What is Text Case Converter?

The Text Case Converter transforms text between capitalization formats. Supported modes include uppercase, lowercase, title case, sentence case, camelCase, PascalCase, and snake_case. You paste or type text, select a format, and the tool converts it instantly. It handles international characters and accented letters. All processing happens in the browser.

This tool applies string transformation rules to convert text between cases. Uppercase converts all letters to capitals. Lowercase converts all letters to small. Title case capitalizes the first letter of each word. Sentence case capitalizes the first letter of each sentence. camelCase and PascalCase are programming conventions, and snake_case uses underscores between words.
