Frequently Asked Questions
- What is a case changer?
- A case changer is a tool that converts text between different letter cases — UPPERCASE, lowercase, Title Case, Sentence case, and stylized variants. It is the same thing as a case converter or text case changer.
- How do I change text from UPPERCASE to lowercase?
- Paste your text into the editor above, then click the lowercase button. The entire content is converted in place. Use the Copy button to copy the result.
- Can I decapitalize text online?
- Yes — paste the text and click lowercase to decapitalize (decaps) every letter at once. For only-first-letter-of-sentence behaviour, use Sentence case.
- How do I fix a CAPS LOCK mistake?
- Paste the all-caps text, then click Sentence case for normal prose or Title Case for headings and titles. The case is rewritten in one step.
- What does iNVERSE cASE do?
- iNVERSE cASE flips every uppercase letter to lowercase and every lowercase letter to uppercase — handy for stylized social posts or quickly inverting text typed with the wrong case key.
