Case Converter — Transform Text Case in One Click

This free case converter turns any text into UPPERCASE, lowercase, Title Case, Sentence case, alternating case, or inverted case instantly. It works 100% in your browser, so your text is never sent to a server and your clipboard content stays private.

Available Text Cases

UPPERCASE — all letters capital, ideal for headings and acronyms. lowercase — all letters small, for slugs and clean URLs. Title Case — every word capitalized with a smart list of small words (a, an, the, and, of…) left lowercase. Sentence case — only the first word and proper nouns capitalized, the natural style for articles. aLtErNaTiNg — alternating upper and lower, popular for social media emphasis. InVeRsE — flips the case of every letter in your text.

Why Use a Case Converter

Consistent casing improves readability, keeps brand and UI copy uniform, and simplifies everyday tasks: converting an ALL-CAPS email to a polite sentence case, fixing title case for headlines and blog post titles, or generating lowercase slugs from mixed text. Because the tool runs locally, it handles long documents instantly without any delay.
