Unicode Superscript & Subscript Converter

Turn supported letters, digits, and operators into copyable Unicode superscript and subscript text.

Superscript

Subscript

Unicode coverage varies

Unicode does not include superscript and subscript versions of every character. Unsupported characters remain unchanged so the result is predictable.

Worked example and guidance

Use Superscript & Subscript Converter with a checkable example

Example input

x2 + H2O

Expected output

x² + H₂O where supported by Unicode

For the example above, the output should be read as the browser-side result for the exact input and options shown. Superscript & Subscript Converter performs the browser-side transformation or calculation, but the mathematical convention, units, domain, and intended publishing format still come from your problem.

How to use it

  1. Enter or paste a small known tool input before using a larger real-world example.
  2. Choose the required options and run Superscript & Subscript Converter; keep the original input available for comparison.
  3. Read the result together with its displayed assumptions and a second representation, then copy or export only after the check passes.

Useful for

  • Creating a small verified example
  • Preparing copy-ready mathematical notation
  • Checking a result before publication

Limits and checks

  • Unsupported syntax must be simplified
  • The result depends on the convention selected
  • Important work should be verified independently

Superscript & Subscript Converter FAQ

Does Superscript & Subscript Converter upload my input?

No. The published tool runs in the browser. Avoid placing confidential material in share URLs or exported files that you later send elsewhere.

How should I verify a Superscript & Subscript Converter result?

Start with the worked example, inspect the displayed assumptions and a second representation, and compare one result with an independent calculation or representation.

What should I do when the input is rejected?

Reduce the input to the smallest failing tool input, check delimiters and supported syntax, then add the remaining structure back one step at a time.
