Everything happens in your browser

The file and text never leave your device.

Five casing styles

Convert text to UPPERCASE, lowercase, Title Case, sentence case, or inverted case while reviewing a block quickly.

Normalize labels, headings, variable names, and editorial copy without installing software or creating an account.

Privacy for pasted text

Your browser processes the content locally. Still use test or anonymized data when text may contain sensitive information.

FREQUENTLY ASKED QUESTIONS

Is my text uploaded?

No. Conversion runs in your browser and the content is not transmitted.

Can I convert long text?

Yes, although the practical limit depends on the memory available in your browser.

Are line breaks preserved?

Yes. The tool changes letter casing without removing the text structure.

Can I use it for code?

Yes, but review identifiers and strings because changing case can change their meaning.
