b, c, d, f, g, q, w, y, and z have no single-character Unicode subscript in common fonts — they stay unchanged when letters are enabled.
Subscript preview
Your subscript output will appear here.
Unsupported characters remain unchanged, so your text stays readable.
A subscript generator converts normal characters into lowered Unicode equivalents — like ₀₁₂ for numbers or subscript letters for math and chemistry-style notation in plain text fields.
This Muxgen tool lets you choose exactly what converts: partial Latin letters, all digits, or math symbols. Characters without a Unicode subscript glyph stay readable at normal size — all processing runs locally in your browser.
Three simple steps to create lowered Unicode text.
Type or paste indices, formulas, or phrases in subscript-input.
Toggle letters, numbers (0-9), and symbols (+ - = ( )).
Copy subscript and paste into notes, bios, chats, or mockups.
Every control in the subscript generator component.
Textarea id subscript-input — six rows; starts empty.
options.letters — SUBSCRIPT_LETTERS partial a–z map.
options.numbers — ₀ through ₉ for digits 0-9.
options.symbols — ₊ ₋ ₌ ₍ ₎ for + - = ( ).
Spread input; mappedLetters ?? mappedNumbers ?? mappedSymbols ?? char.
Min-height 180px — live useMemo output.
Footer lists b c d f g q w y z unchanged.
Primary button with aria-label; disabled when output empty.
clearAll resets input and copied flag.
Flipping a checkbox clears copied state.
execCommand copy if clipboard API fails.
letters numbers symbols all true on load.
Maps, toggles, and partial letter coverage.
Seventeen Latin letters have dedicated subscript Unicode — not full alphabet.
All digits 0–9 convert when numbers checkbox is on.
Subscript plus, minus, equals, and parentheses for formula snippets.
Subscript only what you need — digits-only for chemical indices.
No Generate button — output updates while typing.
Unmapped characters stay normal size.
How this page fits next to other Unicode tools on Muxgen.
Lowered indices here; raised exponents on Superscript Generator.
Granular toggles here; three styles bundled on Small Text.
Pasteable plain text — not HTML <sub> markup.
Turn off letters for H₂O; turn off numbers for word-only lowering.
Formulas use numbers; bios may use available subscript letters.
Paste short samples in Discord, Notion, or CMS before long posts.

For H2O with numbers on and letters off, you get H, subscript ₂, and O — oxygen stays normal because O has no standard single-character subscript in Unicode.
