Subscript & Superscript Text Generator

Subscript & Superscript Text Generator

Turn regular text into copyable Unicode subscript and superscript characters in seconds. Use this free subscript and superscript text generator for simple math expressions, chemical formulas, units, reference numbers, social media captions, usernames, and short notes.

Enter your text, then copy the subscript or superscript version you need. For example, convert x2 into x², H2O into H₂O, CO2 into CO₂, or 10-3 into 10⁻³.

How to use the subscript and superscript generator

1. Type or paste your regular text into the input box.
2. Review the instant superscript and subscript results.
3. Copy the version you need.
4. Paste it into your message, document, social media profile, caption, website draft, or design tool.

The tool converts available characters while keeping unsupported characters visible. This helps you avoid copying inaccurate replacements.

What is superscript text?

Superscript text uses smaller characters raised above the normal text line. It is commonly used for powers, ordinals, references, and scientific notation.

Common examples include:

• x² for “x squared”
• m³ for cubic metres
• 1ˢᵗ for an ordinal number
• 10⁻³ for scientific notation
• aⁿ for algebraic expressions

Superscript characters are useful when you need simple notation in a place where a normal keyboard does not provide a quick formatting option.

What is subscript text?

Subscript text uses smaller characters positioned below the normal text line. It is often used in chemistry, mathematics, science, and variable naming.

Common examples include:

• H₂O for water
• CO₂ for carbon dioxide
• a₁ for a first indexed variable
• xₙ for a numbered sequence
• O₂ for oxygen

Subscript is especially useful for short formulas, chemical names, units, and classroom notes.

Copy and paste Unicode subscript and superscript text

This tool uses Unicode characters rather than visual styling. That means the converted text can usually be copied and pasted into many apps, including social platforms, chat apps, document editors, and website fields.

You can use the output for:

• Instagram, TikTok, Facebook, X, WhatsApp, and Discord
• Google Docs and basic text editors
• Social media bios and usernames
• Educational worksheets and quick notes
• Product captions and marketing copy
• Simple scientific, mathematical, and chemical references

Always test the final text on the platform where you plan to publish it. Some fonts, apps, and older devices may display certain Unicode characters differently.

Unicode subscript and superscript limitations

Unicode does not include a complete subscript or superscript alphabet. Numbers and common mathematical signs have strong support, but many letters, symbols, and punctuation marks do not have an exact Unicode equivalent.

For that reason, this generator:

• Converts only characters with suitable Unicode forms
• Keeps unsupported characters unchanged
• Identifies characters that could not be converted
• Avoids replacing characters with misleading lookalikes

For example, most numbers can be converted to both subscript and superscript. However, only a limited set of letters is available in true subscript form.

Unicode text vs proper document formatting

Unicode subscript and superscript are useful for short, copyable text, but they are not a replacement for professional typesetting.

For websites, important documents, accessibility-focused content, or complex formulas, use proper semantic subscript and superscript formatting, an equation editor, MathML, or LaTeX where available.

Unicode text is best for short content such as:

• x²
• H₂O
• CO₂
• cm³
• 1ˢᵗ
• 10⁻³

For a long scientific equation, a research paper, or an accessible educational resource, use an appropriate equation-formatting tool instead.

Examples of subscript and superscript text

Is subscript and superscript text accessible?

Decorative Unicode text can be difficult for screen readers to interpret, especially when it is used for long phrases, usernames, or full paragraphs. Keep important content in standard text where clarity matters.

For educational materials, websites, forms, and technical documents:

• Use standard text for full sentences.
• Use proper formatting tools for important equations.
• Add clear labels when notation may be ambiguous.
• Avoid using decorative Unicode as the only way to communicate essential information.

Does this tool store my text?

No. Your text is converted locally in your browser. The tool does not require an account, and it does not save your input.

Frequently asked questions

Can I create x squared with this tool?

Yes. Enter x2, then copy the superscript result: x².

Can I make H₂O or CO₂ text?

Yes. Enter H2O or CO2, then copy the subscript output to create H₂O or CO₂.

Why do some letters stay unchanged?

Unicode does not provide an official subscript or superscript character for every letter. The tool leaves those characters unchanged so your text remains accurate.

Can I use this text on Instagram or WhatsApp?

Usually, yes. Unicode text can be pasted into many social media and messaging platforms. Check the result on the destination platform before publishing.

Is Unicode superscript suitable for complex equations?

Not usually. For complex equations, use an equation editor, MathML, or LaTeX instead of copy-and-paste Unicode characters.
