How this Subscript Generator works

This Unicode text transformation tool converts standard characters into subscript equivalents using specialized Unicode code points designed for mathematical and chemical notation. The converter maps numbers (0-9 → ₀-₉), select lowercase letters (a,e,h,i,j,k,l,m,n,o,p,r,s,t,u,v,x → ₐ,ₑ,ₕ,ᵢ,ⱼ,ₖ,ₗ,ₘ,ₙ,ₒ,ₚ,ᵣ,ₛ,ₜ,ᵤ,ᵥ,ₓ), and mathematical operators (+,-,=,parentheses).

Real-time conversion processes input character-by-character, immediately displaying results in the output field. The system identifies unconvertible characters—letters like b,c,d,f,g,q,w,y,z lack official Unicode subscript equivalents—and displays warnings listing which characters couldn't transform. This transparency helps users understand Unicode subscript limitations versus CSS-based styling.

Output text copies directly to clipboard for pasting into documents, social media, messaging applications, or anywhere Unicode renders correctly. Common applications include writing chemical formulas (H₂O, CO₂), mathematical indices (xₙ, aᵢⱼ), footnote references, or stylized social media text. Unlike CSS subscript styling which only works in specific contexts, Unicode subscripts paste correctly across platforms, browsers, and applications including plain text environments.

Frequently Asked Questions

What characters can be converted?
All numbers (0-9), some letters (a,e,h,i,j,k,l,m,n,o,p,r,s,t,u,v,x), and symbols (+,-,=,(,)).
Why can't all letters be converted?
Unicode only defines subscript versions for a limited set of characters. Letters like b,c,d,f,g,q,w,y,z don't have official subscript equivalents.
Where can I use subscript text?
Subscript works in most browsers, social media, documents, and messaging apps that support Unicode.
Is this real subscript or just small text?
This uses real Unicode subscript characters, not CSS styling, so they paste correctly everywhere.
