Case Converter

New

Convert text to UPPER, lower, Title, camelCase & more.

A case converter transforms text between writing and coding formats without manual editing. It is useful for content cleanup, headline formatting, variable naming, and preparing text for different publishing contexts.

This tool supports uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE. You can switch formats instantly and copy the converted output in one click.

All conversions are deterministic and run locally in your browser, keeping your text private.

: Title Case capitalizes each major word, while Sentence case capitalizes only the first word and keeps the rest mostly lowercase.
: Yes. The converter splits mixed-case and delimiter-based text to produce common programming naming styles.
: Numbers are preserved. Some punctuation is treated as separators when building structured cases like snake_case.
