Subscript Generator – Copy & Paste Subscript Text Online

This free online Subscript Generator converts normal text into real Unicode subscript characters instantly, so you can copy and paste subscript text anywhere. Create subscript text for math formulas, chemistry equations, indexed variables, and technical writing — then copy and paste the result anywhere.

Whether you need subscript letters like ₐ or ₓ, subscript numbers such as ₂ and ₁, or expressions like H₂O, CO₂, x₁, or T₁₆, this online subscript generator makes it fast, accurate, and easy.

Updated February 2026 — improved Unicode subscript generator with expanded letter and number support.

Copy & Paste Subscript Characters

Numbers: ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉

Letters: ₐ ₑ ₕ ᵢ ₓ

Tip: Click Convert to generate subscript text you can copy and paste instantly.

What Is Subscript Text?

Subscript text appears slightly below the normal baseline and is commonly used in mathematics, chemistry, physics, and scientific notation.

This subscript generator creates real Unicode subscript text rather than visual formatting. That means you can copy and paste subscript text into Google Docs, Microsoft Word, emails, messaging apps, and most modern websites without losing formatting.

Subscript Letters (Copy & Paste)

Many users search for subscript letters copy and paste. Unicode includes several official subscript letters, although it does not provide a complete A–Z subscript alphabet.

Supported Latin subscript letters include: ₐ ₑ ₕ ᵢ ⱼ ₖ ₗ ₘ ₙ ₒ ₚ ᵣ ₛ ₜ ᵤ ᵥ ₓ.

Supported Greek-style subscript letters include: ᵦ ᵧ ᵨ ᵩ ᵪ.

If a letter does not have a Unicode subscript equivalent, this subscript text generator leaves it unchanged to maintain accuracy and compatibility.

Subscript Numbers (₀–₉)

Subscript numbers are fully supported in Unicode and are widely used in chemical formulas and indexed variables.

₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉

Examples include H₂O, CO₂, x₁, and a₀.

If you searched for subscript 2, subscript numbers generator, or copy and paste subscript numbers, this tool provides ready-to-use Unicode subscript text instantly.

Subscript Generator for Math Formulas

In mathematics, subscripts are used for indexing and notation, such as x₁, aₙ, T₁₆, or q₀.

This online subscript generator converts supported characters individually, allowing you to quickly create mathematical subscript text without special editors.

Note: This tool converts standard text into Unicode subscript characters and does not interpret LaTeX commands.

Subscript in Chemistry

Chemistry relies heavily on subscript numbers to represent atomic quantities in molecules and ions.

Use this subscript text generator to format H₂O, CO₂, NH₄⁺, and SO₄²⁻ without equation editors.

Note: Ionic charges such as ²⁻ require superscript formatting. You can use a superscript generator for charge notation.

Alt Code for Subscript 2 (Unicode Alternative)

Many users search for the alt code for subscript 2. Traditional Windows ALT codes do not reliably support Unicode subscript characters like ₂.

Instead of relying on inconsistent alt codes, use this subscript generator to create subscript 2 and other characters, then copy and paste the result.

This method ensures compatibility across operating systems, browsers, and applications.

Subscript vs Superscript

Subscript text appears below the baseline (H₂O), while superscript appears above it (x²).

If you need exponent formatting or ionic charges, use our Superscript Generator.

Both tools create Unicode characters for reliable copy-and-paste formatting.

Why Unicode Subscript Works Everywhere

Unicode subscript characters are defined in the Unicode standard as plain text characters, which is why this subscript generator works reliably across modern apps.

Because they are not styling effects, they can be copied, pasted, downloaded, and shared without losing formatting.

Most modern fonts and browsers support Unicode subscript numbers and letters natively.

Limitations of Subscript Letters

Unicode does not provide a complete subscript alphabet.

Only specific letters and symbols have official subscript forms.

This subscript generator converts supported characters and leaves unsupported characters unchanged to preserve accuracy.

How to Use This Subscript Generator

1. Enter your normal text in the input box.

2. Click Convert to generate subscript text.

3. Copy and paste the subscript output wherever you need it.

You can also download your subscript text as a file and optionally include the original input.

Frequently Asked Questions

What is a subscript generator?

A subscript generator is an online tool that converts normal text into Unicode subscript characters so you can copy and paste subscript text anywhere.

How do I type subscript 2?

The easiest way to type subscript 2 is to use this tool to convert the number 2 into ₂ and copy and paste it. Windows ALT codes do not reliably support Unicode subscripts.

Why don't all letters convert to subscript?

Unicode only defines subscript versions for certain letters and symbols. Characters without official subscript forms remain unchanged.

Can I copy and paste subscript text into Google Docs?

Yes. Because this tool generates real Unicode subscript characters, you can copy and paste them into Google Docs, Microsoft Word, emails, and most websites.

What's the difference between subscript and superscript?

Subscript appears below the baseline (H₂O), while superscript appears above it (x²). They are used for different mathematical and scientific purposes.

How do I copy and paste subscript text?

Generate your subscript text using this subscript generator, click Copy, and paste it into your document or website. Because the output uses Unicode characters, the formatting remains intact in most modern applications.

Is there an alt code for subscript numbers?

Traditional Windows ALT codes do not consistently support Unicode subscript numbers such as ₂ or ₃. The most reliable method is to use a subscript generator and copy and paste the character directly.
