Subscript generator

Convert supported numbers, operators and letters into real Unicode subscript characters ready to copy and paste.

Normal textSubscript output

Unicode does not define a matching raised/lowered form for every character. Unsupported characters are left unchanged.

What this generator converts

Unicode contains digits ₀–₉, several operators and a limited set of subscript letters. SymbolDex only converts characters with a real encoded counterpart and leaves the rest unchanged.

Common uses

Unicode subscripts are convenient for short formulas such as H₂O, labels and plain-text notation. For complex equations, use a math editor or the document format’s native subscript support.
