Instantly switch any text between UPPERCASE, lowercase, Title Case, Sentence case, and aLtErNaTiNg case. Our free case converter is a lifesaver when you have typed a whole heading with Caps Lock on, or need to normalize messy spreadsheet data. One click reformats everything — no retyping required.
The case converter is handy for fixing headings, normalizing data, and formatting titles. Title case follows common headline rules and sentence case capitalizes the first letter after each period.
Manually fixing capitalization wastes time and introduces new typos. Bloggers use Title Case for headlines, developers normalize database entries to lowercase, and students rescue accidental ALL-CAPS essays in seconds. Because the conversion runs locally in your browser, even sensitive documents never leave your device, and there is no practical length limit.
Title Case capitalizes the first letter of each major word — the style used for book titles and headlines, like 'The Quick Brown Fox Jumps'.
It lowercases everything first, then capitalizes the first letter of each sentence — the style of normal prose and paragraphs.
No practical limit. Since everything runs in your browser with plain JavaScript, even very long documents convert instantly.
UPPERCASE and lowercase modes convert every letter, so acronyms change too. If your text contains acronyms you want to preserve, convert first and then fix those few words manually.
