Frequently Asked Questions
What is a text case converter?
A text case converter instantly transforms your text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case and kebab-case — saving you from manually retyping or reformatting text.
What is Title Case and when should I use it?
Title Case capitalises the first letter of each major word. Use it for blog post titles, page headings, product names and meta titles in SEO. Example: "How To Improve Your Search Rankings".
What is camelCase used for?
camelCase is the standard naming convention in JavaScript, Java and many other languages for variables and functions. The first word is lowercase; each subsequent word starts with a capital. Example: myVariableName.
What is kebab-case best used for?
kebab-case is the standard format for SEO-friendly URL slugs and CSS class names. Google recommends using hyphens (not underscores) to separate words in URLs. Example: how-to-check-keyword-density.
Text Case Guide: When to Use Each Format
Title Case: For Headings and Titles
Title Case capitalises the first letter of every major word. Use it for blog post titles, page headings, product names, and meta title tags. Most style guides (AP, Chicago, APA) follow slightly different rules about which words to capitalise — our converter uses the most widely accepted web standard: capitalise all words except short prepositions (in, of, at), articles (a, an, the), and conjunctions (and, but, or).

Sentence Case: For Body Text and Descriptions
Sentence case capitalises only the first word of the sentence and proper nouns. It is the standard format for body copy, meta descriptions, social media posts, and email subject lines. Many brands also prefer Sentence case for headings on their website as it feels more conversational and readable.

kebab-case: For SEO-Friendly URLs
kebab-case uses all lowercase letters with hyphens between words. Google officially recommends hyphens (not underscores) to separate words in URLs. This means "how-to-check-keyword-density" is better for SEO than "how_to_check_keyword_density" or "howtocheckkeyworddensity". Use the URL slug generator to automatically convert any title to a clean kebab-case slug.
camelCase and snake_case: For Developers
camelCase (myVariableName) is the standard for JavaScript variables and functions. PascalCase (MyClassName) is used for class names in most object-oriented languages. snake_case (my_variable_name) is the convention in Python and database column names. Use the converter to instantly switch between formats when copying code or variable names between different codebases.
UPPERCASE and lowercase: Specific Use Cases
ALL CAPS is used for acronyms, legal disclaimers, and emphasis — but avoid it in body text as it is harder to read and comes across as shouting. All lowercase has become a trend in brand names (typeface, notion, figma) and casual social media writing. For most SEO content, Sentence case or Title Case is the right choice.
