Case Converter

Convert text between uppercase, lowercase, title case, and more.

About this Case Converter

Case Converter transforms text between uppercase, lowercase, title case, sentence case, alternating case, camelCase, PascalCase, snake_case, and kebab-case without retyping. Designers rename layers and components; developers normalize identifiers and API fields; writers fix ALL-CAPS pastes from PDFs and email. Pick the output style that matches your style guide or coding convention, preview the result, then copy into your editor or CMS. Identifier modes collapse spaces into separators so headlines become route-safe tokens. Conversion stays on your device for quick, private edits of brand decks and unpublished copy. Prefer title case for marketing headlines, sentence case for product UI strings, and kebab or snake case for URLs and CSS class names depending on your codebase conventions. Batch-convert navigation labels before a design-system rename lands in production CSS.

Frequently asked questions

What is title case versus sentence case?
Title case capitalizes major heading words. Sentence case capitalizes the first letter of the sentence; proper nouns still need your judgment.
Do camelCase and snake_case remove spaces?
Yes. Those modes collapse whitespace into identifier-friendly separators used in code and paths.
Will punctuation be preserved?
Prose modes mostly keep punctuation. Identifier styles strip or replace characters illegal in code names.
Should I title-case an entire article?
Usually no—apply title case to headings and labels, not long paragraphs.
Is Unicode supported?
Modern browsers handle many Unicode letters. Review uncommon scripts after conversion.
