Convert text between uppercase, lowercase, title case, camelCase and more.
A case converter is an online text tool that instantly changes the capitalization style of any text. Whether you need UPPERCASE for emphasis, lowercase for casual writing, Title Case for headlines, or Sentence case for proper writing, our free text case converter handles it all with a single click — no typing required.
In everyday writing, use Sentence case for paragraphs and Title Case for headings. In programming, camelCase is standard for JavaScript and Java, while snake_case is preferred in Python. Database column names often use snake_case. URL slugs use kebab-case (like "my-article-title"). CSS class names use kebab-case while JavaScript objects use camelCase.
Proper capitalization matters for SEO. Title tags and meta descriptions should use Title Case for better click-through rates. URL slugs should always be lowercase with hyphens (kebab-case) — this is Google's recommended format. Heading tags (H1, H2, H3) typically use Title Case or Sentence case for readability and SEO impact.
