About Case Converter
Case conversion is one of those tasks that sounds trivial but wastes hours when you're manually editing dozens of lines. Our free online Case Converter transforms text into any case format in a single click — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and more. Paste your text, pick a format, copy the result — done.
Developers use case converters constantly: converting database column names to camelCase for JavaScript variables, converting API keys to SCREAMING_SNAKE_CASE, transforming class names to PascalCase, or turning kebab-case CSS properties into readable human text. Our tool handles all standard programming case formats with one click.
Writers and editors use case converters for quickly fixing ALL-CAPS titles to Title Case, correcting accidentally capitalized text, or formatting chapter headings consistently. Marketers use it for brand naming, slogan formatting, and hashtag generation (converting "my brand name" to "#MyBrandName").
The tool handles Unicode correctly — accented characters (é, ü, ñ), Cyrillic, and other non-ASCII letters are preserved and case-converted where applicable. This makes it suitable for multilingual content.

Frequently Asked Questions
camelCase starts with a lowercase letter (e.g., 'myVariableName'). PascalCase starts with an uppercase letter (e.g., 'MyVariableName'). PascalCase is used for class names; camelCase is used for variable and function names in most languages.
Title Case capitalizes the first letter of each major word. Most style guides (APA, MLA, Chicago) exclude articles (a, an, the), prepositions, and short conjunctions from capitalization unless they start the title.
