Type x² or 2⁴ correctly in plain text. This tool converts letters, digits and maths symbols into superscript characters you can paste anywhere.
| Input | Output |
|---|---|
| x2 (Tiny / superscript) | ˣ² |
| 10-3 (Tiny / superscript) | ¹⁰⁻³ |
| Ca2+ (Tiny / superscript) | ᶜᵃ²⁺ |
Ideal for plain-text maths and science: exponents (m², 10⁻³), ionic charges (Ca²⁺), unit notation and footnotes. If you are writing inside Word, Google Docs or a LaTeX document, use that editor's own superscript formatting instead — it stays editable as real formatting.
On Windows you can hold Alt and type 0178 on the numeric keypad for ². On macOS open the Character Viewer from the Edit menu and search for 'superscript'. This tool is faster when you have several characters to convert at once.
No. Formatted text is normal letters with a formatting flag attached, and the flag disappears when the formatting is not supported. These are separate Unicode characters, so the look survives everywhere — but they are also different characters, which means they cannot be searched for as ordinary text and some databases reject them.
For charges and exponents yes: Ca²⁺, K⁺ and 10⁻⁷ all render correctly. Molecular formulas such as H₂O and CO₂ need subscripts instead, so use the subscript generator for the numbers below the baseline.
Because the modifier-letter set is incomplete. Common letters such as a, b, c, e, n, o, r, s, t and x all have forms, while q has none. Digits and operators are complete, so numeric exponents are always exact.
