This tool converts any text between different letter cases. It handles everyday tasks like fixing accidentally capitalized text, formatting headlines for your blog, or normalizing data that came from different sources.
UPPER CASE converts everything to capital letters. Good for headings, acronyms, or emphasizing a word in a sentence. The entire text gets transformed with no exceptions.
lower case converts everything to small letters. Use this to fix text that was typed with Caps Lock on, or to normalize names and email addresses before storing them.
Sentence case capitalizes the first letter of each sentence while leaving the rest in lowercase. This is the most common format for paragraphs and articles. If you have a block of all-caps text, Sentence case restores it to normal readability.
Title Case capitalizes the first letter of each word. Commonly used for headlines, article titles, book names, and section headings. Most style guides recommend Title Case for blog post titles.
iNVERSE cASE flips the case of every letter. Upper becomes lower and vice versa. This is mostly for fun creative effects or when text comes in with reversed case formatting.
Just paste your text in the box above, click the case you want, and the result appears instantly. Line breaks, spaces, and punctuation are preserved. Only the letters change.
