Subscript Generator - Copy & Paste Tiny Text

Generate Unicode subscript text instantly. Subscript characters are tiny letters and digits that sit below the normal baseline - perfect for chemistry formulas (H₂O), math (xₙ), footnote references, and decorative usernames in apps that accept Unicode.

What subscript actually is

Subscript is a typographic style - characters shifted below the line - but in plain text we don't have formatting. Unicode solved this by assigning specific codepoints for subscript variants of common digits, math symbols, and a handful of letters. When you copy our output, you're copying real Unicode characters that travel with your text everywhere it goes, no formatting required.

What can be subscripted

• All digits 0-9 (₀-₉) - assigned at Unicode block U+2080–U+2089
• Math operators + − = ( )
• Lowercase letters: a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, x - scattered across Unicode blocks (Spacing Modifier Letters, Phonetic Extensions, Latin Extensions)

Unicode does not have subscript forms for b, c, d, f, g, q, w, y, z (lowercase) or any uppercase letters. Those characters pass through unchanged.

Common use cases

• Chemistry formulas: H₂O, CO₂, C₆H₁₂O₆
• Math notation: xₙ, aᵢ, log₂
• Footnote references in plain-text documents
• Decorative usernames in Instagram, Twitter, Discord, gaming platforms
• TikTok and Reddit captions
• Marking variables in scientific writing

Sources & references

Unicode subscript characters are defined across blocks U+2080–U+209F (Subscripts and Superscripts), U+2090–U+209C (subscript letters), and several supplementary phonetic blocks. See the official Unicode standard at unicode.org/charts.
