Change casing in one step
Paste text and choose a case style. The converted result replaces the text in the editor, ready to copy. Word and character counts update immediately after each change.
Review proper names
Automated case changes cannot know brand spelling, acronyms or proper nouns. Check those details after conversion, especially in headings and published copy.
Frequently asked questions
Can I undo a conversion?
Use Undo conversion to restore the text from before the most recent case change. Editing or clearing the text starts a new history.
