Every case route uses the same Unicode-aware transformations. Casing changes only text with uppercase or lowercase forms; whitespace, punctuation, numbers, emoji, and uncased scripts are preserved.
The general converter keeps the common transformations together while focused routes provide a direct workflow. Processing remains browser-local.
Using this tool
Convert the current text to uppercase, lowercase, simple title case, sentence case, or alternating case.
Example: `hello WORLD` can become `Hello World` in simple title case.
Whitespace, punctuation, numbers, and emoji stay in place; only cased letters are transformed.
Simple title and sentence modes are deterministic helpers, not editorial style guides.
Conversion is performed in the browser. Copying or downloading happens only when you choose those actions.
