Subscript Text Generator
Drop your text below the baseline using Unicode subscript characters — commonly used for chemical formulas like H₂O and mathematical notation.
Subscript
gₗyₚₕdᵣᵢₚ
Examples
- H₂O
- xₙ₊₁
- CO₂
How it works
Unicode only defines subscript glyphs for a limited set of characters — digits, a handful of lowercase letters, and a few math operators — because the block was designed for scientific notation, not general text. No uppercase subscript letters exist at all, so uppercase input is left unchanged.
Where you can use it
- Chemical formulas in captions or notes
- Math notation pasted into plain-text fields
- Stylized usernames using the limited character set

Frequently asked questions
Why do only some letters convert?
Unicode simply never defined subscript glyphs for every letter — coverage is intentionally limited to what's needed for scientific notation. Unsupported letters are left exactly as typed.
