Subscript Generator for Chemistry (CO₂, H₂O, C₆H₁₂O₆)
Chemistry formulas are one of the most common uses of subscript text. Use this subscript generator to quickly format CO₂, H₂O, C₆H₁₂O₆, and more. Type the plain formula (CO2, H2O, C6H12O6), set Formula mode with Numbers Only: On, then copy the result.
- CO2 → CO₂
- H2O → H₂O
- C6H12O6 → C₆H₁₂O₆
What Is a Subscript?
A subscript is a character, letter, or number that sits below the normal baseline. Unicode subscript characters use real subscript font (not images or styling) so they copy and paste correctly.
- Chemical formulas (H₂O, CO₂, C₆H₁₂O₆)
- Mathematical notation (x₁, aₙ, variables)
- Scientific notation and equations
- Footnote references and indices
- Molecular formulas in documents
How to Use the Subscript Generator
This subscript and superscript generator is designed to be easy for everyone. Follow the steps below to format your text perfectly. Use subscript for chemistry formulas (subscript chemistry) and math; use superscript for exponents. Small text and tiny numbers copy paste modes are also available.
Step 1: Choose a Conversion Type
Select the style you want for your text. You can switch anytime.
- Subscript – Characters sit below the baseline (e.g. H₂O, CO₂, x₁). Best for chemistry, math variables, and scientific notation.
Extra features:
- Superscript – Characters sit above the baseline (e.g. x², E=mc²). Superscript copy paste works the same way. Best for exponents and footnotes.
- Small Text – Uses modifier letters for compact styling.
Tip: Subscript is best for chemical formulas. Superscript is best for exponents and powers.
Step 2: Choose a Conversion Mode
At the top of the center panel, you will see two modes. Each works differently.
- Formula mode – Converts only numbers that immediately follow letters. Ideal for subscript chemistry and math formulas.
- Input: H2O, CO2, C6H12O6
- Output: H₂O, CO₂, C₆H₁₂O₆
- Full mode – Converts every supported letter and number. Use when you want whole words or mixed text in subscript/superscript.
- Input: hello, x1n2
- Output: ₕₑₗₗₒ, ₓ₁ₙ₂
Tip: For H₂O, CO₂, and similar formulas, always use Formula mode.
Step 3: Set Numbers Only
This option controls whether letters are converted or only numbers.
- Numbers Only: ON – Only digits convert (H2O becomes H₂O; letters stay normal). Use for chemistry formulas.
- Numbers Only: OFF – Letters and numbers both convert. Use for full subscript text (e.g. xₙ, aₘ).
Step 4: Enter Your Text
Click inside the input box and type or paste your content. You can write:
- Chemical formulas (H2O, CO2, H2SO4)
- Mathematical expressions (x1, x2, an)
- Physics equations (E=mc2)
- Normal text with numbers
You can also use Upload File to load text from a .txt file.
Step 5: Use Quick Example Buttons
Above the tool, use the built-in buttons to insert formatted examples instantly:
- H₂O (water)
- CO₂ (carbon dioxide)
- x₂ (variable with subscript)
- C₆H₁₂O₆ (glucose)
Clicking a button inserts the plain input (e.g. H2O) and converts it automatically.
Step 6: Use Auto or Click Generate
With Auto: ON, the output updates as you type. No need to click anything.
With Auto: OFF, click the Generate button to convert. The Generate button applies the conversion on demand.
Tip: Use Auto ON for quick edits. Use Auto OFF if you prefer to control when conversion happens.
Step 7: Customize for Word and Google Docs (Optional)
If you will paste into Word or Google Docs, you can tick Bold or Italic before copying. The pasted text will keep that formatting. These options do not work in social media or .txt files.
Step 8: Copy or Download the Result
Click Copy to Clipboard to copy the formatted text, or use the Copy button in the output panel. Click Download to save as a .txt file.
Paste the result into Word, Google Docs, email, social media, or any app that supports Unicode.
Clear Input or Reset (If Needed)
Click Clear in the input panel to empty the input box. Click Reset to clear both input and output and start fresh.
Subscript Symbol (Copy and Paste)
Each subscript symbol below is a real Unicode character. Copy subscript numbers (₀–₉) and letters (ₐ–ₓ) from the tables in the next sections. Paste into Word, Excel, PowerPoint, Discord, WhatsApp, or any app that supports Unicode.
Subscript 0–9 Copy and Paste
Unicode subscript numbers 0–9 (U+2080 to U+2089). Select and copy any character below to use as subscript 0, subscript 1, subscript 2, and so on.
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|---|
| ₀ | ₁ | ₂ | ₃ | ₄ | ₅ | ₆ | ₇ | ₈ | ₉ |
Use these digits to build math indices and chemistry formulas like x₁, x₂, x₃ or CO₂ and H₂O. For a full sentence or word in subscript, switch the tool to Full mode.
Subscript Letters (Unicode Reference)
Subscript letters copy and paste as real Unicode characters. Letters b, f, and q have no Unicode subscript form, which is why there is no dedicated subscript B or subscript f character in Unicode. When you need them, use regular letters with formatting in Word or PowerPoint, or write variables such as B₁ and fₙ instead.
| a | e | h | k | l | m | n | o | p | s | t | x |
|---|---|---|---|---|---|---|---|---|---|---|---|
| ₐ | ₑ | ₕ | ₖ | ₗ | ₘ | ₙ | ₒ | ₚ | ₛ | ₜ | ₓ |

Subscript vs Superscript
Subscript sits below the baseline; superscript sits above it.
| Type | Position | Example |
|---|---|---|
| Subscript | Below baseline | H₂O, CO₂, x₁ |
| Superscript | Above baseline | x², E=mc² |

Frequently Asked Questions
What is a subscript generator?
A subscript generator converts plain text into Unicode subscript characters. Paste the result into Word, Google Docs, or any app.
How do I write H2O or CO2 in subscript?
Type H2O or CO2 in the tool, select Formula mode with Numbers Only ON, then click Generate. Copy the output (H₂O or CO₂) and paste it into your document, slide, or chat.
How do I copy and paste subscript text?
Type or paste your text into the input box, choose Subscript, then click Copy. The tool converts the characters to Unicode subscript so you can copy and paste them anywhere that supports Unicode.
How do I use subscript text in WhatsApp?
Generate the subscript version of your text here, tap Copy, then paste it into your WhatsApp message. WhatsApp does not have a formatting button for subscript, but it displays Unicode subscript characters correctly on modern devices.
Why is there no subscript B or subscript f?
The Unicode standard does not define characters for subscript b, subscript f, or subscript q. To simulate them, use normal letters with formatting in Word or PowerPoint, or combine letters with subscript numbers such as B₁ and fₙ.
