Use cases

Turn names, labels, headings, constants, and short messages into all-caps text without changing the words themselves.

Normalize pasted text into lowercase for tags, slugs, search cleanup, or quick formatting before another workflow.

Use title case for headings and sentence case for cleaner paragraphs, support copy, or notes that should read naturally.

Is my text uploaded?+

No. The conversion happens locally in your browser.

Can I convert long text?+
