Subscript Generator — Unicode Subscript Text Converter

Instantly convert numbers, letters, and symbols to their Unicode subscript equivalents (₀–₉, ₐ, ₑ, ₒ…). Copy the result and paste it anywhere that accepts Unicode — documents, emails, social media, or code comments.
Digits, +, -, =, (, ) and letters a e h i k l m n o p s t u v x are converted; others pass through unchanged
Supported subscript characters: 0–9, +, −, =, (, ), and letters: a e h i k l m n o p s t u v x (and Greek β γ ρ φ χ). Uppercase letters are lowercased where a subscript form exists.

Quick answer

How does this calculator work?

Type your text — digits, +, −, =, (, ), and the letters a e h i k l m n o p s t u v x are swapped for their Unicode subscript equivalents (₀₁₂ₐₑₒ…). Other characters pass through unchanged. Copy the result and paste it anywhere Unicode is supported. No font or markup needed — works in plain text.

Formula
No formula — character substitution from the Unicode Subscript block (U+2080–U+209C) and related codepoints
How this is calculated

Unicode includes a dedicated Subscript block (U+2080–U+209C) containing subscript digits 0–9, the operators +, −, =, (, and ), and a set of subscript letters. The subscript letter coverage in Unicode is limited by design — only those letters that appear frequently in mathematical and scientific notation were standardised: a, e, h, i, k, l, m, n, o, p, s, t, u, v, x, and the Greek letters β, γ, ρ, φ, χ.

For digits and operators, conversion is complete — every digit 0–9 has a subscript counterpart. For letters, uppercase input is mapped to the equivalent lowercase subscript form when one exists. Letters without Unicode subscript equivalents (such as b, c, d, f, g, j…) are passed through unchanged, so the output may be a mix of subscript and normal characters for text containing unsupported letters.

The generated text is plain Unicode and works in any environment that supports UTF-8 — which includes virtually all modern operating systems, browsers, and apps. However, some fonts do not include the full Unicode subscript range; if you see squares or question marks, try a font like Arial Unicode, Noto, or Segoe UI that has broad Unicode coverage.

Frequently asked questions

The Unicode Consortium added only those subscript letters that appear in established scientific, phonetic, or mathematical notation — primarily those used in IPA (International Phonetic Alphabet) and chemistry. Letters like b, c, d, f, g, j, q, r, w, y, z have no standardised Unicode subscript forms. For full subscript text in documents, use the subscript formatting in your word processor (Ctrl+= in Word/Google Docs), which renders any character below the baseline.

HTML <sub> tags and CSS vertical-align: sub visually lower any character below the baseline by shrinking and repositioning it — but the characters are still the same codepoints, so they paste as normal text. Unicode subscript characters are separate codepoints that look like subscripts in all contexts, including plain text, SMS, and social media, without any markup — but only the limited set above is available.

Yes. Because the result is plain Unicode text, it can be pasted wherever you can type: Twitter/X, Instagram, WhatsApp, Telegram, Gmail, Outlook, and most other platforms. Font support may vary — if a character appears as a box, the recipient’s device lacks a font with that glyph, though modern smartphones and computers support the full subscript block.
