Superscript & Subscript Text Generator (Unicode, copy-paste)

Real-world use cases

• Write math notation where there is no equation editor

  You are typing a homework answer in a forum reply, a Discord study group or a plain-text email, and you need x² + y² = r² or n³. Type x2 + y2 = r2 and n3, copy the superscript output, and the exponents paste in as real characters that survive the send. No screenshots of an equation editor, no LaTeX the reader cannot render — just text that reads correctly everywhere.

• Format chemical formulas for a report or slide

  A chemistry write-up needs H₂O, CO₂, C₆H₁₂O₆ and SO₄. Switch to subscript, type H2O, CO2, C6H12O6 and SO4, and copy each one into your document, spreadsheet or presentation. Because the letters stay full size and only the numbers drop, the formula matches textbook convention without any special font or chemistry plugin.

• Add a clean unit or footnote mark to a spreadsheet

  Spreadsheet cells take plain text only, so an area column labeled m² or a volume labeled m³ normally means hunting through a symbol menu. Type m2 or m3 in superscript mode, copy the single character, and paste it into the header. The same trick gives you footnote marks like ¹ and ² next to a value without breaking the cell formatting.

• Style a social bio or username with tiny characters

  Instagram, TikTok and X bios only accept plain text, but superscript and subscript letters read as a smaller, raised or lowered accent — a subtle look that stands out in a feed. Type a word, pick a direction, and copy the small-character version into your bio, knowing the unsupported-character notice warns you before any letter would have shown up as a box.

Common pitfalls

• Expecting every letter to convert. Unicode only assigns small forms to some characters — there is no superscript q and no subscript b, c or d. The tool leaves those at normal size and lists them under the output, so check that notice before assuming a word came out fully styled.

• Confusing this with HTML sup and sub. Those tags only work inside rendered HTML and disappear in plain text. If your destination is a spreadsheet, a filename or a chat box, use this Unicode output instead so the small characters actually stick.

• Picking the wrong direction for a chemical formula. Exponents like x² go in superscript mode, but a formula like H₂O needs subscript mode. Running H2O through superscript gives H²O, which is wrong — the digit in a formula sits low, not high.
