Frequently asked questions
Should I review automatically generated title case?
Yes. Editorial styles differ, and automatic rules do not always identify proper names or acronyms correctly.
Is Case Converter free?
Yes. This public tool does not require an account, payment or subscription.
Where is my input processed?
The tool-specific processing runs in your browser. Website delivery still involves hosting requests; see the privacy policy for details. Read the privacy policy.
What is the difference between title case and sentence case?
Title case capitalises the first letter of every word (“How To Merge PDF Files”). Sentence case capitalises only the first word of each sentence (“How to merge PDF files”). Sentence case is easier to read for most headings and buttons.
How do I fix text typed with Caps Lock on?
Paste it here and copy the lowercase or sentence case version from the results. All four versions are shown at once.
