Subscript Text Generator

Convert Unicode-supported lowercase letters `a e h i j k l m n o p r s t u v x`, all digits, and `+ - = ( )` into copyable subscript characters. For example, `x2+1` becomes `ₓ₂₊₁`; uppercase letters, unsupported lowercase letters such as b, c, or y, accents, emoji, spaces, and other punctuation remain unchanged. Unicode does not provide a complete matching subscript alphabet, so mixed baseline output is expected. This is not semantic chemical or equation markup, HTML `<sub>`, or a font effect. Rendering, search, accessibility, and support vary by app; conversion stays local.

Type or paste text into the Subscript Text Generator box; the result appears instantly and a copy button sends it straight to your clipboard.

The result is plain Unicode text, so its shape depends on the destination's font — most current apps render it fine, but very old software can show empty boxes.

Some platforms count these characters differently toward length limits than plain ASCII, and a few spam filters flag unusual Unicode more readily — preview the result first.

Read the output before publishing it and keep the plain original text handy in case a platform strips or mis-renders the styled version.

If Subscript Text Generator isn't quite the look you want, this collection also has the Superscript Text Generator and Wide Text Generator for the same input.

Every conversion happens locally in your browser; the text you type is never uploaded, logged, or stored by this tool.
