What Each Case Does
- UPPERCASE / lowercase — every letter converted; the classics for headings or normalising shouty text.
- Title Case — Capitalises Every Word; common for headlines and titles.
- Sentence case — capitalises the first letter of each sentence and lowercases the rest.
- camelCase / PascalCase — words joined without spaces, used for variable and class names in code.
- snake_case / kebab-case — words joined with underscores or hyphens, used in filenames, URLs and code.
- aLtErNaTiNg — alternates letter case, mostly for memes.

Frequently Asked Questions
Is my text uploaded anywhere?
No. Every conversion runs in JavaScript in your browser. The text never leaves your device, nothing is logged, and it disappears when you close the page.
What is the difference between camelCase, PascalCase, snake_case and kebab-case?
They are the four common identifier styles in programming: camelCase starts lowercase with each later word capitalised (JavaScript/Java variables), PascalCase capitalises every word (class names), snake_case joins lowercase words with underscores (Python), and kebab-case joins them with hyphens (URLs, CSS classes, filenames).
How is Sentence case different from Title Case?
Sentence case capitalises only the first letter of each sentence. Title Case capitalises every word. Use sentence case for body text and title case for headings.
What happens to punctuation in the code cases?
For camelCase, PascalCase, snake_case and kebab-case the text is split on every non-alphanumeric character, so punctuation is removed. The other conversions (UPPERCASE, lowercase, Title, Sentence) keep punctuation untouched.
Can I convert a whole document?
Yes — paste as much text as you like; the live counter shows characters, words and lines. Since everything runs locally, large texts are limited only by your browser's memory.
