What Are Superscript and Subscript Characters?

Superscript characters appear slightly above the normal text line, while subscript characters appear below it. They are commonly used in mathematics, chemistry, scientific notation, and formatted text.

Examples include:

Superscript: x², 10³
Subscript: H₂O, CO₂

Unicode includes special characters that allow supported text to appear in these formats without requiring complex formatting or HTML.

What Characters Can Be Converted?

Unicode provides superscript and subscript forms for many numbers, selected letters, and mathematical symbols. However, not every standard character has a dedicated superscript or subscript equivalent. The result therefore depends on which characters the tool supports.
