Subscript Generator
Transform your text into subscript Unicode characters that appear below the baseline.
How to Use the Subscript Generator
Convert any text to subscript Unicode characters that appear below the baseline. The converted text works in any application that supports Unicode, including social media, email, and plain text editors.
- Type or paste your text into the input field above.

What Is Subscript Unicode?
Subscript Unicode characters appear below the text baseline, positioned lower and smaller than regular text. They are part of the Unicode standard block "Superscripts and Subscripts" (U+2080 through U+209F) and are actual characters rather than formatting. This means they can be copied and pasted into any text field without losing their appearance.
Unlike HTML <sub> tags which only work in web pages, Unicode subscript characters work everywhere: social media bios, plain text emails, messaging apps, code comments, and any application that supports UTF-8 encoding. The standard includes subscript versions of all digits (₀ through ₉) and select letters including a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, and x.
Common Uses for Subscript
- Chemistry: Write molecular formulas in plain text — H₂O (water), CO₂ (carbon dioxide), CH₄ (methane), C₆H₁₂O₆ (glucose).
- Mathematics: Express indices, sequences, and logarithmic bases like xₙ, a₁, log₂, and summation variables.
- Physics: Write initial and final state variables such as v₀ (initial velocity), aₓ (x-component of acceleration), T₁ (initial temperature).
- Programming: Represent array indices and sequence elements in documentation and comments.
- Social media: Create a "whisper" effect or add subtle annotations using subscript text on Instagram, Discord, and Twitter.
Subscript vs Superscript
| Feature | Subscript | Superscript |
|---|---|---|
| Position | Below the baseline | Above the baseline |
| Unicode range | U+2080-209F | U+2070-207F |
| Primary use | Chemistry, indices | Exponents, footnotes |
| Example | H₂O, xₙ | x², 10³ |
| Letter coverage | 17 letters | Most lowercase letters |
Frequently Asked Questions
<sub> tag to visually lower text on web pages, but the text is still regular characters with formatting applied. Unicode subscript uses actual subscript characters from the Unicode standard that are inherently small and lowered. Unicode subscript works in plain text fields where HTML formatting is not supported, such as social media and messaging apps.
<sub> tags instead of Unicode subscript characters.
