Title Case follows standard title capitalization rules — small linking words like "a", "the", "of" and "and" stay lowercase unless they start the sentence, matching how headlines and book titles are usually styled. Capitalize Each Word simply capitalizes the first letter of every word, no exceptions — useful for names or list items rather than proper titles.
These are programming naming conventions. camelCase (firstWordLower) and PascalCase (FirstWordUpper) are common for variables, functions and class names in languages like JavaScript and Java. snake_case (words_with_underscores) is common in Python and databases, while kebab-case (words-with-hyphens) is common in URLs and CSS class names.
Yes — Sentence case detects sentence boundaries (periods, question marks, exclamation marks) and capitalizes the first letter after each one, rather than just capitalizing the very first letter of the whole text.
Yes — there's no length limit. Paste an entire paragraph, article, or list and the conversion applies instantly to the whole thing.
