Examples

Each example follows the selected range exactly. This tool changes characters; it does not interpret a formula.

Unicode includes complete subscript digits and a smaller set of Latin subscript letters. Unsupported characters stay readable and unchanged.

Digits: All digits convert in either mode.₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉
Symbols: Listed operators and parentheses convert character by character.₊ ₋ ₌ ₍ ₎
Letters: A limited lowercase set is available: a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, and x. Uppercase subscript letters are not available.
Not formula-aware: Input such as 10+2 converts every supported character. LiteralKit does not decide which part should be raised or lowered.

The shortest path stays visible and predictable on both desktop and mobile.

Choose the position
Open the Superscript or Subscript tool. The page URL remains the source of truth.
Enter plain text
Digits and listed symbols convert immediately. Turn on supported letters only when you need them.
Verify and copy
Check what changed, then copy the exact Unicode result into your destination.

Use real Unicode subscript when you need a lightweight, copyable alternative to rich-text formatting.

Chemical formulas: Turn H2O, CO2, and similar plain text into H₂O and CO₂ without opening an equation editor.
Variables and indices: Create short indices such as a₁ or x₂ in notes, messages, and documentation.
Teaching materials: Prepare copyable examples for worksheets, slides, and learning platforms that accept plain text.
Limited style text: Convert only the subscript letters Unicode actually defines; other letters remain unchanged.

Honest limits make the copied result easier to trust.

Does LiteralKit validate a chemical formula?

No. It converts listed characters but does not check chemistry, capitalization, charge, or formula structure.

Why are there fewer subscript letters?

Unicode defines a complete subscript digit set but only selected Latin letters. LiteralKit does not invent the missing ones.

Can I use the result in Word or Google Docs?

Usually, if the chosen font contains the needed glyphs. Rich-text subscript formatting is still preferable for professional document typography.

Why might another app show a box?

The destination device or font may not contain that Unicode glyph. Try a font with broad symbol coverage or use the app’s native formatting.
