Transforms
All processing stays in your browser. Counts use Unicode code points for characters; words are letter/number sequences. Title and sentence case are heuristics, not full linguistic rules.
Transforms run in your browser. Nothing is uploaded.

How the case converter works

Review: Check output.
Copy: Use elsewhere.
Stuck with ALL CAPS paste?
PDFs, emails and code renames need one-click case changes.
Paste, click a transform, copy.

- slugify strips accents approximately.
- camelCase splits on spaces and hyphens.
- Copy before navigating away.
Transforms
Locale-aware upper/lower; structural cases for code.
Privacy
No server round-trip for transforms.
