What is the difference between Title Case, Sentence case and Capitalized Case?
Sentence case capitalizes only the first letter of each sentence. Title Case capitalizes the main words of a title and keeps short words such as "of" and "the" lowercase. Capitalized Case capitalizes the first letter of every word. For example: The art of war (sentence), The Art of War (title), The Art Of War (capitalized).
Which case style should I use for headings and titles?
Use Title Case for article titles and headings, or Sentence case if your style guide prefers a lighter look. Use Capitalized Case for names and labels where every word starts with a capital.
What are fancy text styles like bold, bubble and strikethrough?
Fancy text styles turn normal letters into Unicode characters such as bold letters, circled letters or crossed-out letters. You can copy and paste them into bios, posts and messages. Support can vary between apps, fonts and devices.
What are developer case styles such as camelCase and snake_case?
Developer case styles join multiple words into one name without spaces. camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case are used for variables, class names, filenames, URLs and configuration keys.
About Convert Case Tool
The Convert Case tool helps you quickly change text between different letter cases such as lowercase, UPPERCASE, Capitalized Case, Title Case, and more. It makes text formatting simple and saves you from manually changing letters one by one.
It is useful for students, developers, writers, designers, content creators, and anyone who works with text regularly. Whether you are formatting a heading, preparing content, working with code, or simply changing the style of your text, you can choose the case you need in just one click.
The tool groups its styles into three sets. Text case styles (sentence, lower, upper, capitalized, title, alternating and inverse) change how letters are capitalized. Fancy text styles (wide, strikethrough, bold and bubble) turn plain text into Unicode characters you can paste into bios and posts. Developer case styles (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case) join words into names for code, files and URLs.
This tool runs completely in your browser, so your text remains private and secure. Your text does not need to be uploaded to a server for conversion, and you can easily copy or download the converted text for later use.
