What is a subscript generator?

A subscript generator lowers your characters into small subscript form, like the “2” in H₂O. Snabbit maps each supported letter, digit and symbol to its Unicode subscript character so you can paste formulas and footnotes into plain-text fields. It works in your browser, so nothing you enter is uploaded anywhere.

How to use the Subscript

  1. 1 Type text such as H2O or x1 into the input.
  2. 2 Supported characters are lowered into subscript.
  3. 3 Copy the subscript output.
  4. 4 Paste it into your document, chat or post.

What you can use it for

  • Writing chemical formulas in plain text.
  • Adding mathematical indices like x₁ or aₙ.
  • Posting footnote-style markers in chat.
  • Labelling variables in code comments.

Frequently asked questions

Why are some letters not converted?
Unicode only provides subscript forms for a subset of letters. Characters without a subscript version are left unchanged so the rest of your text stays readable.
Is this good for chemical formulas?
Yes. Digits all have subscript forms, so formulas like H₂O, CO₂ and C₆H₁₂O₆ display correctly in plain-text fields and chats.
Will subscript show on every platform?
Most modern apps render Unicode subscript. Very old systems may show a normal-size character, but the underlying subscript character is still there when copied.
