What is Title Case Converter?
The Title Case Converter is a free, browser-based tool that capitalizes the major words in your titles and headings while leaving articles, short prepositions, and coordinating conjunctions in lowercase. Choose between AP Style, the Chicago Manual of Style, or a simple all-words rule to match your publication standard. The converter always capitalizes the first word, optionally capitalizes the last word, preserves all-caps acronyms like NASA and HTML, and intelligently handles hyphenated compounds such as Co-Op and Self-Aware.
