Questions about Case Converter
Does Title Case capitalise small words?
It follows the common convention: articles and short prepositions stay lowercase unless they start the title.
How does camelCase split words?
On spaces, hyphens and underscores; existing capital letters are treated as word breaks.
Are acronyms preserved?
Not automatically. Convert to UPPER first if an acronym must stay intact.
Is my text uploaded?
No, conversion is local to the browser.
