Convert any text to superscript (¹²³) or subscript (₁₂₃) instantly. Perfect for math, chemistry, social media, and academic writing. Free, fast, and 100% client-side.
A fast, free online tool to convert plain text into superscript, subscript, or small caps Unicode characters. Superscript is commonly used for exponents (x²), footnotes (¹), and ordinal numbers (1ˢᵗ). Subscript is used in chemical formulas (H₂O) and mathematical notation. Small caps are great for stylish social media posts. All conversion happens in your browser — no data is sent to any server.
Superscript and subscript text work on most social media platforms (Twitter/X, Instagram, Facebook, TikTok bios), messaging apps (WhatsApp, Telegram), and anywhere that supports Unicode characters. They are also perfect for academic writing, chemistry notation, and math expressions.
This tool supports all characters that have Unicode superscript, subscript, or small caps equivalents. The English alphabet (a-z, A-Z) and digits (0-9) are fully supported. Some special characters and non-Latin scripts may not have direct Unicode equivalents and will be passed through unchanged.
