How Unicode superscript text works
This tool converts standard numbers and mathematical symbols into native Unicode raised characters (such as ² for 2 or ⁻ for -). Because the output is plain Unicode text rather than rich-text formatting, you can copy and paste the result into social media posts, messaging apps, and plain-text editors without losing the superscript appearance.
Common applications
| Category | Example Input | Superscript Output |
|---|---|---|
| Exponents & Algebra | x2, y3, 2^4 | x², y³, 2⁴ |
| Scientific Notation | 10-2, 6.02x10^23 | 10⁻², 6.02×10²³ |
| Ordinals & Dates | 1st, 2nd, 3rd | 1ˢᵗ, 2ⁿᵈ, 3ʳᵈ |
| Footnotes & Citations | Source [1], Item [2] | Source [¹], Item [²] |
Unicode Limitation
While digits 0-9 and basic math signs are universally supported across almost all modern fonts and platforms, rare subscript/superscript letters rely on Unicode's Phonetic Extensions block and may display as empty boxes (□) or missing glyphs on older Android devices or custom app fonts.
Frequently asked questions
Can I use superscript text in emails and social posts?
Yes. The output uses standard Unicode superscript characters, allowing you to paste it into emails, SMS messages, X/Twitter, Instagram captions, and Discord without requiring HTML formatting.
How is this different from HTML <sup> tags?
HTML <sup> tags shrink and raise standard text visually within HTML pages. This generator produces distinct Unicode characters that remain superscript regardless of where they are pasted.
Need lowered text or chemical formulas?
For chemical notation and lowered numbers (like H₂O or x₁), use our Subscript Generator.
