Subscript Generator
Turn text and numbers into lowered subscript characters.
Lowered text without formatting
Subscript is essential for chemistry and maths, but many text fields do not support it. Unicode provides small lowered characters for digits and some letters, usable as plain text.
Enter your text and the tool lowers every supported character; the rest stay as they are. It is the simplest way to write H₂O or an index in a place that only accepts plain characters.
Plain-text and private
The conversion runs in your browser, so your text is never uploaded.
Frequently Asked Questions
How does it work?
It maps characters to their Unicode subscript forms, which are ordinary text you can paste anywhere, not formatting.
Why are some characters unchanged?
Unicode defines subscript forms only for digits and a limited set of letters. Anything without one is left unchanged.
What is it good for?
Chemical formulas like H₂O, mathematical indices, and stylized text where real subscript is not available.
