Our case converter is the fastest way to transform text between different capitalization styles. Whether you accidentally typed in caps lock, need to format titles properly, or want to fix inconsistent capitalization, this ferramenta gratuita handles it instantaneamente—no account required, no software to install.
The tool supports seven conversion modes: UPPERCASE converts everything to capital letters, perfect for headings, acronyms, and emphasis. lowercase makes everything small, useful for reformatting shouting text or creating a subdued tone. Title Case capitalizes the first letter of each word, following standard title formatting rules. Sentence case capitalizes only the first letter of each sentence, ideal for paragraph text.
For creative purposes, aLtErNaTiNg CaSe creates the popular mocking text style used in memes and redes sociais. Inverse case flips existing capitalization—turning upper to lower and vice versa—useful for fixing caps lock mistakes. Capitalize Words ensures every word starts with a capital, regardless of word length.
Professionals use case conversion constantly: writers fixing manuscript formatting, marketers preparing ad copy, developers standardizing code comments, students formatting citations, and redes sociais managers crafting posts. Our tool processes text instantaneamente no seu navegador—your content never leaves seu dispositivo, ensuring complete privacidade.
Unlike basic find-and-replace, proper case conversion handles edge cases intelligently. Title Case, for example, correctly handles contractions, preserves intentional capitalizations, and follows typographic conventions. Whether you're processing a single headline or an entire document, the conversion maintains your text's integrity while transforming its appearance.

Title Case capitalizes the first letter of major words while keeping minor words (like 'a', 'the', 'and', 'of') lowercase, unless they start the title. Use it for headlines, article titles, book titles, and headings. Example: 'The Art of War' not 'The Art Of War'.
Sentence case capitalizes only the first letter of the first word in each sentence, like normal writing. Title Case capitalizes the first letter of most words. Use Sentence case for body text and paragraphs; use Title Case for headlines and titles.
