Superscript & Subscript Generator

Subscript generator for formulas, indices and plain text

For a formula such as H2O, copy the Subscript result to get H₂O where Unicode provides the needed characters. Digits 0–9 and common operators have reliable subscript mappings; lowercase-letter coverage is partial and uppercase subscript letters are not available, so unsupported letters remain unchanged.

Unicode superscript is not font formatting

A word processor can raise ordinary text with formatting. Plain-text fields cannot carry that formatting, so this generator substitutes characters that Unicode already defines in raised or lowered forms. The copied result is text, not an image, CSS rule or downloadable font.

Why some letters stay normal size

Superscript and especially subscript coverage is uneven because the available characters were created for specific notation and phonetic needs, not as complete decorative alphabets. This tool leaves an unsupported character unchanged and lists it beneath the result. That makes gaps visible instead of silently replacing them with misleading look-alikes.

Useful plain-text examples

Digits are useful for exponents and reference markers such as x² or note¹. Subscript digits can represent compact formulas such as H₂O where plain Unicode is appropriate. These characters are convenient text substitutes, but they are not a replacement for semantic math markup, chemical typesetting or accessible document formatting when those formats are available.

Compatibility and accessibility

Rendering, search, pronunciation and field acceptance can vary by app, font and assistive technology. Keep important instructions, names and equations in an accessible source format when meaning matters, and test copied Unicode in the final destination.
