Convert text to real Unicode superscript (ˣ²) or subscript (H₂O), or mixed — no HTML tags. Digit coverage is full; letter coverage follows Unicode.
Details
This tool converts text to superscript (ˣ²), subscript (H₂O), or a mixed form, using real Unicode glyph code points rather than HTML <sup>/<sub> tags — so the result is plain text that works anywhere (chat, social posts, filenames, code comments) without any formatting support.
How it works:
x → ˣ, 2 → ²).2 → ₂, o → ₒ).Unicode coverage caveat (important):
Unicode does not assign a superscript or subscript glyph to every letter. The well-covered sets are:
Characters without a dedicated glyph fall back to themselves — so H₂O works perfectly (H has no subscript glyph, stays as H), but a fully-subscripted sentence will keep its unmapped letters plain. This is a fundamental Unicode limitation, not a bug.
Common uses: chemistry (H₂SO₄, CO₂), math/physics (x², E=mc²), footnote/reference markers (¹²³), trademark-like styling.
Execution
Fill in the form, run the tool, and review the result in one place.

Tool usage guide
The Superscript & Subscript Converter transforms standard text into real Unicode superscript (ˣ²) or subscript (H₂O) characters. Because it generates plain Unicode text rather than HTML tags, the output can be copied and pasted directly into social media posts, chat applications, code comments, and filenames where rich text formatting is not supported.
Background
A teacher wants to post a chemistry quiz question about water on a plain-text school forum.
Problem
The forum does not support HTML formatting, so typing 'H2O' looks unprofessional.
How to use
Input 'H2O' into the text area and select the 'Subscript' style option.
Style: subscriptOutcome
The text is converted to 'H₂O', which displays correctly as a subscript on the forum.
Background
An engineer needs to document a quadratic formula in a code comment.
Problem
Code comments must be plain text, making exponents like 'x2+1' hard to read.
How to use
Input 'x2+1' into the text area and select the 'Superscript' style option.
Style: superscriptOutcome
Unicode does not define superscript or subscript glyphs for all letters. Unsupported characters fall back to their standard form.
Yes, the output is plain Unicode text and works on platforms like X (Twitter), LinkedIn, and Facebook.
No, it uses native Unicode code points, meaning the formatting persists without HTML support.
Yes, all digits from 0 to 9 have full Unicode superscript and subscript representations.
It alternates characters between superscript and subscript positions, which is useful for demonstrating mixed notations.

The text is converted to 'ˣ²⁺¹', clearly indicating the exponent in the source code.
