About this tool

Superscript Generator converts ordinary text into Unicode superscript or subscript characters that you can copy and paste anywhere that accepts plain Unicode text. Pick superscript for raised small text like exponents (x squared, 10 to the 3rd), ordinals (1st, 2nd, 3rd), footnote markers, and trademark notes, or pick subscript for lowered small text like chemical formulas (H2O, CO2, C6H12O6) and math indices. Unlike a rich-text editor, the output is made of real characters such as superscript two (U+00B2) and subscript x (U+2093), not HTML tags or styling, so the small text survives copy and paste into fields that strip bold, italic, and formatting: X and Instagram bios, YouTube and TikTok comments, Discord, Reddit, spreadsheets, code comments, and plain-text forms. Type or paste on the left and the converted text appears instantly on the right, with the opposite style shown underneath so you can grab either one. Coverage is a property of the Unicode standard rather than the tool: superscript and subscript digits 0 to 9 and the signs plus, minus, equals, and parentheses all exist and render reliably, superscript letters cover almost the whole lowercase alphabet plus most capitals, and subscript letters exist only for a limited set (a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, x). Any character with no mapping in the chosen mode is left unchanged so words keep their shape, and the tool flags letters it could not convert. A built-in reference chart lists every available superscript and subscript character for the active mode. Iteration runs by Unicode code point, so emoji and accented characters are never split. Everything is computed locally in your browser. Your text is never uploaded, never stored on a server, and disappears when you close the tab. For body text on a web page, prefer real HTML superscript and subscript tags, since screen readers and search engines may treat these characters differently from normal letters.
