About Case Conversion
Text case conversion is a common need when working with content. Whether you accidentally typed with caps lock on, need to format a title properly, or want to standardize text for data processing, our case converter handles it all.
The tool supports multiple case formats. UPPERCASE makes all letters capital, useful for emphasis or headers. lowercase converts everything to small letters, common for data normalization. Title Case Capitalizes The First Letter Of Each Word, perfect for headings and book titles.
Sentence case capitalizes only the first letter of each sentence, maintaining natural readability. For creative effects, alternating case (LiKe ThIs) and inverse case (where lowercase becomes uppercase and vice versa) are available.
All conversions preserve numbers, punctuation, and spacing. The tool works with any language that has case distinctions, including English, French, German, Spanish, and more.
