Subscript Generator
Convert text to Unicode subscript characters online for free. Enter any text to generate subscript letters, numbers, and symbols with instant copyable output and character-by-character breakdown.
About This Calculator
The Subscript Generator converts any text into Unicode subscript characters that stay formatted no matter where you paste them. Whether you need to write chemical formulas like H₂O, mathematical indexes like x₁, x₂, x₃, or create aesthetic text for social media profiles, this free online tool transforms your text instantly using real Unicode subscript characters.
Unlike formatting in a word processor (which only visually transforms characters and loses the effect when pasted into plain-text environments), this generator uses actual Unicode subscript characters (U+2080-U+209C and U+1D62-U+1D65) that preserve their appearance in any Unicode-compatible environment — including web browsers, email clients, messaging apps, social media platforms, and plain-text documents. Each character is mapped to its dedicated Unicode code point; characters without a subscript equivalent are left unchanged and clearly marked in the breakdown table.
Subscript Unicode coverage includes all ten digits (0-9), common math symbols (+, -, =, Parentheses), and a subset of lowercase letters: a, e, h, i, k, l, m, n, o, p, r, s, t, u, v, x. Uppercase letters and most other lowercase letters do not have Unicode subscript versions and will remain at full size. The character-by-character breakdown table shows exactly which characters were converted and which were left unchanged.
Regional Notes
Global: Unicode subscript characters are supported on virtually all modern devices and platforms including Windows, macOS, iOS, Android, and Linux. The converted text works in web browsers, email clients, messaging apps, and social media platforms that support Unicode. No special software or font installation is required.
Frequently Asked Questions
How does the Subscript Generator work?
Type or paste your text into the input box and click Convert. Each character is mapped to its Unicode subscript equivalent. Characters without a Unicode subscript equivalent remain in their original form and are marked as unchanged in the breakdown table.
What characters can be converted to subscript?
All ten digits (0-9) have subscript versions. Subscript letters include a, e, h, i, k, l, m, n, o, p, r, s, t, u, v, x. Common math symbols like +, -, =, (, ) also have subscript characters. Uppercase letters and most lowercase letters (b, c, d, f, g, j, q, w, y, z) do not have dedicated Unicode subscript code points and are left unchanged.
What is the difference between subscript and superscript?
Subscript characters appear below the normal text baseline (e.g., H₂O), while superscript characters appear above the baseline (e.g., x²). Superscript has broader Unicode coverage with most letters available, while subscript only covers a subset of lowercase letters plus all digits and a few symbols.
Is this Subscript Generator free to use?
Yes, it is completely free to use with no registration or hidden charges. You can convert unlimited text to subscript characters.
Why are some characters not available in subscript?
The Unicode Consortium only created subscript characters for symbols commonly used in scientific and mathematical writing. Letters and symbols that are rarely needed as subscripts were not given their own Unicode code points. The converter leaves these characters in their original form and marks them in the breakdown table.
How do I write subscript in Word or Google Docs?
In Microsoft Word, use the x₂ button in the Home tab or press Ctrl+= (Windows) or Cmd+= (Mac). In Google Docs, select your text and press Ctrl+, (Windows) or Cmd+, (Mac). This generator is useful when you need subscript characters that stay formatted even in plain-text environments like URLs, social media, and messaging apps.
Can I share my subscript conversion results?
Yes, the URL automatically saves your input text. You can bookmark or share the link to revisit the exact conversion.
Where are subscript characters commonly used?
Subscript is used in chemical formulas (H₂O, CO₂), mathematical sequences and indexing (x₁, x₂, x₃), scientific notation, and for aesthetic text styling on social media profiles and posts.
