How does the Subscript Generator work?
It replaces normal numbers and letters with their Unicode subscript equivalents where available. Some characters don’t have subscripts, so they’ll stay standard.
Where can I use subscript text?
Almost anywhere that accepts Unicode — from social media and chat apps to blog posts and emails.
Is this the same as HTML subscript?
Not exactly. HTML uses formatting tags like
<sub>, while this generator converts the characters directly so they can be pasted into plain-text fields.
Is it free to use?
Completely free, and always will be. No accounts or downloads required.
