- •Best for chemistry, math, physics, and indexing notation.
- •The surrounding sentence can be in any language, but only supported characters will change.
- •Ideal for copy-paste formulas in notes, chats, posts, and documents.

Is this tool free?
Yes, completely free. No sign-up required.
Where can I paste the output?
Anywhere that supports Unicode — social media, emails, documents, messaging apps, and more.
Why are some letters missing in subscript?
Unicode only defines subscript versions for a limited set of letters (a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, x). Letters without subscript equivalents will remain unchanged.
Why can only some letters become subscript?
Unicode only defines subscript and superscript variants for a limited number of letters, so unsupported letters remain unchanged.
Does the page language affect the result?
No. The page language only changes the UI. Whether a character converts depends on whether Unicode has a matching variant.
What is this tool best for?
It is best for chemistry, math, physics, formulas, and sequence notation, not general text styling.
