Frequently Asked Questions
What is title case?
Title case capitalizes the first letter of each major word in a text. It's commonly used for headlines, book titles, and article headings. Minor words like 'a', 'an', 'the', 'in', 'on' are typically left lowercase.
What is sentence case?
Sentence case capitalizes only the first letter of each sentence, leaving the rest lowercase. This is the standard format for body text, paragraphs, and most writing.
Does this tool work with multiple paragraphs?
Yes. You can paste text with multiple paragraphs, and each case conversion mode will properly handle all paragraphs in your text.
Is my text sent to any server?
No. All text conversion happens locally in your browser. Your text never leaves your device.
What is the difference between title case and sentence case?
Title case capitalizes the first letter of each major word (e.g., 'The Quick Brown Fox'), while sentence case only capitalizes the first letter of the sentence and proper nouns (e.g., 'The quick brown fox').
