Case Converter
Convert text between different cases - upper, lower, title, sentence, camel, and snake case
About this Tool
The Case Converter is a powerful text formatting tool that instantly transforms text between different letter case styles. It supports six common case formats: UPPERCASE (all capitals), lowercase (all small letters), Title Case (first letter of each word capitalized), Sentence case (first letter of each sentence capitalized), camelCase (used in programming), and snake_case (words separated by underscores). This tool is essential for writers, developers, content creators, and anyone who needs to quickly reformat text for different purposes without manual editing. Simply paste your text and click the desired format for instant conversion.

Pro Tips
- !
Title Case Nuances
Proper title case capitalizes major words but not articles (a, an, the), short prepositions (in, on, at), or coordinating conjunctions (and, but, or) unless they're the first word. This tool follows standard title case rules automatically.
- !
Sentence Case vs Title Case
Use sentence case for body text and most casual content. Use title case for headlines, book titles, and formal headers. Understanding which to use improves readability and professionalism.
- !
Programming Case Conventions
camelCase is standard in JavaScript and Java. snake_case is common in Python and Ruby. PascalCase (like title case but no spaces) is used for class names. Choose the right convention for your language.

Preserve Special Characters
The converter maintains numbers, punctuation, and special characters while changing letter cases. This ensures your text structure remains intact during conversion.
