Case Converter
Convert text to uppercase, lowercase, Title Case, Sentence case or alternating case directly in your browser.
What is a case converter?
A case converter changes the capitalization of existing text without changing its words. It is useful for headings, names, drafts, product text, filenames and other content that needs consistent capitalization.
Title case vs. sentence case
Title Case capitalizes the main words in a heading, while sentence case capitalizes the first word and keeps the rest mostly lowercase. Neither should be confused with ALL CAPS, which is better suited to short labels than long paragraphs.
