❓ Frequently Asked Questions
Which words are not capitalized in a title?+
In title case, short words stay lowercase: articles (a, an, the), coordinating conjunctions (and, but, or, nor) and short prepositions (at, by, in, of, on, to, up) — unless they are the first or last word, which are always capitalized. The Title Case mode applies these rules for you automatically.
How do I change ALL CAPS to lowercase?+
Paste the text and click lower case to convert every letter, or Sentence case to keep the first letter of each sentence capitalized — the instant fix for accidental caps-lock typing.
What is Title Case?+
Title Case capitalises the first letter of every major word. It's used for headings, titles and proper nouns — for example: 'The Quick Brown Fox'.
What is Sentence case?+
Sentence case capitalises only the first letter of the first word in a sentence, just like normal writing. Example: 'The quick brown fox jumps.'
What is camelCase?+
camelCase starts with a lowercase letter and capitalises the first letter of each subsequent word with no spaces. Used widely in programming: 'myVariableName'.
What is snake_case?+
snake_case replaces spaces with underscores and uses all lowercase letters. Common in Python and database column names: 'my_variable_name'.
What is kebab-case?+
kebab-case replaces spaces with hyphens and uses all lowercase. Used in URLs and CSS class names: 'my-variable-name'.
