⁴ Superscript Generator
Convert any text to Unicode superscript (ˢᵘᵖᵉʳ) or subscript (ₛᵤᵇ) characters. Works everywhere Unicode is supported — social media, documents, chats.
⚠ Some characters have no Unicode equivalent and are shown unchanged.
About the Superscript Generator
This tool converts ordinary letters, numbers, and symbols into their Unicode superscript or subscript equivalents. Because the output uses real Unicode characters — not HTML tags or CSS — the resulting text can be pasted into any platform that supports Unicode: Twitter, Instagram, Facebook, Discord, WhatsApp, Google Docs, Notion, and more.
Everything runs entirely in your browser. Your text is never sent to a server, never stored, and 100% private.
Superscript
Superscript characters sit above the normal text baseline. Unicode includes superscript versions of all 26 lowercase letters, most uppercase letters, all 10 digits, and common symbols like + - = ( ). Common uses include:
- Mathematical exponents: x² or a⁴
- Ordinal indicators: 1ˢᵗ, 2ⁿᵈ, 3ʳᵈ
- Footnote markers and academic citations
- Stylised social media usernames and bios
- Chemical notation and trademark symbols
Subscript
Subscript characters sit below the normal text baseline. Unicode provides subscript versions of all 10 digits and a subset of letters. Common uses include:
- Chemical formulas: H₂O, CO₂, C₆H₁₂O₆
- Mathematical sequences: xₙ, aᵢ
- Log bases: log₂, log₁₀
- Phonetic and linguistic notation
Why Some Characters Stay Unchanged
Unicode does not define superscript or subscript versions for every character. For superscript, all lowercase letters and all digits are covered. For subscript, only digits and a limited set of letters (a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, x) have Unicode equivalents. Any character without a match is kept as-is in the output.
Frequently Asked Questions
What is superscript text?
+Superscript text appears slightly above the normal baseline and is rendered smaller. In Unicode, many letters and numbers have dedicated superscript code points. These characters can be pasted anywhere Unicode is supported without needing HTML or special formatting.
What is subscript text?
+Subscript text appears slightly below the normal text baseline. Unicode provides subscript equivalents for all digits (0–9) and a limited set of letters. It is widely used in chemistry (H₂O), mathematics (xₙ) and phonetics.
Why do some letters not convert to subscript?
+Unicode only defines subscript equivalents for a specific subset of letters: a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, and x. All other letters have no Unicode subscript code point and are kept unchanged in the output.
Can I use superscript text on social media?
+Yes. Because these are actual Unicode characters and not HTML tags, they can be pasted into Twitter, Instagram, Facebook, YouTube, Discord, and most other platforms that support Unicode — which covers virtually every modern app and website.
What is the difference between superscript Unicode and HTML superscript?
+HTML superscript uses the <sup> tag and only works in HTML documents. Unicode superscript uses dedicated code points for each character, so the text is inherently superscript in any context — it works in plain-text fields, bios, captions, and anywhere Unicode is supported.
