Subscript Generator
Convert text into small, lowered subscript characters for things like H₂O or footnote-style notation. These are genuine Unicode characters you can copy and paste, so only the digits and letters that exist as subscripts can be converted — everything else can be kept or removed.

Subscript support in Unicode is limited, so results often mix small and normal characters.
Frequently asked questions
Which characters can be converted?
All digits and a limited set of lowercase letters have Unicode subscript forms. Many letters do not, so they cannot be converted.
What about unsupported characters?
Choose to keep or remove them. Keeping is the default so your text stays intact.
Can I write chemical formulas?
You can produce subscript numbers like H₂O, but this is plain text, not a formatted formula editor.
Is my text private?
Yes. Everything is converted in your browser and never uploaded.
