What Case Converter does
Case conversion changes letter capitalization or turns words into common identifier styles. Writing modes retain punctuation and spacing, while camel, snake, and kebab modes extract words and join them with predictable separators.
Examples
- Turn a heading into sentence case.
- Create `camelCase` for a JavaScript variable.
- Convert a phrase to `snake_case` or `kebab-case`.
Frequently asked questions
Is my input uploaded?
No. This tool processes its input locally in your browser. Normal page requests do not include the contents you enter or select.
Does title case follow every editorial style?
No. It capitalizes each word and does not apply publication-specific rules for articles, conjunctions, or prepositions.
Will it work in every browser?
The tool uses modern browser APIs. Current Chromium, Firefox, and Safari releases provide the best support; the page displays a clear error when a required capability is unavailable.
