What each option does

UPPERCASE and lowercase change every letter. Title Case capitalises the first letter of every word and lowercases the rest. Sentence case lowercases everything, then capitalises the first letter of each sentence. camelCase and PascalCase join words together with capitals (myFileName, MyFileName); snake_case joins them with underscores and kebab-case with hyphens (my_file_name, my-file-name). tOgGlE cAsE alternates small and capital letters.

Title Case here capitalises every word, including short ones like 'and' and 'of', which some style guides keep lowercase. Adjust those by hand if your publication follows AP or Chicago style.

Watch out for names and acronyms

Title Case and Sentence case lowercase the rest of each word, so NASA becomes Nasa and iPhone becomes Iphone. Check names after converting. The code-style options (camelCase, snake_case, kebab-case) keep only plain letters a to z and numbers, so accented letters such as é are removed; they're meant for identifiers, not prose.

Key Features & Practical Use Cases

  • Turning a heading into Title Case for a blog post or document.
  • Making variable, file or URL names in camelCase, snake_case or kebab-case.

Frequently Asked Questions

How do I fix text typed in all caps?

Click Sentence Case. Then fix any names or acronyms that should keep their capitals.

What's the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter (userName); PascalCase starts with a capital (UserName).

Can I undo a conversion?

There's no undo button. Lowercase or uppercase can't restore the original mix of capitals, so keep a copy of your text first.

Is my text uploaded?
