Frequently asked questions
What is Title Case versus Sentence case?+
Title Case capitalises each major word (skipping words like “a”, “and”, “of”); Sentence case only capitalises the first word of each sentence.
Can it convert a heading to a URL slug?+
Yes. Use kebab-case to get a lowercase, hyphen-separated slug suitable for URLs.
Does it handle accented letters?+
Yes. Unicode letters are supported for all case transformations.
Is my text sent anywhere?+
No. All conversion runs locally in the browser.
