Technical details

Case conversion looks trivial in English but becomes interesting in Turkish (dotted I), German (sharp s), and any language where uppercase has different cardinality from lowercase. JavaScript `toUpperCase()` and `toLowerCase()` honour the Unicode case-folding rules, which means our converter Just Works for the vast majority of human languages.

Programmatic cases — camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE_CASE — are language-agnostic conventions used in code. The converter first splits the input into words by detecting boundaries (whitespace, case changes, digits adjacent to letters), then rejoins them with the appropriate separator and capitalisation rule.

Title Case follows the AP style by default: capitalise every word longer than three letters, plus the first and last word. Sentence case capitalises only the first letter of each sentence and proper nouns (the latter cannot be detected automatically, so manual review is recommended for high-stakes copy).

For URL slugs, prefer kebab-case: it is human-readable, accepted by every browser, and search engines treat hyphens as word separators (underscores are not).

Frequently asked questions

Does the converter handle non-Latin scripts?
Yes. Case conversion uses Unicode rules, so Cyrillic, Greek and Latin variants all work correctly.
What is the difference between camelCase and PascalCase?
camelCase keeps the first letter lowercase (myVariable), PascalCase capitalises every word (MyClass).
Which case is best for URLs?
kebab-case. Search engines treat hyphens as word boundaries, so the URL stays readable and SEO-friendly.
Can I convert very long texts?
Yes. The conversion is purely client-side and runs in milliseconds even on multi-megabyte input.
Will my text be sent to a server?
No. All conversions happen in your browser.
