Free Case Converter
Convert text to UPPERCASE, lowercase, Title Case, camelCase, snake_case, and more, instantly.
How to use this tool
Type or paste your text into the top box, then click any of the case buttons below it. The transformed text appears immediately in the read-only result box underneath, so your original text is always preserved and ready to convert a different way.
Title Case and Sentence case keep your original spacing and punctuation while adjusting capitalization. camelCase, snake_case, and kebab-case treat spaces and punctuation as word breaks and rebuild the text using the naming convention's own separator.
This is handy for formatting headlines, cleaning up text pasted from another source, or converting a phrase into a variable name format used in code, such as camelCase or snake_case.
