Subscript Generator
Convert supported letters and numbers to Unicode subscripts, or lower only the digits in a formula.
ₕ₂ₒ
All digits 0–9 are supported. Letters b, c, d, f, g, q, w, y and z have no mapping in this tool and stay unchanged. Supported uppercase letters use the same lowercase subscript forms. This does not parse or validate formulas.

What is Subscript Font?
This subscript generator converts supported English letters and all ten digits into small Unicode characters below the baseline. Choose all supported characters for small text, or numbers only for formulas such as H₂O and CO₂. Unicode has no complete subscript alphabet, so unsupported letters stay unchanged.
Low, compact, and slightly scientific. Subscript adds quirky texture without replacing the whole alphabet with a heavy decorative style.
Best for copying subscript numbers in simple formulas, small labels, and short text that can accommodate a partial alphabet.
