Drop your letters and numbers below the line — perfect for chemistry formulas, footnotes, and stylized captions.

Yes — type something like "H2O" and the numbers convert to subscript, giving you H₂O-style formatting you can copy straight into notes or documents.
Unicode only defines subscript characters for a limited set of letters plus all digits 0–9. Letters without a subscript equivalent are shown in their normal form.
It's real Unicode, not an image, so it pastes cleanly into almost any app — though a few older systems may not render every character.
Subscript sits below the baseline (H₂O, CO₂), while superscript sits above it (x², eᵏ). This tool handles subscript; the tiny text generator offers both superscript and subscript in one place if you need to mix them.
Subscript text sits slightly below the normal text line, like the "2" in H₂O. This tool maps your letters and numbers onto the Unicode subscript block, so the result is real text — not an image — and pastes cleanly into chemistry notes, footnotes, math formulas, or stylized captions on any platform that supports Unicode.
Unicode includes official subscript code points for the digits 0–9, the lowercase letters a, b, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, x and several Greek letters such as alpha and beta. Letters like c, d, f, g, q, w, y and z have no official subscript form, so this tool leaves them as-is instead of inventing a fake glyph. That's why real formulas — like chemical equations — rely on this exact character set.
