy text generator, and to see exactly which code points a converted string uses, paste it into the Unicode inspector. Everything runs on your device.

Frequently asked questions

How does the superscript and subscript generator work?
It maps each character you type onto a matching Unicode superscript or subscript code point. These are real Unicode characters, not images or a special font, so the small text is just text you can copy and paste almost anywhere.
Why did some letters not convert?
Unicode only defines superscript and subscript forms for some characters. There is no superscript q, several capital letters have no raised form, and subscript letters cover only a small set. Any character with no matching form is listed under the result and left unchanged.
Can I make chemical formulas like H2O or CO2?
Yes. Digits convert to subscripts while letters that have no subscript form stay in place, so typing H2O gives H2O with a subscript 2 and CO2 gives CO2 the same way. Type the formula and copy the subscript version.
Will the small characters work everywhere I paste them?
They are standard Unicode, so they render in most modern apps, browsers, bios, and documents. A few older systems or limited fonts may not display every glyph, so preview important text where you plan to use it.
Is my text uploaded anywhere?
No. Everything runs in your browser; nothing is sent to a server, stored, or logged.
