The Fast Way to Fix Text Capitalization

Manually re-typing a sentence just to fix its capitalization is tedious and error-prone. The Text Case Converter lets you paste any block of text and reshape its letter case in a single click. Whether you accidentally left Caps Lock on, need a clean headline for an article, or want a tidy title for a spreadsheet column, this tool handles it instantly — right inside your browser, with nothing uploaded anywhere.

Every Case Style Explained

UPPERCASE converts every letter to a capital, ideal for emphasis, acronyms or banner text. lowercase does the opposite, useful for normalizing messy input, email addresses or hashtags. Sentence case capitalizes only the first letter of each sentence — the natural style for paragraphs and body copy. Title Case capitalizes the important words while leaving small connecting words lowercase, which is the format most style guides recommend for headlines and titles.

Capitalize Each Word puts a capital at the start of every word, perfect for names, labels and menu items. tOGGLE cASE flips the case of each character, a quick way to correct text typed with Caps Lock stuck on. The two cleanup actions — Remove Extra Spaces and Remove Line Breaks — collapse double spaces and stray blank lines into clean, single-spaced text.
