How do I make subscript text?

Type your text and it is converted into Unicode subscript characters — small lowered letters and numbers. Tap Copy and paste them anywhere as real characters, no font required.

Can I write chemical formulas like H₂O?

Yes. All digits 0–9 have subscript forms, so you can type H2O or CO2 and copy the properly formatted H₂O and CO₂ for posts, chats, and notes.

Why are some letters not converted?

Unicode only defines subscript characters for the digits and a limited set of letters, so letters without a subscript form (such as b, c, d, and q) stay at normal size.

Is it free and private?

Yes. Everything runs in your browser with no sign-up, and nothing you type is uploaded or stored.

Subscript Generator

Turn letters and numbers into small lowered subscript characters — perfect for chemical formulas like H₂O and CO₂ — that you can copy and paste anywhere.

Tap Copy on any style, then paste it into Instagram, TikTok, Discord, your bio, or anywhere.

What is a subscript generator?

A subscript generator turns your text and numbers into small, lowered characters — the little numbers in chemical formulas like H₂O and CO₂, or footnote-style markers. You type normally and copy real Unicode subscript characters that paste anywhere, with no formatting button required.

How to use it

Type your text or numbers in the box.
Tap Copy.
Paste the lowered subscript text into your post, document, or chat.

Chemical formulas made easy

Every digit 0–9 has a subscript form, so typing H2O, CO2, or C6H12O6 gives you the properly formatted H₂O, CO₂, and C₆H₁₂O₆. That is ideal for chemistry notes, science posts, and messages where a real subscript reads far better than H2O.

Subscript letters and symbols

Unicode also includes a limited set of subscript letters (such as ₐ, ₑ, ₒ, ₓ) and the symbols + − = ( ). Letters without a subscript form in Unicode (like b, c, d, and q) stay at normal size — a limitation of the character set rather than the tool.

Why it works anywhere

The lowered characters are real Unicode, not a font, so they survive copy-paste into Instagram, Discord, Google Docs, spreadsheets, and most apps. For raised characters instead, use the Superscript Generator, or explore the Fancy Text Generator for more styles.

Free and private

Everything runs in your browser. The subscript generator is free, needs no sign-up, and never uploads or stores what you type.
