Subscript text sits below the normal text baseline, appearing smaller and lowered. Our generator converts characters to their Unicode subscript equivalents where available. These are real characters in the Unicode standard, not formatting tricks, so they copy and paste reliably.
Chemical formulas are the classic subscript use case. H2O for water and CO2 for carbon dioxide look right only with properly subscripted numbers. Our tool handles all digits zero through nine, so you can write out any chemical formula accurately.
The subscript alphabet is more limited than superscript. Unicode includes subscript versions for letters a, e, h, i, j, k, l, m, n, o, p, r, s, t, u, v, and x, plus all numbers and some mathematical symbols. Missing letters stay at normal size in your converted text.
Creative uses include aesthetic formatting for social media profiles, phonetic notation, and mathematical expressions with subscript variables. Some people combine subscript with other Unicode text styles for elaborate bio designs. The lowered position creates visual contrast against normal text.
Copy the subscript text from our tool and paste it into Instagram, Twitter, Facebook, or any app that accepts text. The characters display correctly on all modern devices since they are part of the international character standard. Test by pasting into your notes app first.
