Subscript Generator result
Subscript lowers characters below the normal line, most familiar from chemical formulas like H₂O. This tool converts full words and numbers into Unicode's subscript characters directly.
Unicode added subscript characters mainly to support scientific notation — chemical formulas, mathematical indices, and similar technical writing — which is why coverage of the full alphabet is incomplete.
Only a subset of lowercase letters (a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, x) have subscript equivalents in Unicode. Letters like b, c, d, f, g, q, w, y, and z simply don't exist in subscript form, so they're left unchanged.
For anything read by assistive technology or meant to be indexed by search engines, the semantic <sub> tag is the more reliable choice — reach for this generator specifically for platforms that strip HTML formatting.
Subscript coverage in Unicode is incomplete — only about two-thirds of the lowercase alphabet has a subscript form, so unsupported letters stay at normal size.
Yes for the numbers (which are fully supported); for letters, results will vary depending on which specific letters appear in the formula.
No — Unicode's subscript letter set only covers lowercase, so uppercase input is converted to lowercase before styling.
