It's handy for math notation, chemical formulas, or styled text for social media bios and messages, and every conversion happens right in your browser so nothing you type is sent to a server.

FAQ
- Will every character convert correctly?
- Not always. Unicode only defines a limited set of superscript and subscript characters, so some lowercase letters (like c, d, f, g) and most uppercase letters have no subscript equivalent. Those characters stay as-is unless you enable the exclude option.
- Can I paste the result anywhere?
- Yes, since it produces real Unicode characters, you can paste it into messaging apps, social media, or documents as long as the font supports those glyphs.
- Is my text stored anywhere?
- No. All conversion happens locally in your browser, and nothing is sent to or saved on a server.
