How do I type superscript or subscript text?

Enter letters or numbers, choose the Superscript, Subscript, Mixed, or Numbers filter, and copy the result you need.

Can I make H2O with a subscript 2?

Yes. Enter H2O and select a number-only subscript result to create H₂O while keeping H and O ordinary.

Can I make x squared?

Enter x2 and choose a number-only superscript result to create x².

Why did some letters stay normal size?

Unicode does not provide a matching superscript or subscript form for every letter. Unsupported characters remain readable instead of being replaced inaccurately.

Are superscript and subscript characters real formatting?

They are separate Unicode characters, not CSS font sizing or editor formatting. Their exact appearance depends on the destination font.

Should I use this for formal equations?

Use a semantic equation editor, MathML, or LaTeX for formal mathematics. This tool is best for short copy-and-paste text fields.

Letter Symbols

Convert Text to Superscript or Subscript

Superscript characters sit visually above the baseline and are often used for exponents, footnote-like labels, ordinal endings, and compact decorations. Subscript characters sit below the baseline and are useful in short formulas and scientific notation. The output remains Unicode text that can be copied into supported fields.

Use Number-Only Modes for Formulas

When you enter H2O, CO2, x2, or a short equation, number-only options change the digits while preserving the ordinary letters. This is often more accurate than shrinking the whole phrase. The tool also supports superscript and subscript plus, minus, equals signs, and parentheses where Unicode provides them.

Unicode Does Not Contain Every Tiny Letter

There is no complete, perfectly matching superscript or subscript alphabet for every Latin capital and lowercase letter. The generator uses recognized modifier and subscript characters where available and leaves unsupported characters unchanged. It does not substitute unrelated symbols merely to make every letter look small.

Text Utility, Not Mathematical Typesetting

These characters are convenient for bios, messages, labels, and simple formulas, but they do not replace semantic equation editors, MathML, LaTeX, or accessible document formatting. Use proper scientific typesetting when structure and screen-reader interpretation matter.

Copy, Test, and Keep a Plain Version

Some apps display modifier letters at different sizes or reject them in usernames. Copy the result, paste it into the exact destination, and retain a plain-text version for search, accessibility, and compatibility. Progressive loading keeps the long option list light on mobile.

How to Use Superscript and Subscript Tool

Use the focused superscript and subscript tool directly below the page heading. The first useful results appear immediately, and the remaining options reveal progressively as you scroll.

Enter or paste text in the tool, or search by character or keyword in the symbol finder.
Use the focused filters to narrow the available conversions, styles, or symbol categories.
Review the visible results and scroll to reveal the next lightweight batch automatically.
Press Copy on the exact result you want, then test it in the destination app or document.
