Subscript, Straight From Unicode — No Formatting Required
Type your text and every character is swapped for its lowered Unicode subscript equivalent, sitting slightly below the normal line — the same effect used in chemical formulas like H₂O and mathematical notation, but as plain text rather than HTML formatting.
Because the output is real Unicode rather than a special font or a <sub>
tag, it survives being pasted into plain-text fields like social bios, usernames, and chat
messages that strip HTML.
What characters convert to subscript?
Unicode defines a subscript form for all 26 letters, digits 0–9, and five math symbols (+ − = ( )). Not every letter has a genuine dedicated subscript glyph — c, f, g, w, y, and z fall back to their superscript form as the closest available visual match, since Unicode never defined true subscript versions of those six letters. Every other letter uses a real subscript glyph, and capital letters convert using the same form as lowercase, since Unicode has no separate uppercase subscript series.
What's the difference between subscript and superscript?
Both shift characters away from the baseline, just in opposite directions. Subscript lowers characters below the line, as in chemical formulas like H₂O or CO₂. Superscript raises them above the line, the standard style for exponents (x²) and footnote markers. Both use complete Unicode ranges for letters, digits, and the same five math symbols.
How do I type subscript on my phone?
Most phone keyboards have no dedicated subscript key, and neither Android nor iOS offers a built-in shortcut for it. Typing your text into this generator and copying the result is the simplest way to get subscript text on any device.
Does this affect screen readers or accessibility?
It can. Subscript Unicode characters may be announced by their formal Unicode name rather than as normal letters, which can be confusing for screen reader users. For content that needs to be reliably accessible, use your platform's built-in subscript formatting instead of Unicode characters.
