Why this tool exists
Typing x² in a document editor is easy when the editor has a superscript button. The trouble starts when the destination is a username field, plain-text message, spreadsheet label, or social profile. Those places may not carry rich formatting. Unicode characters can travel with the text.
This site turns common numbers, letters, and symbols into their real Unicode superscript or subscript equivalents. Conversion happens in the browser, so there is no account to create and no document to upload.
Why formulas and tiny text are separate
A formula such as 6.02e23 should become 6.02e²³. Raising the whole number would make it harder to read and would change the usual scientific notation. Tiny text has a different goal. Someone making a compact profile name may want every available character shifted.
The two modes keep that choice visible. Formula mode moves the parts that normally belong above or below the baseline. Tiny text converts every character for which Unicode provides a genuine match.
Unsupported letters stay unchanged
Unicode does not contain a complete superscript or subscript Latin alphabet. In particular, there are no true Latin lowercase subscript forms for several familiar letters, including b and c. Borrowing a Greek beta or a raised character from another writing system can make the result look plausible while changing what the character actually is.
The converter leaves an unsupported character where it is. That is why subscript tiny text turns abc123 into ₐbc₁₂₃. The unchanged b and c are deliberate.
How changes are checked
The mapping tables are kept in the project code and tested against common numbers, ordinal endings, chemical formulas, explicit x^2 and x_1 notation, and scientific notation. Browser checks cover typing, mode switching, copying, keyboard controls, and mobile layout. We also keep explanatory examples close to the converter so a result can be judged before it is copied.
What the tool cannot promise
The copied characters are real Unicode, but each app chooses its own font. A character may look taller, narrower, or slightly uneven after it is pasted. Some systems may read decorative superscript text one character at a time, which is worth considering for accessibility. For formal equations, typesetting systems such as MathML, LaTeX, or an editor's native formatting may be a better fit.
Corrections are welcome
If an example is misleading or a standard character is missing, use the contact page and include the input, expected output, and app where you pasted it. A small reproducible example is much easier to fix than a screenshot with no source text.
