Lowered text, not a smaller font
What is subscript? It is text below the baseline: the 2 in H₂O, the 1 in x₁, or the 6 in C₆H₁₂O₆. Making the font smaller is not the same thing. Unicode lowered characters stay when you copy between Word, Google Docs, and chat.
Quick answer: Use it for chemical formulas and math indices. Type H2O in the free paste tool, copy, and paste.
When do you need it?
- Chemistry: H₂O, CO₂, NaCl, C₆H₁₂O₆
- Math indices: x₁, x₂, aₙ
- Physics: v₀ initial velocity
- Footnote-style markers: sometimes ₁ (superscript ¹ is more common for notes)
Students hit this most often in chemistry class when a worksheet says “write H2O correctly” and the chat app has no subscript button. A screenshot will not give classmates a pasteable ₂. Give them the character.
Ready formulas live on the chemistry formula board.
Why Word subscript dies in WhatsApp
Ctrl + = in Word lowers a normal 2 visually. Paste that sentence into WhatsApp and the 2 often returns to full size. The chat app never received a subscript character, only a style that lived inside Word.
₂ is U+2082. Once it is on the clipboard, most phones keep it below the line. If an old font shows a box, switch to a common system font. Do not shrink the point size and call it done.
Lab reports that never leave Word can keep Word formatting. The moment you copy into email, a LMS box, or a group chat, you need Unicode. That is what is subscript in practice on the web: a character that survives paste.
What it looks like in practice
| Use | Plain text | Lowered |
|---|---|---|
| Water | H2O | H₂O |
| Carbon dioxide | CO2 | CO₂ |
| Variable | x1 | x₁ |
Raised digits (x², E=mc²) are the opposite job. Compare: below the line vs above it.
Make lowered text in three steps
- Open the subscript generator (Subscript is already selected).
- Type plain H2O or CO2 with Formula mode and Numbers Only on, then Copy.
- Paste into Word, Docs, slides, or chat.
