Common case-conversion examples
Headings and titles
Use Title Case for headings when your style guide calls for capitalized principal words. Use sentence case when only the first word and sentence starts should be capitalized.
Code and filenames
camelCase, snake_case, and kebab-case are useful for variable names, data fields, URLs, slugs, and filenames. Always review technical identifiers before replacing them in working code.
Frequently asked questions
Does the converter change punctuation?
Most punctuation is preserved. Word-separator modes normalize runs of spaces and punctuation into the chosen separator.
Is Title Case identical to every style guide?
No. Style guides disagree about which short words remain lowercase. This tool uses a practical general-purpose rule and preserves the first and last words as capitalized.
Will camelCase preserve acronyms?
No guarantee. The converter normalizes words before rebuilding the identifier, so review acronyms and product names.
Is my text uploaded?
No upload is performed by this tool. Conversion happens in your browser.
Conversion method
Uppercase and lowercase use the browser’s Unicode-aware case conversion. Sentence case lowercases the text and capitalizes the first letter after the start of the text or sentence-ending punctuation. Title Case capitalizes main words while leaving a small set of common short words lowercase except at the beginning and end.
camelCase, snake_case, and kebab-case first split text into normalized words, then rebuild those words using the selected naming convention.
